An arteriovenous endovascular fistula procedure is performed by surgically combining neighboring arteries and veins to create a new blood flow pathway that can be easily punctured for hemodialysis treatment. The most commonly used vessel for arteriovenous endovascular fistulas is the radial artery-cephalic vein endovascular fistula in the wrist of the forearm. The arteriovenous endovascular fistula procedure begins with the disinfection of the corresponding vascular site and the use of local anesthesia. The radial artery and cephalic vein are separated by a 3-cm longitudinal incision down the corresponding vessel; the cephalic vein is closed proximally with vascular clamps, and the radial artery is ligated distally and closed with vascular clamps at both ends, and finally anastomosed. Because the pressure in the vein is too low and the flow rate is slow, the artery is deeper and more difficult to maneuver and cannot be reused. Patients who need hemodialysis treatment can take arteriovenous endovascular fistula surgery, this method combines the advantages of the two to establish hemodialysis access. Because the veins are connected to the arteries, causing increased blood flow and pressure in the veins, the venous vessels dilate to form arterialized blood vessels. It not only ensures sufficient blood for hemodialysis, but also provides sufficient safeguard for hemodialysis. Patients who need endovascular fistula surgery are recommended to visit regular hospitals in time and have the surgery done by professional doctors.
