Correction of symptomatic vascular steal distal to an arteriovenous fistula requires either fistula ligation or banding. Ligation carries the obvious disadvantage of destruction of a functioning angioaccess, whereas banding procedures have been plagued by the complexity of many of the reported techniques and by the difficulty of balancing fistula flow with distal perfusion. In this study a simple plication technique is described that avoids the introduction of any additional foreign material and that quantifies distal perfusion by means of intraoperative pulse volume recordings. Five patients have been treated by this method, two with autologous vein fistulas and three with bridge fistulas using polytetra fluorethylene. All five have had resolution of their ischemic symptoms with an increase in intraoperative pulse volume recordings of 5 mm or more. Only three of the patients had restoration of the radial pulse, which was not a specific end point of the banding procedure. Furthermore, all fistulas remained patent for at least 6 months and continued to provide adequate flows for hemodialysis. Banding/plication is clearly preferable to fistula closure for the management of steal syndrome. The method described herein is simple and hemodynamically identifies the minimal constriction that will resolve symptoms and preserve fistula flow.
