Ascending aortic pseudoaneurysm following Norwood Stage 1 surgery in an infant.

Pseudoaneurysms of the ascending aorta are rarely seen in paediatric patients. They may occur following complex cardiovascular surgery and are associated with a high risk of mortality due to their nature of spontaneous rupture. In this case report, we discuss a 1-year-old paediatric patient with an ascending aortic pseudoaneurysm following Norwood Stage 1 surgery with Sano modification for hypoplastic left heart syndrome and the patient's successful recovery following aneurysmectomy with Norwood Stage 2 operation.
