Vascular access surgery
This is a surgery that creates a connection between an artery and a vein in a patient's arm for dialysis. There are two types of vascular access:
Arterio- venous anastomosis
Arteriovenous fistula (AVF)

Tunneled cuffed catheter Semi- permanent vascular access
Synthetic bridge graft Blood to dialysis machine
For AVF and AVG, the surgeon connects an artery to a vein as access point in preparation for dialysis, making an incision on the non-dominant arm near the wrist or the elbow. For a tunneled cuffed catheter, surgery is done under local anesthesia and does not require hospitalization after surgery.
