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.
The main objective of AV fistula treatment is to isolate and close the abnormal connection, thereby attempting to maintain normal blood flow.

Depending upon their etiology, AV fistulas are broadly divided into two groups:
Congenital fistulas are generally rare. They occur as a result of genetic factors or malformations. These include pulmonary, coronary, hepatic, carotid-cavernous, and dural fistulas.
Acquired AV Fistula is further sub-divided into:
Swelling in the arms or legs
Decreased blood pressure
Fatigue
Bulging, purplish veins seen through the skin, similar to varicose veins
Heart failure
Fingertips to spread out and become rounder than normal (clubbing)
Coughing up blood
Gastrointestinal (GI) bleeding
Pale gray or blue lips or fingernails due to lack of blood flow (cyanosis)
A fistula of any type can be scary and painful and can affect the daily life of a person.
