    Abstract:
    Hand ischemia is a rare complication of angioaccess surgery for hemodialysis. Management usually requires ligation of the arteriovenous fistula (AVF). The purpose of this report is to describe our experience with the use of the distal revascularization interval-ligation (DRIL) technique for treatment of ischemia without ligation of the AVF. From January 1999 to September 2002, the DRIL technique was used to treat 18 patients (10 men, 8 women, 10 diabetic patients) with severe paresthesia of the hand (n = 9) and finger necrosis (n = 10). The AVF was located at the elbow in 16 patients and at the wrist in 2 patients. Mean flow distal to the AVF was less than 10 mL in 5 patients, less than 5 mL in 10, and unmeasurable in 3. The conduit used for all DRIL arterial bypasses, including 15 brachiobrachial bypasses, 1 axillobrachial bypass, 1 brachioradial bypass, and 1 radioradial bypass, was the great saphenous vein graft. Trophic manifestations required finger amputation in five patients, pulpar necrosis resection in four, and transmetacarpal amputation of the index finger in one patient. Symptoms disappeared in 13 patients (73%) and improved in 5 (27%). The time required for healing of finger amputations and trophic manifestations ranged from 15 days to 2 months. Mean arterial flow through the DRIL bypass was 50 mL/min (range, 20-90 mL/min). With a mean follow-up interval of 16 months (range, 5-48 months), primary patency of the DRIL artery bypass and AVF was 94% and the limb salvage rate was 100%. The DRIL technique is the most effective procedure for treatment of angioaccess-induced hand ischemia. This technique can be used to achieve persistent relief of symptoms with continued access patency. The DRIL artery bypass improves vacularization of the hand, and ligature of the artery stops the vascular steal without affecting hemodialysis access. The DRIL technique should be proposed as first-line treatment for hand ischemia due to AVF for hemodialysis.
