When a patient needs an arteriovenous endovascular fistula, the doctor will give a short talk about the basic method of the procedure and exactly how it is done. The artery is surgically separated out, the vein is also surgically separated up, an end-to-end or end-to-side anastomosis is taken, the vessels of the artery and vein are cut off, and an opening is made above the arterial blood vessel so that the blood flow from the artery and the vein are connected together, so that the blood from the artery goes in the direction of the vein. In this way after the operation we can feel the tremor, what does it mean. That is, the arterial blood has flowed to the vein, and this is the arteriovenous endovascular procedure. First of all there are many choices of vessels, the more common standard choice of endovascular is the cephalic vein and the radial artery, which is our forearm. If the vascular condition is poor, the doctor may recommend doing for example the brachial artery or the median vein, choosing a different vessel because the condition of the vessel determines the procedure. When there is no autologous vessel, then the doctor may recommend an artificial vessel, which is called an autologous arteriovenous endovascular fistula and an arteriovenous endovascular fistula with artificial vessels.
