An arteriovenous endovascular fistula is the connection of a vein to an artery so that the arterial blood flows inside the venous vessel and the venous blood develops and arterializes in the presence of an artery. When an arteriovenous endovascular fistula is performed, the goal is to allow the developing vein to be punctured for use by dialysis patients. Because of the relatively thin walls of the natural veins, the flow is not sufficient for dialysis applications. After the creation of the arteriovenous endovascular fistula, the arterial blood is transferred to the veins, the walls of the veins become thicker and the flow inside the veins increases. With the guaranteed blood flow, the blood is drawn out through the blood flow to the dialysis machine and then returned to the patient’s body. This so-called lifeline, through the arteriovenous endovascular fistula, allows the patient to have guaranteed access to dialysis. Therefore, arteriovenous endovascular fistulas are very important for some patients with renal failure, also known as ckd-5 stage, who are on hemodialysis. If the endovenous fistula is well maintained, the patient’s hemodialysis will be more adequate and the patient’s quality of life will be greatly improved. If the arteriovenous endovascular fistula is faulty, the dialysis will be faulty, and if the toxins in the patient’s body are not removed in a timely manner, the resulting problems can be very serious and can even seriously affect the patient’s life. Therefore, as a vascular surgeon or a hemodialysis access physician, it is important to establish an arteriovenous endovascular fistula as a very important thing to accomplish. If the patient is able to establish a good arteriovenous endovascular fistula from the beginning, it will be helpful for the subsequent treatment.
