Aberrant Supply of the Common Penile Artery from an Inferior Epigastric/External Pudendal Artery Trunk: Radiological and Urological Implications

Abstract

In cases of arteriogenic impotence, penile angiography is often performed before penile revascularization. Evaluation of the inferior epigastric arteries is critical for preoperative planning, for use of the dominant vessel is preferred. Performance of penile angiography requires knowledge of the extensive variations of the penile arterial system. This case report describes an anatomical variation of both the inferior epigastric artery and the penile arteries. Failure to recognize this variation could have resulted in a failed penile revascularization if surgery had been performed.
