INTRODUCTION: Currently, patients diagnosed with Congenital Heart Disease (CHD) are living longer lifespans, leading to an increased number of these patients presenting for non-cardiac procedures/surgeries. Little research has been recently done analyzing intraoperative complications/risks for CHD patients undergoing non-cardiac surgeries. This study aims to identify common intraoperative events experienced by CHD patients undergoing non-cardiac surgeries using more recent data, while at the same time analyzing to see if there is any difference in frequency of intraoperative events experienced between different types of CHD diagnoses. METHODS: After receiving IRB approval, patients with CHD presenting for non-cardiac procedures/surgeries between the years 2008 and 2012 were pulled from Boston Children’s Hospital’s Electronic Medical records. 1,024 non-cardiac surgical encounters from 362 patients were analyzed to determine average age, average weight, patient gender, average ASA class, frequency of CHD diagnoses, ventricular function, type of non-cardiac procedure, premedication administration, type of induction and type and frequency of intraoperative events experienced. The 1,024 encounters were divided into two groups: those done in patients diagnosed with single ventricle physiology (n=79) and those done in patients diagnosed with non-single ventricle physiology (n=945). Unpaired Mann-Whitney tests were performed to determine if there was a significant difference in overall and specific intraoperative event occurrence between the single ventricle and non-single ventricle groups. RESULTS: Average age and weight at the time of these surgical encounters was 4.86 years and 20.57 Kg. A majority of the surgical encounters were done in males (59.2%). Atrial septal defect was the most common type of CHD, and most of the patients in these surgical encounters received an ASA class of 3. Intraoperative events occurred in 24.4% of the surgical encounters with cardiovascular events being the most common (44.82% of total events). Other events made up 30.49% of events experienced intraoperatively, with respiratory events making up the remaining 24.70%. There was a significant difference in the occurrence of overall events between the single ventricle and non-single ventricle group (P<0.0001). Additionally, there was a significant difference in the occurrence of cardiovascular events (P<0.0001) and Other events (P=0.0001) between the single ventricle and non-single ventricle groups. There was no significant difference in the occurrence of respiratory events between the two groups (P=0.648). DISCUSSION: The most common type of intraoperative event experienced by CHD patients during a non-cardiac surgery was cardiovascular events. Significantly more overall intraoperative events, including cardiovascular and other events, occurred in surgical encounters performed on CHD patients exhibiting single ventricle physiology than those encounters done on CHD patients with a non-single ventricle physiology. Results of this study suggest that it would be likely for CHD patients to have a cardiovascular event occur during non-cardiac surgery and that this may be more likely in patients with a single ventricle physiology. This study was subjected to the limitations of retrospective chart review, as well as missing and infrequent documentation. Future analysis will look to find correlations between the occurrence of intraoperative events, and demographic and procedure variables analyzed in this study. / 2017-06-16T00:00:00Z

Several complications can be resulting from the neuraxial blockades, some of larger gravity, as the infections of the central nervous system, neurological lesions owed to spinal or epidural hematomas, toxicity due to the local anesthetics or direct trauma, and other less serious, as hypotension and bradycardia, even considered physiological. The goal of this research was to assess the intraoperative complications caused by the neuraxial blockades in patients 18 years of age or older not submitted to obstetrician procedures, during a period of 18 years, in a hospital with tertiary treatment – Hospital das Clínicas da Faculdade de Medicina de Botucatu – UNESP. Starting from the database (Microsoft Access) of the Anesthesiology Department, retrospective analysis was accomplished, from May 1990 to May 2008, of some of the complications related to the neuraxial anesthesias (spinal, continuous spinal, epidural, continuous epidural and combined spinal-epidural anesthesias). The found complications were: hypoxemia, hypoventilation, arterial hypertension, arterial hypotension, sinusal bradycardia and tachycardia, agitation, headache, convulsion, oliguria, vasovagal reaction, blockade failure, accidental perforation of the duramater, ventricular dysrhythmias, cardiac arrest and death. These were correlated with the anesthetic technique, physical state described by the American Society of Anesthesiology (ASA), age, sex and preoperative comorbidities, as arterial hypertension, atrial and ventricular dysrhythmias, obesity, diabetes mellitus, coronary artery disease, congestive heart failure,...

