Inferior vena cava (IVC) is mostly located at the right side of abdominal aorta. IVC anomalies may develop because of the complex embryogenesis and anastomosis of the paired abdominal veins. The persistent left supracardinal vein anastomoses with the right subcardinal vein which form the left-sided IVC crossing over the abdominal aorta. In that case, the left-sided IVC usually crosses anterior to the abdominal aorta after receiving left renal vein to join its retrohepatic position. The incidence of left sided IVC is reported as 0.2 and 0.5%.

Material Method

During routine dissection in the Department of Anatomy, Marmara University the left-sided IVC variation was encountered in a male cadaver aged 72.


The left-sided IVC was originated by confluence of the common iliac veins at the L5 vertebra level and ascended vertically to the level of the left kidney. Here, left-sided IVC received left testicular vein, bifurcated left renal vein, left first lumbar vein and left superior suprarenal vein. After crossing the abdominal aorta below the superior mesenteric artery, the IVC positioned to the right side of the aorta, it collected a common trunk that formed by the right testicular vein, the right first lumbar vein and the posterior segment of right renal vein. After receiving the right renal vein, the IVC then coursed in its normal retrohepatic position. Before reaching to the level of the left kidney, the left-sided IVC was crossed anteriorly by the left common iliac artery, the left testicular artery and the superior mesenteric artery, consecutively. Beside variations of tributaries of the IVC, additional hepatic artery which arose from superior mesenteric artery was present. Because of IVC variation the inferior pole of the right kidney was located 18mm higher than the inferior pole of the left kidney.


This case report showed the anatomy of left sided IVC and variation of its tributaries. Because of IVC variation, kidneys and arterial vessels were also variative.
