Pulmonary arteriovenous malformations are a rare clinical entity. Most are congenital and asymptomatic but some can cause dyspnea, hypoxemia, hemoptysis, and even more severe complications such as neurological and cardiovascular complications. Endovascular embolization with coils or detachable balloons has shown high therapeutic efficacy but is not exempt from possible complications due to distal migration of these devices. To avoid these adverse events, new devices have been designed with various mechanisms to prevent their migration. We report the case of a large solitary pulmonary arteriovenous malformation successfully treated with an Amplatzer庐 device.
