Pulmonary artery aneurysm (PAA) and pulmonary artery pseudoaneurysm (PAP) are rare diagnoses in the pediatric population and carry a high risk of mortality if rupture occurs. There is currently no standard therapeutic approach to PAAs and PAPs. Reports of surgical intervention describe high mortality. We present a case of an infant with a PAP that was successfully treated with a percutaneous device closure. Our approach included deployment of a 6-mm Amplatzer Vascular Plug 2 (Abbott, St. Paul, MN) in the right lower pulmonary artery segmental branch just proximal to the origin of the pseudoaneurysm. Subsequent imaging 1-month post-procedure demonstrated a >50% reduction in the size of the PAP when compared to original imaging studies and near-complete resolution 14 months following the intervention. Percutaneous device placement to occlude the vessel supplying peripheral PAAs and PAPs may be a reasonable alternative to open surgical resection when treating patients with this rare, but potentially life-threatening vascular anomaly. To our knowledge, this is the first case describing a successful device closure of a PAP in an infant weighing <3 kg.
