O objetivo deste trabalho foi avaliar os efeitos da estimulação elétrica com corrente de alta voltagem na cicatrização da úlcera de hipertensão venosa crônica, bem como na dor referida, em 13 pacientes portadores de 20 úlceras. Os pacientes diferiram quanto à variação da área da ferida ao longo do tratamento. As curvas individuais indicaram a eficácia do estudo. Dos 13 pacientes que participaram do estudo, observamos que em quatro as feridas cicatrizaram totalmente, enquanto em seis elas reduziram o seu tamanho e em três, aumentaram. Não foram observados efeitos adversos causados pela eletroestimulação. A dor apresentou melhora significativa ou cessação em todos os pacientes / The objectives of this study was to evaluate high voltage electric stimulation effects over chronic venous hypertension ulcer, as well over the referred pain, in 13 patients bearing 20 ulcers. The patients have differed among themselves in relation to the ulcer area throughout the study. The individuals curves indicated the treatment efficacy. It was observed that the ulcer area have been healed in four patients, reduced in six and increased in three of the thirteen patients who has participated in this study. It was not observed adverse effects due to electrical stimulation. The pain has showed meaningful advance or ceasing in all patients

Introdução: A Insuficiência Venosa Crônica (IVC) é responsável pela grande maioria dos sintomas vasculares que acometem os membros inferiores, podendo levar a graves sintomas. A Síndrome de compressão Venosa Cavo-ilíaca (SCVCI) é cada vez mais reconhecida como importante causa da IVC e os métodos de imagem utilizados para o seu diagnóstico fornecem informações anatômicas, mas não trazem informações fisiológicas claras. A importância diagnóstica dos Gradientes pressóricos venosos Cavo-ilíacos precisa ser mais bem estudada e esses ainda não foram comparados ao método padrão-ouro atualmente disponível, o Ultrassom Intravascular (UI). Esse estudo tem como objetivo avaliar a correlação entre as medidas de Pressão intravenosa (PI) e Gradientes pressóricos (GP) e a presença de obstrução venosa significativa no Sistema Cavo-Ilíaco (SCI) estabelecida pelo UI, para o diagnóstico da SCVCI em pacientes portadores de IVC avançada dos membros inferiores. Método: Foram incluídos 50 pacientes com IVC avançada (Classificação CEAP 3 ou superior) de, ao menos, um dos membros inferiores, sem melhora após um ano de tratamento clínico, totalizando 100 membros inferiores. Todos os pacientes foram submetidos, prospectivamente, aos exames de Ultrassom Vascular com Doppler Colorido (UVDC), Angiotomografia Computadorizada Helicoidal (ACTH), Flebografia Multiplanar Ascendente (FMA), Medidas de pressão intravenosa e Ultrassom Intravascular (UI). Os membros inferiores estudados foram divididos em dois grupos: Grupo 1 com obstrução <50% ao UI e Grupo 2 com obstrução >= 50% ao UI. A correlação entre os gradientes e demais variáveis quantitativas foi realizada utilizando o Coeficiente de Spearman. As Curvas ROC foram utilizadas para avaliar qual o melhor desempenho entre os gradientes, na discriminação do grau de obstrução. O desempenho diagnóstico isolado dos GP em comparação com o UI foi avaliado por meio das medidas de Sensibilidade, Especificidade, Valor Preditivo Positivo, Valor Preditivo Negativo e Acurácia. A concordância dos exames com o UI foi realizada por meio do Kappa e do teste de McNemar. A Análise de Regressão Logística foi utilizada para avaliar a contribuição dos GP com a Flebografia, na identificação de pacientes com obstrução significativa. Foram utilizados os programas R (Versão 3.1.0) e SPSS (Versão 2.0). Valores de p<0,05 foram considerados significativos. Resultados: O Grupo 2 apresentou maior predomínio de acometimento do membro inferior esquerdo e maior pontuação nas escalas Visual Analógica para Dor (EVAD), no Escore de Severidade Clínica Venosa (ESCV) e no Questionário de Qualidade de Vida SF-36 (QQV SF-36). As pressões Femorais em repouso (PVF-r) e após hiperemia (PVF-h), bem como os Gradientes Fêmoro-Cava após hiperemia (GFC-h) e o Gradiente Femoral hiperemia-repouso (GFh-r) mostraram-se significativamente mais elevados no Grupo 2 (p=0,001; <0,001; 0,002 e 0,006, respectivamente). As mesmas pressões e gradientes apresentaram correlação significativa com o grau de estenose ao UI, pela análise do Coeficiente de Sperman (PVF-r 0,350, p<0,001; PVF-h 0,379, p<0,001; GFC-h 0,302, p=0,002; GFh-r 0,218, p=0,029), sendo que o melhor desempenho para diagnóstico entre esses parâmetros, pela análise de Curva ROC, foi alcançado pelos gradientes GFC-h e GFh-r. Entretanto, o desempenho