Congenital anomalies of the inferior vena cava are a relatively rare pathology, usually with an asymptomatic iter. They are usually diagnosed by chance during surgery on the aorta or retroperitoneal structures. From bioptic material their incidence is estimated to be 2-3% and the percentage of intraoperative findings varies in different series between 0.2 and 0.6%. Of the various kinds of anomaly, caval duplication and a left-positioned vena cava are those most commonly found. The recent report of a case of a malpositioned vena cava and iliac veins prompted us to re-examine the literature and revise our series of cases.
下腔静脉先天性异常是一种相对罕见的病理情况，通常病程无症状。它们通常在对主动脉或腹膜后结构进行手术时偶然被诊断出来。根据活检材料估计其发生率为2% - 3%，不同系列中术中发现的百分比在0.2%至0.6%之间变化。在各种异常类型中，腔静脉重复和腔静脉左位是最常见的。最近一例腔静脉和髂静脉位置异常病例的报告促使我们重新审视文献并修订我们的病例系列。
