Looped External Iliac Artery: a Case Report

Abstract

SUMMARY:Variations of the external iliac artery are very rare. We found a rare variation in the left external iliac artery. The artery was long and formed a characteristic loop. The loop was found in the lesser pelvis in close relation to the obturator nerve. This loop may compress obturator nerve and vessels. The knowledge of this loop might be important for gynaecologists, orthopaedic surgeons and urologists since it may be involved in surgeries of hip, ovary and prostate.

Anatomic variability of branches of iliac and femoral arteries in human fetuses

“…The persistent sciatic artery that replaces the femoral artery is an anomaly difficult to diagnose, leading to ischemia of the lower extremity 7,[10][11][12][13] . The resources contain data of topographic variants of the accompanying artery of sciatic nerve [14][15][16][17] . Clinical observation of a patient with abnormal course of iliac and femoral arteries is reported by Tsygankov et al 13 .…”
