A 57-year-old male patient with hereditary hemorrhagic telangiectasia presented with an acute right middle cerebral artery ischemic stroke. Investigations revealed a right middle cerebral artery M2 occlusion, hypoxemia, and a large pulmonary arteriovenous malformation and right lower limb deep venous thrombosis. Closure of the pulmonary arteriovenous malformation was successfully performed with an Amplatzer device. Catheter closure of pulmonary arteriovenous malformations in patients with hereditary hemorrhagic telangiectasia is a recognized treatment modality to prevent recurrent ischemic stroke and other embolic and hemorrhagic complications.

D001164	Arteriovenous Fistula	An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.

D013683	Telangiectasia, Hereditary Hemorrhagic	An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.
