目的 :总结婴幼儿法乐四联症 (TOF)根治手术的经验。方法 :分析我科 1994年 1月至 1996年 12月共 2 1例低体重 (<10 kg)婴幼儿 TOF,年龄 14.7± 6 .95(5～ 2 4 )个月 ,体重 8.2 4± 1.6 7(5～ 10 )kg。手术均在深低温低流量体外循环下进行。经右心室或右房 -右室切口修补室间隔缺损 ,切除漏斗部肥厚的肌束 ,自体心包片加宽右室流出道或跨环补片。结果 :手术死亡 1例 (手术死亡率 4 .76 % )。术后主要并发症有低心排综合征、肺部感染、气胸、一过性室上性心律失常等。 2 0例痊愈出院。结论 :合理的手术操作并彻底纠治畸形、良好的体外循环灌注以及正确的术后处理是手术成功的关键 ,对婴幼儿施行TOF根治术是切实可行的
Objective: To summarize the experience of radical surgery of tetralogy of Fallot (TOF) in infants and young children. Methods: A total of 21 infants with low birth weight (<10 kg) from January 1994 to December 1996 were analyzed. The TOF was 14.7 ± 6.95 (5 ~ 24) months and the body weight was 8.2 4 ± 1.6 7 (5 ~ 10) kg. Surgery were carried out in deep hypothermia and low flow cardiopulmonary bypass. Through the right ventricle or right atrium - right ventricular incision repair ventricular septal defect, excision of hypertrophy of the funnel Department of muscle bundles, pericardial thoracic widening right ventricular outflow tract or cross-ring patch. Results: 1 case died of surgery (operative mortality 4.76%). The main postoperative complications are low cardiac output syndrome, pulmonary infection, pneumothorax, transient supraventricular arrhythmias. 20 cases were discharged. Conclusion: Reasonable surgical operation and complete correction of deformity, good perfusion and correct postoperative treatment is the key to the success of surgery, the implementation of TOF in infants and young children is feasible
