A Case of Double Inferior Venae Cavae
男性人體重複下腔靜脈之一例
摘要
高雄醫學院解剖學科今（85）年6月間大體解剖學實驗時，發現一例男性重複下腔靜脈的人體，這是從67年至85年之間，252解剖案例所發現的第一例此種異常。從比較解剖學與胚胎學的觀點，人體腰部的正常下腔靜脈是由胎生的右側主上靜脈發育而成，重複下腔靜脈的發生是由於左側主上靜脈的殘留與右側主上靜脈一同發育成為兩側下腔靜脈，至於左側下腔靜脈的案例是指右側下腔靜脈缺如者。本例重複下腔靜脈的兩側下腔靜脈有交通枝（骼間靜脈），在文獻上比沒有交通枝者較為多見。

In this study, we present a case of double inferior venae cavae found among 252 Taiwanese cadavers that were dissected in the gross anatomy laboratory of Kaohsiung Medical College from 1978 to 1996. The lumbar portion of the normal Inferior vena cava Is embryologically formed by the persistence of the right supracardinal vein. Persistence of the left one gives rise to the left inferior vena cava and the persistence of the bilateral ones, the double Inferior venae cavae. In this case, there is an anastomosis between the right and left inferior venae cavae. The anastomotic type of this anomaly seems to be more common than the non-anastomotic one.
