Background:
The aortic arch repair for interrupted aortic arch (IAA) with the hypoplastic ascending aorta through a median sternotomy requires cardiopulmonary bypass (CPB), which is very invasive in neonates and complicates pulmonary artery banding (PAB) is staged repair.
Methods:
A 22-day-old neonate with a type B IAA having a functional single ventricle underwent arch repair and PAB through a median sternotomy without CPB. A partial occlusion clamp could be placed on the ascending aorta without cerebral malperfusion and the descending aorta could be directly anastomosed to the ascending aorta in an end-to-side fashion under stable circulatory condition. Thereafter, the tight PAB was performed with a circumference of 23mm without any difficulty.
Results:
The postoperative echocardiogram revealed no stenosis on the anastomotic site and the patient was discharged uneventfully.
Conclusion:
This approach is effective in neonates with IAA who require staged repair, and least invasive for them.
