Duplicação da Veia Cava Inferior

Duplicação da Veia Cava Inferior

Abstract

Apresenta-se o caso de um doente do sexo masculino, com 83 anos de idade, que no decurso de investigação de quadro de suboclusão intestinal realizou uma tomografia axial computadorizada (TAC), que revelou a presença de duas veias cavas inferiores (setas brancas), unindo-se imediatamente na porção pré-hepática (variante do normal). Pode observar-se a artéria aorta, com calcificações, entre ambas as veias cavas inferiores. O desenvolvimento da veia cava ocorre entre a 6ª e 10ª semanas de gestação, a partir da veia supracardinal direita, enquanto que a veia supracardinal esquerda involui. A sua duplicação ocorre como resultado da persistência de ambas as veias supracardinais (direita e esquerda) e tem uma prevalência estimada de 0.2-0.3%. Geralmente, é uma anomalia assintomática, detectada acidentalmente em exames imagiológicos. Contudo, o seu diagnóstico é importante, uma vez que a sua presença tem implicações clínicas relevantes, nomeadamente no tratamento de doenças tromboembólicas.