diagnóstico isolado dos GP, quando comparados ao UI, apresenta baixos valores de Sensibilidade (<40%), Valor preditivo Negativo (<60%) e Acurácia (<30%), bem como, valores de concordância baixos ao Kappa (<0,3) e discordância desproporcional com o UI pelo teste de McNemar (p<0,05). Os melhores resultados foram encontrados com o UVDC, com ACTH e com a FMA. Ao combinar os resultados da FMA com os GP, ocorre melhora significativa no desempenho diagnóstico, especialmente com a associação da FMA com o GFC-h. Conclusão: Existe correlação significativa entre as Pressões e GP venosos e o grau de estenose aferido ao UI. Entretanto, essa correlação não se traduz em bom desempenho diagnóstico dos GP. O GFC-h acrescenta informação significativa à Flebografia, na identificação dos casos com obstrução >-50% ao UI. / Introduction: Chronic venous insufficiency (CVI) is responsible for most of the vascular symptoms affecting the lower limbs, and can lead to severe complications. Iliac vein compression syndrome (IVCS) is increasingly recognized as an important cause of CVI. The imaging methods used for its diagnosis provide anatomical information but not clear physiological information. The diagnostic importance of the cavo-iliac vein pressure gradients (VPG) requires further study, and they have not yet been compared with the currently available gold standard, the Intravascular ultrasound (IVUS). The aim of this study was to evaluate the correlations between intravenous pressure (IP) and VPG, and the presence of significant IVUS-diagnosed venous obstruction in the cavo-iliac system, for assessment of IVCS in patients with advanced CVI of the lower limbs. Method: The study included 100 lower limbs of 50 patients with advanced CVI (Clinical-Etiology-Anatomy-Pathophysiology - CEAP classification 3 or higher), without symptoms improvement after one year of clinical treatment. All patients prospectively underwent Color Doppler vascular Ultrasound (CDVU), Helical Computed Tomography Angiography (HCTA), Multiplane Ascending Phlebography (MAP), IP measurements, and IVUS. The studied limbs were divided into Group 1 with obstruction <50% by IVUS and Group 2 with obstruction >=50% by IVUS. Spearman\'s correlation coefficient was used to compare gradients and other quantitative variables. Receiver operating characteristic (ROC) curves were used to evaluate the best performance among the gradients for determination of the degree of obstruction. Isolated diagnostic performance of PGs was compared with the IVUS for Sensitivity, Specificity, Positive predictive value, Negative predictive value, and Accuracy. The agreement between the evaluation methods and IVUS was determined using the Kappa statistic and McNemar\'s test. Logistic regression analysis was used to evaluate the contribution of PG to the MAP in identifying patients with significant obstruction. R (Version 3.1.0) and SPSS (Version 2.0) were used for statistical analysis. Values of p<0.05 were considered significant. Results: Group 2 showed a higher prevalence of left lower limb impairment and higher scores on the Visual Analogue Pain Scale (VAPS), the Venous Clinical Severity Score (VCSS), and the Short Form (SF)-36 Quality of Life questionnaire (QOL SF-36). Femoral pressures at rest (FP-r) and after hyperemia (FP-h), Femorocaval gradient after hyperemia (FCG-h), and Femoral gradient after hyperemia (FG-h) were significantly higher in Group 2 (p=0.001, <0.001, 0.002, and 0.006, respectively). Using Spearman\'s correlation coefficient, the same pressures and gradients showed a significant association with the degree of stenosis by IVUS, (FP-r 0.350, p<0.001; FP-h 0.379, p<0.001; FCG-h 0.302, p = 0.002; FG-h 0.218, p=0.029), and the best diagnostic performance among these parameters, using ROC curve analysis, was obtained with the FCG-h and FG-h gradients. However, the isolated diagnostic performance of the PG, when compared with the IVUS, showed low values for sensitivity (<40%), negative predictive value (<60%), and accuracy (<30%), as well as low kappa concordance values (<0.3) and inconsistent disagreement with IVUS, using McNemar\'s test (p <0.05). The best results were found with CDVU, HCTA, and MAP. Combining MAP results with PG led to a significant improvement in diagnostic performance, especially for the association between MAP and FCG-h. Conclusion: There was a significant correlation between VP and PG and the degree of stenosis measured by IVUS. However, this correlation did not result in good diagnostic performance by the PG. The FCG-h adds significant information to MAP in the identification of cases with obstruction >-50% by IVUS.

