Abstract

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.

Keywords: Osler–Weber–Rendau; Stroke; hereditary hemorrhagic telangiectasia; pulmonary angiography; pulmonary arteriovenous malformation.
