Reintervention after ascending–descending aortic bypass for coarctation of the aorta in adulthood

Abstract

Prior to the establishment of a subclavian flap or end–to–end anastomosis, an ascending–descending aortic bypass was conducted to address coarctation of the aorta. Although good results for ascending-descending bypass have been reported in adulthood, reports about its long-term complications after repair in childhood are scarce. We performed reintervention in two adult patients with aneurysmal formation who underwent ascending–descending aortic bypass in childhood. Anatomical repair was performed through median sternotomy with deep hypothermic circulatory arrest. Case 1 is doing well 13 years postoperatively, whereas Case 2 died 4 months postoperatively due to hepatic failure. Close observation is imperative, and early reintervention is necessary when aneurysmal formation is observed.
