Left pulmonary artery stenosis is a well-recognized complication following the Norwood procedure. We herein report two cases in which ascending aortic extension was performed to enlarge the retroaortic space in children with left pulmonary artery stenosis after the Norwood procedure. We used graft interposition in the ascending aorta to increase the retroaortic apace and concomitantly performed extended left pulmonary artery reconstruction. This procedure obtains a more balanced distribution of the pulmonary blood flow, which is crucial to achieve good Fontan circulation.
升主动脉延伸术在 Norwood 手术后左肺动脉狭窄患儿中的应用
左肺动脉狭窄是 Norwood 手术后一种公认的并发症。本文报告了 2 例升主动脉延伸术用于扩大 Norwood 手术后左肺动脉狭窄患儿的主动脉后间隙的病例。我们采用移植物置入升主动脉以增加主动脉后间隙，并同时进行左肺动脉重建。该手术可获得更均衡的肺血流分布，这对于实现良好的 Fontan 循环至关重要。
