Late Aortic Aneurysm Following Subclavian Flap Aortoplasty for Coarctation of the Aorta: A Report of Two Adult Cases

Abstract

Late aortic aneurysm is a rare complication of subclavian ap aortoplasty (SCF) for coarctation of the aorta (CoA). Here, we describe the cases of two adult patients with late aortic aneurysm a er SCF. e rst patient was a 26-year-old man who underwent SCF for a simple CoA at 3 years old. He had a fusiform type of aortic aneurysm located at the site of SCF. Aortic gra replacement was successfully performed under deep hypothermic circulatory arrest using the retrograde cerebral perfusion technique through a median sternotomy. e second patient was a 34-year-old woman who underwent SCF for a simple CoA using SCF at 6 years old. She had a saccular type of aortic aneurysm in the distal lesser curvature wall of the SCF. Aortic gra replacement was successfully performed using the partial bypass technique through a le thoracotomy. e patients were stable without late complications postoperatively a er 14 and 13 years, respectively. Long-term follow-up is required for late aortic aneurysms a er SCF.
