Pulmonary arteriovenous fistula is a condition in which an abnormal connection (fistula) develops between an artery and vein in the lungs. As a result, blood passes through the lungs without receiving enough oxygen.

What are the symptoms of Pulmonary arteriovenous fistula?

What causes Pulmonary arteriovenous fistula?

Pulmonary arteriovenous fistulas are usually the result of a genetic (inherited) disease that causes the blood vessels of the lung to develop abnormally. Fistulas also can be a complication of liver disease.

Patients with Rendu-Osler-Weber disease (ROWD) -- also called hereditary hemorrhagic telangiectasis (HHT) -- often have abnormal blood vessels in many parts of the body.
