Objetivo: Avaliar o impacto de fatores de risco no desenvolvimento de eventos tromboembólicos em pacientes com lesão medular. Métodos: Estudo observacional, prospectivo e cruzado. Pacientes elegíveis (n=100) tinham lesão medular por trauma raquimedular e mais de 18 anos. O grau de lesão sensorial e motora foi avaliado com base na escala ASIA (ASIA Impairment Scale - AIS). Amostras de sangue foram coletadas para exames de coagulação, hemogramas, análises bioquímicas e laboratoriais. Exames de ultrassonografia foram realizados nos sistemas venosos superficial e profundo dos membros inferiores. Experimentos de PCR em tempo real foram realizados com o intuito de investigar mutações nos genes da protrombina (G20210A) e do fator V de Leiden (G1691A). Resultados: O principal achado deste estudo foi a maior ocorrência de Trombose Venosa Profunda (TVP) em pacientes com fator V de Leiden e hiperhomocisteinemia. Não houve associação entre Lesão Medular por TVP, Tromboembolismo Venoso (TEV) e trombofilia. Não houve também relação com lúpus anticoagulante e anti-cardiolipina. Conclusões: Houve importante diferença na incidência de TVP em pacientes com Lesão Medular, tanto aguda quanto crônica (após um ano da lesão). A investigação de trombofilia deve ter como base os fatores clínicos, fatores de risco para TVP e história familiar de trombose / Objective: Evaluate the impact of risk factors in the development of thromboembolic events in patients with spinal cord injury. Design: Observational, prospective and cross study. Eligible patients (n=100) had spinal injury (SI) by spinal cord injury (SCI), older than 18 years of age. The degree of motor and sensory lesion was evaluated based on ASIA Impairment Scale (AIS). Blood samples were collected for coagulation exams, hemogram, laboratory and biochemical analyses. Ultrasonography analyzes were performed from deep and superficial venous systems of lower limbs. Quantitative real-time PCR experiments were performed in order to investigate mutations in the prothrombin (G20210A) and Leiden factor V (G1691A) genes. Results: The main finding of this study was the higher occurrence of Deep Venous Thromboembolism (DVT) in patients with Leiden factor V and hyper homocysteinemia. There was no association between SI for DVT, venous thromboembolism (VT) and thrombophilia. Also, there was no relation between lupus anticoagulant and anti-cardiolipin. Conclusions: There is an important difference in the incidence of DVT in patients with SI by acute SCI and after 1 year. The conduct of the investigation for thrombophilia should be based on clinical factors, risk factors for DVT and family history of thrombosis

Trombophilia means an increased disposition to creation of trombs. Health complication incurred as a consequence of hypercoagulation can be very serious. When a trombophilic mutation is found at a patient, it brings necassity of thrombosis - control in risk situations (e.g. pregnancy, operation) for the rest of the patient's life. There were filed 300 people (206 women and 94 men) with trombophilic mutations into my study of clinical signification of trombophilic mutations. These people were examinated in years 2008 - 2010. Most of positive medical findings - 266 people, were recorded in the area of MTHFR (C677T i A1298C) mutations. There were less findings in the field of FV Leiden and FII prothrombin mutations. Multipath trombophilic mutations were found at 99 patients. I accordance with foreign literature, our results advert to clinical consequences of trombophilic mutations like: repeated spontanious aborts, cerebrovascular akcident (CA), ischaemic heart disease (IHD), thrombosis, flebothrombosis, pulmonary embolism, varicose veins, aseptic necrosis of hip bone, arterial sclerosis and aortic stenosis. Mutations MTHFR C677T and MTHFR A1298C we found mainly at patients with CA, IM and IHD. Leiden mutation was most often found at patients with thrombosis, flebothrombosis and pulmonary embolism. We...
