Right external iliac vein (REIV) ascend as the dorsal right IVC (DRIVC) after giving a communicating branch (COM) which joins with right internal iliac vein (RIIV) to form right common iliac vein (RCIV). Larger ventral right IVC (VRIVC) is formed anterior to aortic bifurcation by the union of RCIV and left common iliac vein (LCIV). Right common iliac artery is pulled aside and Internal iliac artery is cut to show the formation of RCIV.
