Inferior vena cava (IVC) variations signify predisposition to deep vein thrombosis and may complicate retroperitoneal surgeries including abdominal aortic surgery and nephrectomy. Failure to recognize such variations may predispose the patient to life‐threatening complications. Despite their clinical significance, few studies have detailed variations from direct observation. This study assessed 36 cadavers for variations of the IVC and left renal vein. Prevalence was determined for the following variations: double IVC, isolated left IVC, retroaortic left renal vein, and circumaortic renal vein. Two of the 36 cadavers (5.6%) were variant. The variations included a double IVC (1:36; 2.8%) and a retroaortic left renal vein (1:35; 2.9%). There were no occurrences of an isolated left IVC or a circumaortic renal vein (0:36; 0% and 0:35; 0%, respectively). Further, the double IVC and the retroaortic left renal vein were accompanied by regional pathologies—both having kidney pathology and one with an abdominal aortic aneurysm. The results of this study suggest that, IVC variations are rare and, when an IVC variation is discovered, there is typically an attending urinary system pathology.
