Coil Embolization as a Treatment Alternative for Dialysis-Associated Steal Syndrome

Abstract

Steal syndrome is a rare but serious complication of arteriovenous fistulas (AVF) created as well as the angioplasty technique used for its maturation and can have severe consequences if left untreated. Standard treatment options generally lead to loss of fistula access, although newer practices such as coil embolization are being utilized to conserve the AVF. Here we illustrate a case of a 65-year-old man with end-stage renal disease on dialysis, who had a Brescia-Cimino (radiocephalic) AV fistula created and subsequently underwent balloon-assisted maturation for an underdeveloped fistula. One month later, the patient presented with a cold thumb and index finger along with parasthesias in those digits and was treated with coil embolization of the distal radial artery while leaving the AVF functional. Steal syndrome and the novel treatment option of coil embolization are reviewed here.
