主动脉缩窄35例的外科治疗

外科治疗主动脉缩窄３５例。年龄６～４２岁，平均２２．７岁。单纯主动脉缩窄３１例，合并ＰＤＡ４例。其中切除缩窄主动脉、端端吻合２０例，涤纶片血管成形术８例，应用人工血管移植术７例。手术死亡率５．７％。我们认为主动脉缩窄段切除端端吻合术的优点为消除动脉导管组织，保留锁骨下动脉和避免应用人工材料。且血管成形术简单安全。

Surgical Treatment of Coarctation of the Aorta

Between July 1958 and December 1990,35 patients underwent surgical treatment of coarctation of the aorta.Age at operation varied from 6 to 42 years(mean 22.7 years).Isolated coarctation was present in 31 patients and associated PDA in 4.Rescction and end to end anastomesis was performed in 20 patients and angioplasty with Dacron patch in 8.In another 7 patients,the resected segment was replaced with Dacron or silk vaseular prostheses.Hospital mortality was 5.7%.We recommend resection and end to end anastomosis because this technique not only relieves the obstruction but also eliminates the ductal tissue,preserves the subclavian artery and avoids the use of prosthetic material.But,angioplasty is safe and simple.
