On dissection of the abdomen of an adult male cadaver, in addition to the normal inferior vena cava on the right side, an unusual venous channel which connected the left renal vein with the left common iliac vein was found; (probably the left inferior vena cava). The left testicular and the left suprarenal veins were opening into the left renal vein as usual. Other than this, a retrocaval ureter was found on the right side. The works of previous authors have highlighted the incidence of a venacaval duplication and its surgical implications, but here, we are presenting a unique case of a double inferior vena cava with an anomalous retrocaval ureter. A conglomeration of such vascular malformations is of immense surgical importance, and it is indicative of a grossly defective angiogenesis. Keeping in mind the clinical relevance of the variations which were observed, an attempt was made to explain them in the light of the embryogenic development.
在解剖一具成年男性尸体的腹部时，除了右侧正常的下腔静脉外，还发现了一条将左肾静脉与左髂总静脉相连的异常静脉通道；（可能是左位下腔静脉）。左睾丸静脉和左肾上腺静脉像往常一样汇入左肾静脉。除此之外，右侧发现了腔静脉后输尿管。先前作者的研究强调了腔静脉重复畸形的发生率及其手术意义，但在此，我们呈现了一例伴有异常腔静脉后输尿管的双下腔静脉独特病例。这种血管畸形的聚集具有极大的手术重要性，并且表明血管生成存在严重缺陷。鉴于观察到的变异的临床相关性，我们尝试根据胚胎发育来解释它们。
