Conversion of Arterio-Venous Access of Hemodialysis to Arterio-Arterial Access for Treatment of Venous hypertension with Central Venous Occlusion.

This report describes conversion of arterio-venous graft or fistula to arterio-arterial vascular access as a new surgical treatment option for central venous occlusion. It starts with control of the axillary vein and the synthetic graft or superficialized vein proximally, the suture line of venous anastomosis is closed and end-to-side anastomosis of the synthetic graft or vein to the brachial artery (BA) is done, then ligation of the BA distal to the anastomosis is done. Now the blood flow is directed through synthetic graft or vein from proximal to distal BA that can be used as arterio-arterial vascular access for hemodialysis.