SAMMANFATTNING    Bakgrund: Venösa bensår är ett globalt vanligt förekommande fenomen, 1–2 % av jordens befolkning anses vara drabbade. Bensår skapar stort lidande för patientens fysiska och psykiska hälsa. Två vanliga förekommande problem är smärta och isolering. Det finns flera metoder för att läka venösa bensår där flerlagers-kompressionslinda anses vara en av det bästa metoderna. Att läka bensår skulle kunna minska patientlidandet.    Syfte: Att sammanställa och jämföra läkningseffekten av två- och fyra-lagerskompressionslindning hos patienter med venösa bensår.   Metod: En deskriptiv design med litteraturöversikt användes som metod där tio vetenskapliga kvantitativa originalartiklar inkluderades. Artikelsökning gjordes i databaserna PubMed och CINAHL.   Resultat: Litteraturöversikten kunde inte påvisa en skillnad mellan 2LB- och 4LB-kompressiongrupperna för förbättrad och fullständig läkningsförmåga. Båda lindorna bekräftades ha en sårläkande effekt. Effekten av kompressionslindorna gav en mer påskyndad sårläkning, än hos patienter utan kompressionsbehandling. Majoriteten av de inkluderade studierna visade på ett liknande resultat i fullständig procentuell läkning mellan två-lagerkompressionslindning (2LB) och fyra-lagerkompressionslindning (4LB).   Slutsats: Litteraturöversikten visar att kompressionsbehandling med 2LB och 4LB har en likvärdig och god sårläkande effekt för patienter. Både 2LB och 4LB är mer gynnsam för sårläkning och välmående än utan kompressionsbehandling för patienter som lever med venösa bensår. / ABSTRACT Background: Venous leg ulcers is a globally common phenomenon, 1-2 % of the world’s population is believed to be affected. Leg ulcers causes great suffering for the patient's physical and mental health. Two common complications are pain and isolation. There are several methods to heal venous leg ulcers, multilayer-compression-therapy is considered one of the best methods. Healing leg ulcers could reduce patient suffering. Purpose: To compile and compare the healing effects of two- and four-layer compression therapy in patients with venous leg ulcers.   Method: A descriptive design with a literature review as method, with ten scientific quantitative original articles were included. Article searches was done in databases PubMed and CINAHL.   Results: The results did not show a difference between the 2LB and 4LB-groups regarding complete and improved healing. However, both methods had a healing effect. The bandages were more effective in accelerating healing in patients, than in patients without compression therapy. Most of the included studies showed a similar result in the percentage of complete healing effect between the two-layer compression therapy (2LB) and four-layer compression therapy (4LB).   Conclusion: This literature review demonstrated that compression therapy with 2LB and 4LB has an equally as well as good healing effect for patients. Both 2LB and 4LB are significantly more beneficial for wound healing and well-being than without compression therapy for patients living with venous leg ulcers.

