目的 评价同种带瓣肺动脉片在小儿重症法洛四联症 (TOF)根治术中应用的效果。方法 17例小儿重症TOF术中应用同种带瓣肺动脉片行右室流出道跨环补片。随诊 4个月～ 6年 ,平均 1.8年。结果 全组手术成功率 94 .1% ,无晚期死亡 ,无带瓣血管片钙化与反流等情况发生。结论 在小儿重症TOF根治术中 ,同种带瓣肺动脉片是右室流出道跨环补片的理想材料。
Objective To evaluate the effect of allogeneic pulmonary valve strips in pediatric severe tetralogy of Fallot (TOF). Methods 17 cases of pediatric severe TOF surgery using the same flap with pulmonary valve right ventricular outflow tract cross-ring patch. Followed up for 4 months to 6 years, an average of 1.8 years. Results The success rate of the whole operation was 94.1%, no late death, no valve flap calcification and reflux occurred. Conclusion In pediatric severe TOF radical resection, allograft pulmonary valve is the ideal material for trans-annular patch of right ventricular outflow tract.
