Resumo

Veia cava inferior dupla é uma variação anatômica rara cuja prevalência é de 0,2-3%. O implante de filtro de veia cava, quando indicado em casos com duplicidade da veia cava inferior, pode ser realizado de diferentes formas: em ambas as veias cavas; em uma delas, embolizando a anastomose entre ambas; em somente uma delas; ou por implante supra-renal. Relatamos um caso de trombose venosa profunda no pós-operatório de implante de prótese de quadril com contra-indicação para tratamento anticoagulante e cuja cavografia evidenciou duplicidade de veia cava inferior. O implante de filtro de veia cava inferior realizado em posição supra-renal mostrou-se opção adequada e segura.

Abstract

Double inferior vena cava is a rare anatomic variation with prevalence ranging between 0.2-3.0%. In cases of duplication, inferior vena cava filter placement options include placing it in both vena cava, coil-embolization of the intervenous segment plus placing a filter in the right inferior vena cava, or suprarenal filter placement. We report a case of deep venous thrombosis after unilateral primary total hip replacement, presenting with contraindications for anticoagulant therapy, in which cavography showed inferior vena cava duplication. Inferior vena cava filter placement was performed in the supra-renal portion and was proved to be an adequate and safe procedure.