This critical synopsis of prior work by Clive Beggs is submitted in support of a PhD by published work. The work focuses on venous and cerebrospinal fluid (CSF) anomalies associated with multiple sclerosis (MS) and other neurological diseases. MS is characterized by focal inflammatory lesions, which are often venocentric. Recently a vascular syndrome, chronic cerebrospinal venous insufficiency (CCSVI) has been linked with MS. This syndrome, which is characterized by constricted cerebral venous outflow, has become mired in controversy, with various studies producing conflicting findings, with the result that the science associated with CCSVI has become obscured. Clive Beggs work seeks to bring clarity to the debate surrounding CCSVI by characterizing physiological changes associated with constricted cerebral venous outflow. The work submitted here involves collaborative studies with Robert Zivadinov (University of Buffalo), Paolo Zamboni (University of Ferrara), and Chih- Ping Chung (National Yang Ming University of Medicine). The key findings of these studies are: (i) MS patients, diagnosed with CCSVI, exhibit greatly increased hydraulic resistance of the cerebral venous drainage system; (ii) MS patients experience loss of the small cerebral veins; (iii) MS patients exhibit reduced CSF bulk flow, consistent with mild venous hypertension; (iv) MS patients exhibit increased CSF pulsatility in the Aqueduct of Sylvius, which appears to be linked with mild venous hypertension associated with CCSVI; and (v) jugular venous reflux is associated with white matter and parenchymal volumetric changes in Alzheimer’s patients. Collectively, these findings suggest that extracranial venous anomalies are associated with changes in the intracranial physiology.

The venous leg ulcers most commonly originates from thrombosis, external trauma, physical inactivity or heredity. Comorbidity is common among the patients with venous leg ulcers.  The treatment plan primarily consists of wound dressing and lifelong compression treatment. Aim: The aim of the study was to investigate the patients’ experiences of living with venous leg ulcers. Method: A literature review based on results from 13 empirical studies with qualitative design from Cinahl, PubMed and PsycInfo. The studies have been reviewed by using a review template intended for qualitative studies and the included studies were valued as high and medium high quality. The included studies results were analyzed with the help of an integrated compilation of qualitative research inspired by meta synthesis. Results: Six themes were identified: Self-care had an impact of the well-being, Health care as a part of the daily life, The experience of pain, Perceived self-image and shame and Social and psychological influence. Conclusion: The literature review increased the understanding of what it’s like to live with venous leg ulcers and gave an insight into which knowledge-gaps the health care needs to fill to provide the patients with adequate care.

INTRODUÇÃO: A ecoescleroterapia com espuma (EEE) é um método minimamente invasivo de tratamento das varizes dos membros inferiores. Suas principais vantagens são a indicação para pacientes com alto risco cirúrgico, recuperação precoce pós-intervenção e menor custo inicial em relação aos outros métodos endovenosos. Porém, a taxa de oclusão venosa é variável, especialmente para o eixo venoso troncular com diâmetro maior que 6 mm. OBJETIVO: Comparar duas técnicas de EEE de polidocanol a 3% em veia safena magna (VSM) insuficiente, tendo como desfecho primário a taxa de sucesso completo com uma sessão terapêutica e desfechos secundários a avaliação da qualidade de vida e a taxa de complicações. PACIENTES E MÉTODOS: Seleção de 50 pacientes com varizes primárias superficiais em membro inferior (CEAP - classificação clínica, etiológica, anatômica, patofisiológica - C3) e insuficiência da VSM (6 - 10 mm de diâmetro) medida a 3 cm da junção safenofemoral. Trata-se de um estudo prospectivo, controlado e randomizado realizado no ambulatório do Serviço de Cirurgia Vascular e Endovascular do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Os participantes foram submetidos à EEE preparada pelo método de Tessari. No grupo controle, a injeção foi realizada com uma agulha 18G enquanto que, no grupo alvo, foi utilizado um cateter angiográfico multipurpose 4 Fr., precedendo-se à tumescência salina anestésica no compartimento da VSM, e irrigação contínua do cateter com solução salina antes da injeção da espuma esclerosante. A flebectomia das tributárias varicosas foi realizada em todos os pacientes em nível ambulatorial sob anestesia local tumescente. RESULTADOS: A EEE com cateter angiográfico, precedida de tumescência salina anestésica, com uma única sessão terapêutica, apresentou taxa de sucesso completo superior ao grupo controle (80% versus 36%) com significância estatística (p = 0,012). Houve melhora na qualidade de vida em ambos os grupos. (p < 0,001). Não houve diferença estatística