Brief Summary

Arterio-arterial vascular access, Arterio-venous synthetic access, Venous hypertension, Hemodialysis patients Purpose: To describe a technique used to treat a patient with Lt upper limb synthetic arterio-venous vascular access and venous hypertension of the same limb. Technique: the investigator expose the venous anastomosis of the graft by small longitudinal incision in the axilla and dissection of the axillary artery just parallel to the axillary vein , the investigator disconnect the graft from the axillary vein and do primary repair of the vein , then the investigator do end to side anastomosis of the graft to the axillary artery , after finishing this anastomosis the axillary artery ligated just below the anastomosis. Conclusion: the conversion of arterio-venous graft to arterio-arterial vascular access in precious access with venous hypertension lead to resolution of edema of venous hypertension and preservation of access for dialysis.
