Dialysis Fistula is the most popular dialysis for anyone who suffers from renal failure. We know that removing waste products from the blood and restoring water or chemical balance are the kidneys’ main functions of kidneys. The most crucial decision for kidney failure patients is to choose what type of vascular access which they will use for kidney dialysis. Vascular access means what method is adopted to couple the hemodialysis machine to the blood supply. As we know vascular access is very important, the ability and efficiency to access an artery or a vein determines if a kidney failure patient will die or live. Dialysis fistulas one of 3 main means of vascular access is the most common way because of fewer complications.
What is a dialysis fistula?
A fistula is created by surgery, connecting an artery and a vein. It is also called arteriovenous fistula or an AV fistula for short. AV Fistulas are constructed to join a vein to an artery. The procedure can make the vein become “stronger and larger”, which can make repeated needle insertions for dialysis treatment much easier. Normally, patients will receive needle sticks parecchio times per week.
The surgery schedule
Once the decision for hemodialysis is made, fistulas preparation should be started quickly, or it will become worse. First do some tests to find the right location for the fistulas. Use ultrasonic technology to draw a roadmap of the arteries and veins and measure the blood through each of them. Then select the best qualified blood vessels, general or local anesthesia. The whole surgery spends a few hours. After surgery, do some pertinence of exercise to strengthen the fistula is highly recommended by doctors. Three weeks after the surgery, when the surgical incision starts to heal, and the fistulas begin to mature. This process may take about 3 to 6 months, even to 24 months. If the arteriovenous fistula may fail to mature, other alternative method must take into account. Before complete maturation, a temporary alternative access point must be used.
Dialysis Fistulas have none of the frequent complications which are caused by grafts, because they are less prone to infection and more durable. Grafts may frequently lead to be clogged when clots form in the tubing. And they are prone to be infected. In 2005, the Centers for Medicare and Medicaid Services launched an initiative called “Fistulas First”. Arteriovenous fistula have been clinically proven that they can maximum the volume of blood filtered, shortening the treatment sessions. Statistics have shown the increasing number of patients with dialysis fistula.
Although AV fistula is effective, not anyone who needs kidney dialysis is suitable for dialysis fistula. The patients with a history of small veins, artery diseases or reduced circulations may not be suitable for fistulas because of increasing the risk of side effects and limiting blood flow to that area. So before surgery, related tests must be done to determine whether the veins large or strong enough to support the placement of the dialysis fistula. Dialysis Fistula complications maybe include clotting, narrowing of the fistulas, aneurysm formation, excessive bleeding and infection.
