Late aortic aneurysm is a rare complication of subclavian flap aortoplasty (SCF) for coarctation of the aorta (CoA). Here, we describe the cases of two adult patients with late aortic aneurysm after SCF. The first 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 graft replacement was successfully performed under deep hypothermic circulatory arrest using the retrograde cerebral perfusion technique through a median sternotomy. The 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 graft replacement was successfully performed using the partial bypass technique through a left thoracotomy. The patients were stable without late complications postoperatively after 14 and 13 years, respectively. Long-term follow-up is required for late aortic aneurysms after SCF.
