What Is Arteriovenous and Aneurysmal Fistula?

An arteriovenous fistula, or AVF, is an abnormal connection of vessels between an artery and a vein. Generally, people suffering from renal failure and undergoing long-term hemodialysis require a surgical creation of an AV fistula for smooth dialysis. However, these fistulas can also arise when an aneurysmal artery ruptures into an adjacent vein. This is called an aneurysmal fistula, where intimal, medial, and adventitial layers of the vessel wall expand to a diameter of 18mm, causing pain and disturbance in blood flow. No medication or lifestyle changes can cure a fistula. Surgery is usually necessary.

Most fistulas heal by themselves. However, some high-risk and complicated ones may require surgeries.

Although AV fistula surgeries are safe, it is, however, beneficial to consider risks that affect the patient like Hemorrhaging, low venous flow or hematomas, Venous Hypertension, and Ischemia. Our providers will discuss all the risks and what is best for you - after all, every patient is different.

Recovery rate and success of surgeries depend on the health of the patient, the type of fistula, and the skill of the surgeon.
