Endovascular management of postthrombotic ilio-iliac arteriovenous fistula with occluded common iliac vein: A case report and literature review

Abstract

Chronic venous hypertension as a result of May—Thurner syndrome (MTS) and subsequent venous thrombosis is a frequently observed clinical condition. However, a postthrombotic arteriovenous fistula (AVF) is a phenomenon not reported commonly. Such conditions have been treated surgically and by endovascular approach — embolization or stenting. We present a case of concomitant MTS and pelvic AVF in a patient with recurrent deep vein thrombosis, who also had lumbar laminectomy in the past, resulting in massive and debilitating left lower extremity edema and bleeding varices in the left lateral thigh, which was successfully treated with the placement of stent graft/stent in both arterial and venous systems.