entre os grupos na taxa de complicações (p = 0,584). CONCLUSÕES: A EEE com cateter longo em VSM, precedida de tumescência ecoguiada é um método seguro e eficaz. Apresenta maior taxa de sucesso completo da veia alvo com uma sessão terapêutica em comparação à técnica com cateter curto / INTRODUCTION: Foam echoesclerotherapy is a minimally invasive method to treat varicose veins of the legs. Its main advantages are indication for patients with high surgical risk, early recovery after intervention and lower initial cost in comparison to other endovenous methods. However, the vein occlusion rate is variable, notably for the truncal venous axis with diameter greater than 6 mm. OBJECTIVES: To compare two techniques of echoesclerotherapy with 3% polidocanol foam for the incompetent great saphenous vein (GSV), having as primary outcome the full success rate with one treatment session and secondary outcomes the quality of life and the complication rates. PATIENTS AND METHODS: Selection of 50 patients with primary superficial varicose veins of the leg (clinical, etiologic, anatomic, pathophysiologic - CEAP - classification C3) and GSV incompetence (6-10 mm diameter) measured at 3 cm distal from the saphenofemoral junction. This was a prospective, controlled and randomized trial conducted on the outpatient clinic, Division of Vascular and Endovascular Surgery, University of São Paulo. Patients underwent foam echoesclerotherapy prepared according to the Tessari method. In control group, the injection was performed with an 18G needle whereas in target group, a multipurpose angiographic catheter 4 Fr. was used, preceded by saline anaesthetic tumescence in the GSV compartment, and continuous catheter flush with saline solution before the sclerosing foam delivery. Phlebectomy of the varicose tributaries was performed under local tumescent anaesthesia on outpatient setting. RESULTS: Foam echoesclerotherapy with the angiographic catheter, preceded by saline anaesthetic tumescence yielded complete success rate with a single treatment session higher than the control group (80% versus 36%) with statistical significance (p = 0.012). There was improvement in quality of life in both groups (p < 0.001). There was no statistical difference between the groups in complication rates (p=0.584). CONCLUSIONS: Sclerotherapy with the long catheter, preceded of ultrasound-guided tumescence in the GSV compartment, is a safe and effective method. It yielded higher full success rate of the target vein with a single treatment session in comparison to the short catheter technique

Primary varicose veins are the most frequent cause of CVI. The requirements for each treatment method limits its applicability. Foam sclerotherapy has been shown to be effective, safe and great applicability. OBJECTIVE: Analize patient?s evolution after ultrasound-guided foam sclerotherapy (USGFS). METHOD. Clinical trial without control group. Patients with primary CVI venous ulcer (VU) and great saphenous vein (GSV) reflux were treated with USGFS from June 2015 to June 2016. We evaluate diseases severity, quality of life (QoL), ulcer?s healing and elimination of venous reflux. Patients were followed for 180 days and evaluated by Doppler ultrasound (USD), Aberdeen varicose veins questionnaire (AVVQ) and venous clinical severity score (VCSS). Anatomical and clinical data were collected. AVVQ, VCSS and ulcers diameters were tested by ANOVA method. Patients were grouped according to outcome (VU healing, venous occlusion and reflux elimination) and variables were compared by the Mann-Whitney test or the Fisher exact test. RESULTS: 22 patients were treated (15 men and 7 women) aged 35 to 70 years (56 +/-10.5). There was improvement in quality of life, ulcers diameters antics were reduced (p < 0.001; ANOVA). 77% of VLU were completely healed, 14% remained open with reduced dimensions. Venous reflux was eliminated in 64% of the treated great saphenous vein. Worse QoL patients needed more treatment sessions (? = 0.5449; p = 0.0087; Spearman). Men had better QOL after 180 days and had a higher gain on QOL than women (p = 0.0074). Older patients, patients with larger ulcers, away from work and women had more severe disease (p 0.05 <; ANOVA). No variable related to evolution of clinical severity. Women had more complications (p = 0.017; Fisher) and there was no severe complications. Completely healed VLU and completely occluded GSV were at beginning smaller than not completely healed UV and not completely occluded GSV (p < 0.05; Mann-Whitney). CONCLUSION: The absence of severe adverse effects and improvement of evaluated parameters observed in most patients indicates that USGFS is an applicable alternative to patients with severe CVI. / A insufici?ncia venosa cr?nica (IVC) ? a principal causa de ?lceras nos membros inferiores (UV). Varizes prim?rias s?o a causa mais frequente de IVC. Os diversos tratamentos propostos para varizes com IVC apresentam requisitos que limitam sua aplicabilidade. Escleroterapia com espuma tem