目的探讨提高婴幼儿法洛四联症(TOF)根治术成功率的措施。方法2005年1月至2008年8月共行婴幼儿TOF根治术63例,年龄为2～35个月,体质量3.5～15.0kg。全组经超声心电图检查确诊;肺动脉指数为130～175mm2/m2,左室舒张末期容积指数为28～52ml/m2。全组均在中低温体外循环心脏停跳下行TOF根治术。结果全组术后早期死亡3例,死亡率为4.7%;3例均死于低心排综合征。余60例随访2～44个月,均无严重并发症发生。结论提高手术技巧和加强围术期处理是提高婴幼儿TOF根治术成功率的关键。
Objective To explore the measures to improve the success rate of tetralogy of Fallot (TOF) in infants and young children. Methods From January 2005 to August 2008, 63 children with TOF were treated with TOF, aged from 2 to 35 months and weighing 3.5 to 15.0 kg. The whole group was confirmed by echocardiography; pulmonary artery index was 130 ~ 175mm2 / m2, left ventricular end-diastolic volume index was 28 ~ 52ml / m2. All the patients underwent hypoxic TOF in the hypothermia cardiopulmonary bypass. Results All the patients died of early postoperative death in 3 cases, the mortality rate was 4.7%; 3 patients died of low cardiac output syndrome. More than 60 cases were followed up for 2 to 44 months, no serious complications occurred. Conclusion Improving surgical skills and perioperative management are the keys to improve the success rate of TOF in infants and young children.
