What is fistula failure?
An AV fistula can fail when there is a narrowing, also called stenosis, in one of the vessels associated with the fistula. When a narrowing occurs, the volume and rate of blood flow can decrease, and you may be unable to dialyze adequately.
Who created the AV fistula?
The procedure was invented by doctors James Cimino and M. J. Brescia in 1966. Before the Cimino fistula was invented, access was through a Scribner shunt, which consisted of a Teflon tube with a needle at each end. Between treatments, the needles were left in place and the tube allowed blood flow to reduce clotting.

How do you unclog a fistula?
When fistulas and grafts become clogged or narrowed, which can prevent a patient from undergoing dialysis, interventional radiologists use image-guided interventions to fix the problem: Catheter-directed thrombolysis, which dissolves blood clots that build up in fistulas and grafts by injecting a medicine.
Can AV fistula be removed?

Where do aneurysms most commonly occur?
Aneurysms can occur anywhere throughout the circulatory system, but most commonly develop along the aorta (the body’s main artery that runs the length of the trunk from the heart) and in blood vessels of the brain. Aneurysms are potentially fatal if they rupture.
Where are aneurysms most commonly found?
The most common location of an aneurysm is the aorta, which carries oxygenated blood from the heart to the body. The thoracic aorta is the short segment of the aorta in the chest cavity. The abdominal aorta is the section of the aorta that runs through the abdomen.