se mostrado eficaz segura barata e de grande aplicabilidade. OBJETIVO: Analisar a evolu??o dos portadores de IVC com refluxo da veia safena magna e ?lcera venosa submetidos a escleroterapia ecoguiada com espuma de polidocanol (EEE). M?TODO. Ensaio cl?nico sem grupo controle. Portadores de IVC prim?ria com ?lcera varicosa e refluxo na veia safena magna foram tratados com EEE de forma consecutiva. Os pacientes foram observados por 180 dias entre junho de 2015 e junho de 2016. A evolu??o dos pacientes foi estudada em termos de qualidade de vida (QV) avaliado pelo question?rio Aberdeen para veias varicosas (QA); gravidade da doen?a avaliada por escore de gravidade cl?nica (ECV), elimina??o do refluxo venoso pelo ultrassom Doppler (USD) e cicatriza??o de ?lceras. Foram coletados dados cl?nicos, anat?micos e sociais. QA, ECV, di?metro das ?lceras e a influ?ncia das vari?veis foram comparados pelo m?todo de ANOVA. Os pacientes foram agrupados de segundo desfecho (cicatriza??o de UV, oclus?o e elimina??o do refluxo venoso) e as vari?veis foram comparadas pelo teste de Mann-Whitney ou pelo teste exato de Fisher. RESULTADOS: Foram tratados 22 pacientes (7 homens e 15 mulheres) com idade entre 35 a 70 anos (56 +/- 10,5). Houve melhora na qualidade de vida, redu??o da gravidade da doen?a e redu??o dos di?metros das ?lceras (p<0.001; ANOVA). Houve cicatriza??o completa de 77% das UV, 14% permaneceram abertas com redu??o das dimens?es. Houve elimina??o do refluxo em 64% das VSM tratadas. Pacientes com pior QV necessitaram maior n?mero de sess?es para tratamento da doen?a (?=0.5449; p-valor = 0.0087; Spearman). Homens apresentaram melhor QV ap?s 180 dias e tiveram maior ganho na QV que as mulheres (p = 0.0074; Mann-Whitney). Pacientes mais idosos, portadores de ?lceras maiores, afastados do trabalho e mulheres (p<0,05; ANOVA) apresentaram doen?a mais grave. Nenhuma vari?vel se relacionou a evolu??o da gravidade cl?nica. Mulheres apresentaram mais complica??es (p = 0.017; Fisher) e n?o houve complica??es graves. As UV completamente cicatrizadas e as VSM que apresentaram oclus?o completa apresentavam dimens?es inicialmente menores quando comparadas as UV n?o completamente cicatrizadas e as VSM n?o completamente oclu?das (p<0,05; Mann-Whitney). CONCLUS?O: A aus?ncia de complica??es graves e a melhora observada dos par?metros avaliados na maioria dos pacientes indica que EEE ? alternativa aplic?vel aos portadores de IVC grave.

La prise en charge de l’insuffisance veineuse chronique (IVC) et du lymphœdème repose, traditionnellement, sur des méthodes de compression fondées sur des concepts généralement admis mais insuffisamment éprouvés. Le Projet « Phlébosthène », initié en 2010, comporte le développement et l’application d’outils d’étude biomécanique quantitative de l’œdème et des troubles fonctionnels veineux. Les études n°1 et 2 reposaient sur la volumétrie par mesures étagées de circonférence du membre supérieur chez des patientes présentant un lymphœdème. Elles ont montré la valeur prédictive des variations de volume obtenues par la phase intensive du traitement décongestif quant à l’évolution du lymphœdème à moyen terme et au risque de phénomène de rebond. L’étude n°3 a validé la volumétrie de membre par caméra laser 3D chez des sujets sains et des patients souffrant d’insuffisance veineuse chronique du membre inférieur, en comparaison à la volumétrie par déplacement d’eau, méthode de référence, avec l’avantage majeur de quantifier le volume du pied et de la main. L’étude n°4 comportait, au membre inférieur, la mesure des pressions d’interface, intraveineuse, et intramusculaire sans et avec orthèse de compression dégressive de force 2 et 3, et avec orthèse de compression progressive, au repos, lors d’une manœuvre de flexion-extension du pied en position allongée, et lors d’une manœuvre de haussement sur la pointe des pieds en position debout. L’échographie avec mesure de la force d’appui sur la sonde et analyse automatique d’image calculant l’aire veineuse permettait de déterminer la courbe force / aire d’une veine superficielle et d’une veine profonde du mollet en position allongée et debout. Nous avons inclus 57 patients souffrant d’IVC (21 au stade C1s, 18 au stade C3, et 18 au stade C5 selon la classification CEAP), et 54 sujets sains témoins (18 sédentaires, 18 actifs, 18 sportifs) appariés. Les mesures de pression intraveineuse et intramusculaire ont été réalisées chez un tiers des patients et sujets sains. Le traitement des données échographiques (1776 séquences) étant en cours, nous ne pouvons présenter que des résultats préliminaires et partiels. Les pressions d’interface évoluaient conformément aux attentes, atteignant des valeurs plus élevées sous compression de force 2 que sans compression, sous compression de force 3 que de force 2, et sous compression progressive que sous compression de force 2 ou 3. La compression progressive ne se distinguait nettement des compressions dégressives qu’au niveau du mollet et non de la cheville. Les pressions