    Abstract:
    Three infants with type A interrupted aortic arch, VSD and PDA underwent staged operation. Aortic arch reconstruction with Blalock-Park's method, PDA division, and PA banding were performed as the first operation. Subsequently all patients were underwent the second operation, consisting of VSD closure and PA debanding, and are doing well now. Pressure gradient at the anastomosis site, the diameters of the anastomosis site and the left subclavian artery, and the diameter ratios of the anastomosis site and the left subclavian artery to the ascending aorta were evaluated after the first and second operation. Two patients with good size of the left subclavian artery at the first operation showed excellent growth of the reconstructed aortic arch and trivial pressure gradient at the anastomosis site. The other patient, whose preoperative left subclavian artery was small (2.5 mm in diameter) resulted in residual stenosis at the anastomosis site. The development of the left subclavian artery was satisfactory in all patients. These data suggest that the aortic arch reconstructed with Blalock-Park's method can grow if the diameter of the anastomosis site has adequate size at the first operation.
