A neoaortic aneurysm after a Norwood type reconstruction of the aorta can develop due to systemic pressure on the former pulmonary artery wall. A complex valve sparing procedure can preserve native valves and avoid a valve replacement with requirement for anticoagulation. This type of operation was carried out in 3 patients, 2 of them after a Fontan palliation, 1 after a Norwood-Rastelli repair. The reconstruction was done using Dacron prostheses for the replacement of the dilated wall, similar to a Yacoub modification in 2 cases and to a David's modification in 1 patient. The postoperative course was uneventful and postoperative valve function was good in all cases.
升主动脉重建后的新发主动脉瘤可能由于前肺动脉壁承受系统性压力而发生。复杂的保留瓣膜手术可以保留原生瓣膜，并避免因需要抗凝而进行瓣膜置换。该手术类型已在 3 名患者中实施，其中 2 名在法洛四联症姑息术后，1 名在 Norwood-Rastelli 修复术后。使用膨体聚四氟乙烯（Dacron）假体进行扩张壁的替换，类似于 2 例的 Yacoub 改良和 1 例的 David 改良。术后过程平稳，所有病例的术后瓣膜功能均良好。
