Transcatheter embolotherapy of giant pulmonary arteriovenous malformation using Amplatzer® vascular plug

Pulmonary arteriovenous malformation (PAVM) is a rare pulmonary vascular anomaly due to an abnormal communication between the pulmonary artery and vein. The most common presenting symptom is a dyspnea on exertion related to this right-to-left shunt. If left untreated, PAVM has been known to result in serious complications. Incomplete pulmonary capillary network can be the cause of cerebral abscesses and other non-infectious neurological complications, such as stroke and transient ischemic attacks due to paradoxic embolism Transcatheter embolotherapy, using coils or balloons, has replaced surgical resection as the treatment of choice for PAVM. However, the risk of device embolization has limited the use of coil embolotherapy, while the size of PAVM is huge. Recently, Amplatzer Vascular Plug has been proposed as an alternative endovascular occlusion device for arteriovenous malformation. We report a case of 81-year-old male patient with a giant PAVM, which was successfully treated by transcatheter embolotherapy using the Amplatzer Vascular Plug. Copyright
