婴幼儿主动脉缩窄虽然随着手术和术后监护水平的提高而改善了效果,但还不能排除死亡和再缩窄的危险。一些学者指出,球囊扩张术的病死率低于外科手术。现对球囊扩张和手术治疗的资料进行回顾性对比。方法对37例婴幼儿(平均年龄33天,平均体重3.7kg)进行了主动脉缩窄修复手术。13例单纯主动脉缩窄并存其它严重的心脏畸形或血流动力学不稳的病人,采用了锁骨下皮瓣法。24例有主动脉弓严重发育 Infant atrophic stenosis, although improved with increased levels of surgery and postoperative care, does not rule out the risk of death and restenosis. Some scholars point out that the mortality rate of balloon dilatation surgery is lower than surgery. A retrospective comparison of data on balloon dilation and surgical treatment is now available. Methods Thirty-seven infants (mean age 33 days, mean body weight 3.7 kg) underwent aortic stenosis repair. Thirteen patients with isolated aortic constriction and other serious cardiac malformations or haemodynamic instability were treated with the subclavian flap. 24 cases of severe aortic arch development
