Percutaneous intervention for restoration of patency of occluded lower limb arteriovenous dialysis access

Both the patient underwent successful endovascular treatment for the failure of the lower limb AV dialysis access thrombosis and/or obstruction. One patient had minimal dye extravasation during manipulation of the guide wire, which ceased spontaneously. On follow-up, both patients maintained patency of the dialysis access and are undergoing successful hemodialysis. One patient had a recurrence of the thrombosis of the fistula at 9th month of the follow-up. Endovascular treatment was tried but we could not succeed. However, we found endovascular treatment safe and effective in treating AV fistula failures.
