Trifurcation of Posterior Division of Internal Iliac Artery: A Case Report

Abstract

Internal Iliac Artery has a large territory of distribution like all pelvic viscera, Gluteal region and the posterior & antero medial compartments of thigh through its visceral and parietal branches. The rare variation in the branching pattern of posterior division of Internal Iliac Artery was noted during routine cadaveric dissection of pelvic region for first year medical undergraduates in a 60 year old male cadaver. Knowledge of the variations of Internal Iliac Artery may be of use to the radiologists and also to the surgeons to avoid accidental hemorrhage during pelvic surgeries.

Clinical importance of a star shaped branch of internal iliac artery and unusual branches of an abnormal obturator artery: rare vascular variations

“…9 In yet another instance of variation, a case of trifurcation of the posterior division of internal iliac artery was reported, in which the posterior division gave rise to the LSA, the SGA and a common trunk. 10 …”