d’interface étaient généralement plus élevées, sous compression, chez les témoins et les patients au stade C5, et, à un moindre degré, au stade C3, que chez les patients au stade C1s. La pression intraveineuse variait en fonction de la posture et du mouvement et était corrélée à la taille du sujet et sa longueur de jambe en orthostatisme ainsi qu’avec le stade clinique d’IVC. La pression intramusculaire évoluait parallèlement à la compression. Les boucles force / aire veineuse montraient une hystérésis caractéristique, décrivant donc la viscoélasticité des veines examinées. L’analyse complète des résultats permettra de comparer les différentes orthèses de compression et leur effet sur la biomécanique veineuse des sujets sains et pathologiques, avec des données quantitatives sur les caractéristiques viscoélastiques des veines. Nous pourrons évaluer l’effet de l’activité physique en comparant les sujets sédentaires, actifs, et sportifs. L’objectif est, à terme, de produire un modèle mathématique permettant, à partir d’un ensemble limité de données obtenues de façon non-vulnérante, de prédire l’effet des différentes modalités de compression sur la biomécanique veineuse de façon à pouvoir déterminer, grâce à la description géométrique tridimensionnelle du membre, les paramètres individuels optimaux de compression. / The conventional treatment of chronic venous insufficiency (CVI) and lymphedema is based upon mechanical compression, relying on generally admitted but insufficiently proven concepts. The " Phlebosthene " project, initiated in 2010, involves the development and implementation of innovative tools for the quantitative biomechanical evaluation of edema and venous disorders. Studies #1 and #2 were based on the calculation of the upper limb volume by serial circumference measurements in patients with lymphedema. They demonstrated the predictive value of volume variations during the intensive phase of decongestive therapy as for the medium-term outcome and the risk of rebound phenomenon. Study #3 validated segmental limb volumetry by 3D laser scanning in healthy subjects and in patients with lower limb CVI, in comparison with water displacement (reference method), with the major advantage of quantifying the volume of the foot and toes. Study #4 included the measurement, at the lower limb, of interface, intravenous, and intramuscular pressure without and with compression stockings, comparing force 2 and force 3 graduated stockings with so-called progressive compression. Measurements were performed at rest, during flexion-extension movements of the foot while the subject was lying supine, and during a tip-toe test in the standing position. Synchronously recorded B-mode sonography with automatic image analysis allowed calculating the venous area and provided force / area curves of superficial and deep calf veins in the supine and in the standing position. We included 57 patients with CVI (21 at the C1s, 18 at the C3 and 18 at the C5 stage of CVI according to the CEAP classification), and 54 matched healthy controls (18 sedentary, 18 active, 18 sportive). Intravenous and intramuscular pressure measurements were performed in one third of patients. As the processing of the 1776 B-mode sonographic sequences is still underway, we can only offer here partial and preliminary results. Interface pressures evolved as expected, reaching higher values under graduated force 2 compression stockings than without compression, under graduated force 3 than force 2 compression, and under progressive than under graduated compression. Progressive compression clearly distinguished itself from graduated compression only at the calf but not at the ankle level. Interface pressures were generally higher, under compression, in controls and in patients with IVC at the C5 stage, and, to a lesser degree, at the C3 stage, than in patients at the C1s stage. Intravenous pressure varied with posture and movement and correlated with the subject’s size and leg length in orthostatic position, and with the CVI stage. The force / area curves of superficial and deep calf veins exhibited a characteristic hysteresis, yielding viscoelasticity information. When the database will be complete and consolidated, we will be able to compare different compression stockings and their effect on the venous biomechanics of healthy and pathological subjects, providing quantitative data on the viscoelastic characteristics of superficial and deep veins. We will also be able to assess the effect of physical activity on venous biomechanics by comparing sedentary, active, and sportive subjects. The confrontation of interface, intravenous, and intramuscular pressures with these biomechanical data will provide a mathematical model using a limited set of data obtained by simple and non-invasive measurements to predict the effect of compression stockings on the biomechanics of superficial and deep veins, in order to determine, with the help of 3D laser scanning, the optimal individual compression settings.

