Abstract

The knowledge of vascular variations like other anatomical ones, is important during the operative, diagnostic, and endovascular procedures in abdomen. This report describes multiple variations in the abdominal vessels as found in the cadaver of 50-year-old Korean man during educational cadaveric dissection in the department of anatomy. The variations found were; double inferior vena cava, the left internal iliac vein peculiar joining to right inferior vena cava, left external iliac vein directly connected to left inferior vena cava, two left renal veins opening separately into left inferior vena cava, termination of left testicular vein into lower left renal vein, the right testicular vein opening into the right renal vein, high level of the aortic bifurcation and high bifurcation level of the common iliac arteries. Although, other variations reported in this case exist as individual variations, the existence of the multiple variation of them is extremely rare. It is important to know the variations of abdominal vasculature for the success of surgical operations and radiological investigations of those regions.
