title: Transcatheter closure of a pulmonary arteriovenous malformation in a patient with hereditary hemorrhagic telangiectasia.
abstract: Pulmonary arteriovenous malformations (PAVM) are rare pulmonary vascular anomalies. Over 50 % of the cases are associated with hereditary hemorrhagic telangiectasia or Osler-Weber-Rendu Syndrome. Untreated PAVMs progressively enlarge and can cause significant right-to-left shunting. Surgical- and catheter-based approaches have been used in the management of PAVM. We report a case of a 74-year-old man who presented with dyspnea and hypoxia and was found to have a large right-sided PAVM. He underwent percutaneous closure of the PAVM with an Amplatzer device with significant improvement of his symptoms.
