Development of neoaortic pseudoaneurysm after arterial switch operation

Abstract

We report a case of a 46-day-old boy who was diagnosed with transposition of the great arteries and underwent arterial switch operation. A large neoaortic pseudoaneurysm was diagnosed on the first postoperative follow up. Successful repair of the aneurysm was done and at the 3-year follow up, the child's clinical and imaging findings remain normal.

Multiple saccular aortic aneurysms following the arterial switch operation

“…A similar case report of neoaortic pseudoaneurysm in an adult 25 years following ASO has been reported in which the authors postulated that the frailty of the former pulmonary artery tissue was the etiology . Alghamdi et al described another case of aortic pseudoaneurysm near the coronary artery button suture line. This had occurred 3 months after surgery.…”
