Iatrogenic pseudoaneurysm of patent ductus arteriosus following prior PDA closure in a teenager

Abstract

Iatrogenic pseudoaneurysm after transcatheter closure of patent ductus arteriosus (PDA) is a rare complication and potentially fatal, with a few reported cases in the literature. We reported a 12-year-old child's case of PDA treated with a 12/10-mm Amplatzer duct occluder two years ago, developed with progressive dyspnea, cough, and progressive limitation of physical activity in the last two weeks. The chest computed tomography (CT) scan showed a saccular pseudoaneurysm measuring about 7.4 × 6 × 4 cm in the proximal part of descending aorta. The patient underwent open surgical exploration, the aortic pseudoaneurysm was removed, and an interposition graft was performed. The postoperative outcome was uneventful and without complications. In conclusion, an intragenic pseudoaneurysm following PDA repair is a rare phenomenon. A CT scan provides an excellent evaluation to make a diagnosis and treatment plan. In a resource-limited setting, open surgical repair is still the best option, as performed in our case.
