An arteriovenous fistula (AVF) is an abnormal connection between a vein and an artery. Generally, the blood flows from the arteries to the capillaries to the veins. Nutrients and oxygen in the blood travel from capillaries to tissues in the body.
With the AVF, blood flows directly from an artery into a vein, bypassing some capillaries. In this condition, tissues below the bypassed capillaries receive diminished blood supply. AVF commonly occur in the legs, but may develop anywhere in the body. Untreated arteriovenous fistula leads to serious complications.

Cardiac catheterization- An arteriovenous fistula may occur due to the complication of a procedure called cardiac catheterization. During the cardiac catheterization procedure, a long and thin tube is inserted in an artery in the groin, arm or neck and threaded through the blood vessels to your heart.
If the needle which is used in catheterization crosses an artery during the procedure and the artery is widened, can create an arteriovenous fistula.
Injuries that pierce the skin- arteriovenous fistula may also occur after a piercing injury like a gunshot or stab wound.
Genetic condition- arteriovenous fistulas in the lungs can also be occurred due to a genetic disease that causes blood vessels to develop abnormally throughout your body.
