Abstract
Aortic pseudoaneurysm is a rare but life-threatening complication after transcatheter closure of patent ductus arteriosus (PDA) with only a few reported cases in literature. We report a case of an 18-month-old child who was diagnosed to have pseudoaneurysm of the aorta after 6 months of transcatheter closure of PDA. It was diagnosed on routine follow-up on echocardiography evaluation. Computed tomography chest is the imaging modality of choice for evaluation of these patients which showed large saccular aneurysm arising from distal aortic arch beyond origin of left subclavian artery. Any aneurysm more than 30 mm should be treated irrespective of symptoms. Treatment modalities are surgical resection of the aneurysm (as in our patient) or thoracic endovascular aortic repair. In our case, surgical resection of aneurysm was performed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12055-023-01619-z.
