Study of Variations in the Origin of Obturator Artery

Abstract

Introduction: Obturator artery is the branch of anterior division of internal iliac artery. Variations in its origin are quite common and are very important from surgical point of view. Methods: To study the variations in the origin of the obturator artery 35 dissected vessels were studied. Results: Commonest variation of its origin from the posterior division of internal iliac artery was found in five cases. Other variations like its origin from internal pudendal artery or from inferior gluteal artery were also found, which are also discussed along with its embryological basis and clinical significance. Conclusions: Knowledge of anomalous origin of obturator artery from posterior division is helpful to vascular surgeons while planning endovascular treatment.
