This study reviews the clinical course of 22 patients with chronic renal failure on hemodialysis with ischemic or neurologic problems in the upper extremity distal to an arteriovenous fistula. Two-distinct presentations were observed. Twelve patients developed significant motor and/or sensory impairment immediately following surgical construction of the fistula. Ten patients presented with upper extremity ischemia, established or impending tissue loss, or nonhealing wounds distal to a dialysis fistula. Seventeen of the 22 patients were diabetic. Nerve conduction studies, noninvasive vascular studies, and arteriography were used to confirm the diagnosis. Sixteen of the 22 patients had ligation or revision of the fistula. Five patients underwent amputations at the metacarpal or phalangeal level, and one patient underwent below-elbow amputation.
