Persistent left superior vena cava is encountered in about 0.3 to 0.4% of human beings. It derives from remnants of the left cardinal vein system. This results in either a duplication of the superior vena cava or in a single left vena cava. The diagnosis is easy in case of associated cardiovascular anomalies. Two cases of single left vena cava and one case of duplication of the superior vena cava are described. All were identified owing to repeatedly aberrant courses of central venous catheters. Diagnosis was easily provided by angiography. Clinical course was uneventful. Despite its usual good tolerance, the persistence of a left vena cava, as an isolated anomaly, must not be neglected as it carries many practical implications which are reviewed.
在大约0.3%至0.4%的人群中会出现永存左上腔静脉。它源于左主静脉系统的残余部分。这会导致上腔静脉重复或出现单一的左腔静脉。在伴有心血管异常的情况下，诊断较为容易。本文描述了两例单一左腔静脉病例和一例上腔静脉重复病例。所有病例均因中心静脉导管反复出现异常走行而得以确诊。血管造影可轻松做出诊断。临床过程平稳。尽管通常耐受性良好，但作为一种孤立的异常情况，左腔静脉的存在不可忽视，因为它具有许多实际影响，本文对此进行了综述。