The venous ulcer is defined as a chronic injury present in the lower third of the legs. It affects the individuals of different age ranges and it is associated to chronic venous insufficiency. It has importance from social and clinic point of view because it compromises their productivity and life quality. So, it becomes a challenge for the health team caring people who have venous ulcer due to its complexity and socio-economical repercussion. Therefore it is essential to create a link with the individual and his/her family promoting the knowledge exchange and approximating the learnings. Thus, through this survey one seeks for contributing with the professionals of health, especially those of Nursing both in the knowledge construction and in the care qualification to the patients with venous ulcers, aiming at the approaching of the professional wisdom to the popular wisdom. The research has as guiding question: What are popular care practices adopted by venous ulcer persons assisted at the angiology outpatient clinic of the Universitary Hospital of Santa Maria, Rio Grande do Sul, Brazil? And as goal: to know the popular care practices adopted by outpatients suffering from venous ulcer attended at the angiology ambulatory of the Universitary Hospital of Santa Maria, RS. This is a field research, which is qualitative, exploratory and descriptive, being developed at the clinic of the referring hospital and at venous ulcer people s household, in the period between December 2012 and March 2013. The research participants are adults and elderly with venous injury. These persons are being accompanied in this ambulatory. The data collection was carried out by a semi-structured interview. Afterwards, the data were transcribed and submitted to the content analysis. Ethical aspects were respected in accordance to the Resolution 196/96 of the National Health Council. The results are presented in an article format: Article 1: People are going to teach me the things and I do them! : popular practices in venous ulcer care; Article 2: Health care in outpatient people with venous ulcer. It can be evidenced that people resort to multiple alternatives in care, seeking for solving their health condition. Among the popular care practices referred by respondents, are: bless, pray, the use of plants and several types of tea, and pluralisms of practices. Besides these, there is the care with the nourishment, with injury and with the rest. Therefore, it is necessary that the health professionals, especially the nurses, know the population socio-cultural reality, which they attend, aiming at a congruent care. / A úlcera venosa é definida como uma lesão crônica presente no terço inferior das pernas. Acomete indivíduos de diferentes faixas etárias e está associada à insuficiência venosa crônica, tendo importância do ponto de vista social e clínico, uma vez que compromete a produtividade e qualidade de vida desses. Assim, torna-se um desafio para a equipe de saúde cuidar das pessoas com úlcera venosa, devido a sua complexidade e repercussão socioeconômica. Considera-se imprescindível a construção de um vínculo com o indivíduo e sua família favorecendo a troca de conhecimentos e aproximando os saberes. Esta investigação, busca contribuir com os profissionais de saúde, especialmente com a enfermagem, tanto na construção do conhecimento como na qualificação do cuidado aos pacientes com úlceras venosas, visando a aproximação do saber profissional ao popular. A pesquisa tem como questão norteadora: Quais as práticas de cuidado popular adotadas pelas pessoas com úlcera venosa atendidas no ambulatório de angiologia do Hospital Universitário de Santa Maria, no Rio Grande do Sul, Brasil? E, como objetivo: conhecer as práticas de cuidado popular adotadas pelas pessoas com úlcera venosa atendidas no ambulatório de angiologia do Hospital Universitário de Santa Maria/RS. Trata-se de uma pesquisa de campo, qualitativa, exploratória e descritiva, desenvolvida no ambulatório do referido hospital e no domicílio das pessoas com úlcera venosa, no período entre dezembro de 2012 e março de 2013. Os participantes da pesquisa são adultos e idosos, com lesão venosa, em acompanhamento neste ambulatório. A coleta de dados foi realizada por meio de entrevista semiestruturada.
