儿童心脏瓣膜病的机械瓣膜置换手术体会

目的:探讨儿童心脏瓣膜病的人工机械瓣膜置换手术要点及方法.方法:1989年1月至2005年10月,63例15岁以下儿童心脏瓣膜病患者置换机械瓣,全组均采用全麻低温体外循环下进行手术,其中主动脉瓣置换20例,二尖瓣置换37例,主动脉瓣及二尖瓣双瓣膜置换6例.结果:本组手术死亡5例,其他病人均康复出院.出院时心功能Ⅰ～Ⅱ级.随访4月～204月,晚期死亡6例,晚期死亡率为10.34%.结论:儿童瓣膜置换手术死亡率相对较高,但仍是治疗儿童瓣膜病的一种有效办法.

Mechanical valve replacement in children with heart valve diseases

OBJECTIVE: To determine the surgical point and technique of artificial mechanical valve replacement in children with heart valve diseases. METHODS: From Jan. 1989 to Oct. 2005, 63 children under 15 years received mechanical cardiac valve replacement with cardiopulmonary bypass (CPB). RESULTS: The valve replacement included aortic valve replacement in 20 children, mitral valve replacement in 37 children and combined aortic valve and mitral valve replacement in 6 children. CONCLUSION: The operation mortality was 7.94%(5/63). The follow-up periods were from 4 months to 204 months. The late mortality was 10.34%(6/58). All the other children were in NYHA class I - II. The operation mortality of children with heart valve replacement is higher than that of adults, but it was very effective.
