Leg Ulcer as a Complication of a Posttraumatic Tibial Arteriovenous Fistula Treated by Endovascular Approach With Stent-Graft Placement

Abstract

Endovascular treatment of posttraumatic arteriovenous fistulae (AVFs) in the lower extremities by means of covered stent-grafts is widely accepted, and many cases have been reported in the iliac-femoral region. However, few reports exist on the treatment of infrapopliteal AVFs, with or without a pseudoaneurysm, using this method. The authors present this case report dealing with a patient who had undergone a tibial and peroneal open fracture in his left limb 34 years ago. He developed a leg ulcer as a consequence of AVF between the tibialis posterior artery and vein, which resulted in venous insufficiency, which was treated by the endovascular approach with the placement of a stent-graft. Total healing was achieved over a period of 3 months. Angio-CT was performed, showing stent-graft patency 6 months after the endovascular procedure.
