Abstract
Two patients with type A Interrupted Aortic Arch (3 days old and 12 months old) underwent staged operation. Aortic arch reconstruction with Blalock-Park's method, PDA division, and PA-banding were performed as the first operation. Subsequently one of them underwent the second operation (VSD closure and debanding) and is now doing well. The other baby is growing well and the second operation is not yet performed because of aortic valve deformity and possible need of valve replacement. Postoperative pressure gradient across the Blalock-Park's anastomosis was slight and perfusion to lower half of the body was favorable. There also recongnized the growth of the reconstructed aortic arch on the postoperative aortography. As the preoperative condition of patients with interrupted aortic arch is usually severe, staged operation is recommended. Aortic arch reconstruction with Blalock-Park's method, PDA division, and PA-banding were thought to be a preferable method as the first operation.
