Percutaneous closure of a giant pulmonary arteriovenous malformation using multiple devices.

Percutaneous device closure is an established method to treat pulmonary arteriovenous malformation (PAVM). This report describes the case of a 23-year-old man with hereditary hemorrhagic telangiectasia (HHT) presenting with dyspnea and hypoxia. The patient was found to have a giant left-sided PAVM. The patient underwent percutaneous closure of PAVM with multiple devices with a good outcome. At 12-month follow up, the patient was asymptomatic with near complete obliteration of the arteriovenous malformation. <Learning objective: This case demonstrates the feasibility and safety of using multiple devices to treat pulmonary arteriovenous malformation percutaneously. Good short-term (12-month) outcomes are demonstrated and there were no complications.>.
