We present the case of a 29-year-old man who was born with an interrupted aortic arch type A and a ventricular septal defect. At 5 days after birth, he underwent the Blalock–Park aortoplasty through a left thoracotomy. However, when he was one year old, stenosis was noted at the anastomotic site, and the Dacron patch aortoplasty was performed to enlarge the site. Approximately 20 years after the Dacron patch aortoplasty, a thoracic aortic aneurysm was detected at the patch enlargement site which reached a maximum diameter of 45 mm. Although this was the third recurrent left thoracotomy, we successfully performed aneurysmectomy and graft replacement of the thoracic aorta using femorofemoral bypass.