Participaram do estudo 33 indivíduos (63 terceiros molares), que se submeteram a TCMD na avaliação pré-operatória para exodontia dos terceiros molares inferiores inclusos. A TCMD foi utilizada na determinação da relação das raízes dos terceiros molares com o canal mandibular e do curso do canal mandibular. A exposição do nervo alveolar inferior (NAI) e a presença de hemorragia foram analisadas após a remoção do dente. Alteração neurossensorial do NAI foi avaliada após 7 dias. Achados clínicos e tomográficos foram comparados por meio do teste exato de Fischer (p<0,05). Foi observada relação estatisticamente significativa entre a exposição do NAI e a relação tomográfica entre as raízes dos terceiros molares e o canal mandibular (p=0,015). Todos os casos de alteração neurossensorial do NAI e hemorragia ocorreram quando as raízes do terceiro molar se apresentaram em relação de risco com o canal mandibular, porém a associação não foi estatisticamente significativa (p>0,05). Relação estatisticamente significativa foi encontrada entre o curso lingual do canal mandibular e a exposição do NAI (p=0,03). Portanto, a TCMD mostrou-se eficaz na determinação do risco cirúrgico para o feixe neurovascular alveolar inferior em exodontias de terceiros molares / Abstract: This study assessed the reliability of multidetector computed tomography (MDCT) in determining the surgical risk to the inferior alveolar nerve (IAN) in extractions of third molars. Our sample comprised thirty-three individuals (63 third molars) who underwent preoperative evaluation by MDCT before extraction of impacted mandibular third molars. MDCT was used to determine the relationship between the roots of the third molars and the mandibular canal and the course of the mandibular canal. IAN exposure and the presence of hemorrhage were analyzed after removal of the teeth. IAN neurosensory deficit was recorded after 7 days. Clinical and MDCT findings were compared using Fisher's exact test (p<0,05). There was a statistically significant association between IAN exposure and the tomographic relationship between the roots of third molars and the mandibular canal (p=0,015). All cases of IAN neurosensory deficit and hemorrhage occurred when the roots of the third molar presented in an at-risk relationship with the mandibular canal, however these associations were not statistically significant (p>0,05). A statistically significant association was found between the lingual course of the mandibular canal and IAN exposure (p=0,03). Thus, MDCT is effective in determining the surgical risk to the IAN bundle in extraction of mandibular third molars / Mestrado / Radiologia Odontologica / Mestre em Radiologia Odontológica

A introdução dos endoscópios na otorrinolaringologia determinou um grande avanço tecnológico, permitindo a sistematização da cirurgia endoscópica nasossinusal funcional. A possibilidade de trabalhar nos limites das cavidades nasossinusais com boa iluminação e visibilidade permitiu a expansão dessa cirurgia para abordar lesões da base do crânio e no interior da cavidade craniana, ampliando consideravelmente as suas indicações e a gravidade das suas complicações. Dentre estas complicações as lesões vasculares e ou de nervos cranianos estão entre as principais causas de morbidade. A artéria frontobasilar medial (AFM) é o primeiro ramo cortical do segmento pós-comunicante da artéria cerebral anterior e possui percurso próximo a base anterior do crânio. Havendo penetração intracraniana através da base anterior do crânio, durante uma cirurgia endoscópica endonasal, a AFM pode ser lesionada causando graves complicações. O objetivo deste estudo foi analisar as relações da AFM com a base anterior do crânio e reparos anatômicos utilizados em cirurgia endonasal, através de imagens obtidas por angiotomografia de crânio. E também identificar os locais de maior proximidade da AFM com a base anterior do crânio, sugerindo áreas de maior risco de lesão em cirurgia endonasal. Foram analisados 52 exames de angiotomografia de crânio, realizados no período de 2013 a 2015. O software OsiriXÒ foi utilizado para fazer as medições entre a AFM e os pontos de referência nos planos sagital e coronal, na ordem cronológica em que os exames foram coletados. A AFM descreveu um trajeto descendente, próximo a linha média (distancia média de 1,5 mm), se aproximando do plano esfenoidal (distancia média de 1,8 mm) e depois um trajeto ascendente à medida que se dirige para porção anterior do crânio, com distância média de 4,4mm na região da parede anterior do seio esfenoidal e de 12mm na região onde se encontra a artéria etmoidal anterior. Considerando o ângulo de trabalho na cirurgia endonasal e a os locais de maior proximidade da AFM com a base anterior do crânio, as regiões do etmoide posterior e plano esfenoidal foram as áreas de maior risco de sua lesão Study of the relations between medial orbitofrontal artery and anterior skull base performed by computed tomography angiography / The introduction of endoscopes in otolaryngology determined a great technological advance, allowing the systematization of the endoscopic endonasal sinus surgery. The possibility of working at the nasal cavity boundaries with good illumination and visibility allowed the expansion of this surgery to address lesions of the skull base and inside the cranial cavity, considerably broadening its indications and the severity of its complications. Among these complications, vascular lesions and cranial nerves are among the main causes of morbidity. The medial orbitofrontal artery (MOFA) the first cortical branch of the post-communicating segment of the anterior cerebral artery and has a path near the anterior skull base. If there is an intracranial penetration through the anterior skull base, during endonasal surgery, the MOFA can be injured causing serious complications. The objective of this study was to analyze the MOFA relations with the anterior skull base and anatomical repairs used in endonasal surgery, through images obtained by computed tomography angiography. And also identify the sites of greater proximity of the MOFA with the anterior skull base, suggesting areas of greater risk of injury in endonasal surgery. It was studied 52 examinations of skull computed tomography angiography performed between 2013 and 2015. The OsiriXÒ software was used to make the measurements between the MOFA and the reference points in the sagittal and coronal planes, in the chronological order in which the exams were collected. The MOFA described a descending path, close to the midline (average distance of 1.5 mm), approaching the sphenoid plane (average distance of 1.8 mm) and then an ascending path as it is directed towards the anterior portion of the skull, with an average distance of 4.4 mm in the region of the anterior wall of the sphenoid sinus and 12 mm in the region where the anterior ethmoid artery is located. Considering the angle of work in endonasal surgery and the places of greater proximity of the MOFA with the anterior skull base, the regions of the posterior ethmoid and sphenoid plane were the areas of greatest risk of its lesion
