![]() This risk is estimated to be approximately 1% in AVF and between 4 and 5% in AVG (Goel et al. Excess shunting through the AVF can result in dialysis-access steal syndrome (DASS) leading to distal ischaemia or high-output cardiac failure when severe. Occasionally, synthetic polytetrafluoroethylene arteriovenous grafts (AVG) are utilised when there are no suitable veins to form an autologous conduit. Common AVF types encountered in practice include the radiocephalic, brachiocephalic and brachiobasilic fistulas (Vascular Access Work G 2006). Percutaneous AVF banding is a relatively straightforward and effective minimally-invasive technique for treatment of DASS supported by short-intermediate term data.Īrteriovenous fistulas (AVF) are the preferred method of vascular access for patients on chronic haemodialysis. The technique, selection of appropriate banding diameter for flow reduction, limitations and complications of alternative surgical techniques are discussed. However, clinical success was limited in one case due to underlying arterial insufficiency. Both cases were performed for DASS, with good technical success. ![]() ![]() Two representative cases from our local experience were selected to illustrate the technique in a stepwise manner. We review a case series of percutaneous AVF banding procedures for DASS and high-output cardiac failure to illustrate the technique and limitations of this technique. Percutaneous AVF banding is a minimally-invasive technique for treating DASS with good short-intermediate term results. However, excess shunting through the AVF can result in dialysis-access steal syndrome (DASS) or high-output cardiac failure. Arteriovenous fistulas (AVF) are the preferred method of vascular access for chronic haemodialysis. ![]()
