SUMMARY: A case of a left sided inferior vena cava (IVC) along with other anatomical vessel variations in an 87-year-old Japanese male cadaver is reported.
The left sided IVC, which was formed by confluence of the common iliac veins behind the left common iliac artery at the level of the fifth lumbar vertebra, ascended vertically along the left side of the vertebral column and the abdominal aorta. It passed upward to receive a left testicular vein and two left renal veins which crossed. After receiving the left renal veins, the left sided IVC passed obliquely upward to the right of the vertebral column to receive the left suprarenal vein. At the right side of the abdominal aorta, the oblique part received the common stem of the second lumbar vein, which crossed behind the testicular artery, and a vein from paraaortic lymph nodes. Then, it received the right renal vein with the right testicular vein. The remainder of the caval pathway assumed its normal position to the right of the aorta. We consider that the above mentioned anomaly of the IVC is formed by the persistence of the left supracardinal vein and the disappearance of the right one. The present case belongs to Type 2 of the classification of Yoshida et al.(1981). In the present study, we discussed the formation of the anomalous variations and clinical symptoms.
