体外循环心脏不停跳下心外管道Fontan手术

目的评估体外循环心脏不停跳下心外管道Fontan手术的方法及其效果。方法本组42例中,男性31例、女性11例,年龄3～19岁,其中心室双人口19例,三尖瓣闭锁10例,二尖瓣闭锁3例,其他复杂先天性心脏病10例。均在常温体外循环心脏不停跳下施行心外管道Fontan手术,其中8例加行开窗术;1例先做了双向腔肺动脉分流术,术后2年行心外管道Fontan手术。结果术后早期和晚期各死亡1例,分别死于急性肝功能衰竭和反复肺部感染,随访1．0～4．5年,40例心功能为Ⅰ级和Ⅱ级,动脉血氧饱合度92％～96％。结论体外循环心脏不停跳下心外管道Fontan手术的近、中期效果满意．可在单一心室修复中选用。

Fontan operation with extracardiac conduit on beating hearts

OBJECTIVE: To evaluate the results of Fontan operation with extracardiac conduit on beating hearts. METHODS: Forty-two patients (31 males and 11 females) age ranged from 3 to 19 years old included in this study. There were 19 double inlet-ventricle, 10 tricuspid atresia, and 3 patients with mitral atresia, 10 patients with other complex congenital cardiac malformations. Fontan operations with extracardiac conduit were performed in all patients with the help of cardiopulmonary bypass without hypothermia in this study. Atrial septal fenestration was performed in 8 patients. In one patient, bi-directional cardiopulmonary procedure was performed 2 years before Fontan operation. RESULTS: There was one early death caused by acute hepatic function failure and one late death caused by repeated lung infections. The follow-up of 1 to 4.5 years showed that all patients' cardiac functions were grade I to II, and arterial oxygen saturation was 92% - 96%. CONCLUSIONS: The early and mid-term outcome of Fontan operation with extracardiac conduit on beating hearts is good and the method can be used in the single ventricle repair.
