We experienced one case of surgical treatment of A-V fistula between the right common iliac artery and the right common iliac vein after lumbar laminectomy. The average vascular surgeon does not have extensive experience with this disorder owing to its rarity. Arteriovenous fistula of the aorta and its major branches present an unparalleled challenge in patient care. Because of their central location, blood flow through these fistulas may be massive;the associated complications are usually dramatic, resulting in severe refractory congestive heart failure, massive venous hypertension, or extensive hemorrhage during an illfated surgical repair.For this reason, it behooves one to become well acquainted with the problem in order to avoid morbid complications and thus ensure optimal patient care.
