Rivaroxaban can be an attractive alternative for the treatment of cancer-associated thrombosis.

Objective To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein.Methods Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies.Results In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients.Conclusion Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.

Objective: Iliocaval obstruction is associated with venous hypertension symptoms and may predispose to deep venous thrombosis (DVT). Ultrasonography may fail to achieve noninvasive diagnosis of these obstructions. The possibility of using Computed Tomography Venography (CTV) for these diagnoses is under investigation. Methods: Patients with CVI graded at CEAP clinical classes 3 to 6 and previous treatment failure underwent evaluation with CTV. Percentage obstruction was rated by two independent examiners. Obstruction prevalence and its associations with risk factors and CEAP classification were analyzed. Results: A total of 112 limbs were prospectively evaluated. Mean patient age was 55.8 years and 75.4% were women. Obstructions involved the left lower limb in 71.8% of cases and 35.8% of patients reported a medical history of deep venous thrombosis. Overall, 57.1% of imaging studies demonstrated venous obstruction of at least 50% and 10.7% showed obstruction of >80%. The only risk factor that was found to be independently associated with a significantly higher incidence of >50% venous obstruction was a medical history of DVT (p=0.035) (Fisher' s exact test). There was a positive relationship between clinical classification (CEAP) and degree of venous obstruction in the limbs studied (Chi-square test for linear trend; p=0.011). Conclusion: Patients with advanced CVI are often affected by obstructions in the iliocaval venous territory and CTV is able to diagnose the degree of obstruction. There is a positive association between degree of obstruction and both previous history of DVT and severity of symptoms of CVI. ResumoObjetivo: A obstrução ilíaco-cava é associada a sintomas de hipertensão venosa e é um fator de risco para a trombose venosa profunda (TVP). A ultrassonografia pode falhar em seu diagnóstico. Não existe método de "sreening" bem estabelecido. A capacidade da Angiotomografia em realizar esse diagnóstico vem sendo investigada. Método: Pacientes portadores de IVC avançada e com falha no tratamento clínico foram submetidos à Angiotomografia. As imagens foram classificadas quanto ao grau de obstrução por dois investigadores independentes. Foram avaliados a prevalência e o grau de obstrução, e a sua relação com dados demográficos, fatores de risco e sintomas clínicos (CEAP). Resultados: Foram avaliados 112 membros. A idade média dos pacientes foi de 55,8 anos e 75,4% eram mulheres. A obstrução acometia o membro inferior esquerdo em 71,8% e havia história de TVP em 35,8% destes. Em 57,1% dos membros, havia obstrução > 50% e, em 10,7%, a obstrução era > 80%. A história de TVP foi o único fator demográfico com associação positiva com o grau de obstrução (p = 0,035) (teste Exato de Fisher). Houve associação positiva entre a classificação clínica (CEAP) e o grau de obstrução venosa (Teste Qui-quadrado para tendência linear; p=0,011). Conclusão: Pacientes portadores de IVC avançada são frequentemente acometidos por obstrução venosa ilíaco-cava e a Angiotomografia é capaz de identificar o grau dessa obstrução. Exi...

We report a case of inferior vena cava filter perforation immediately after filter implantation, recognized intraoperatively in a patient undergoing laparotomy for resection of locally advanced ovarian cancer. We describe an alternative approach with strut resection, less invasive than filter removal, enabling the device to be maintained and bleeding to be controlled.
