微机分析法洛四联症根治术后死亡危险因素

Computerized Analyses of the Risk Factors of Death Following Total Correction of Tetralogy of Fallot

本文对３３７例法洛四联症根治术后早期死亡危险因素进行微机分析，结果发现手术死亡与手术年限、患者年龄、长时间体外循环和升主动脉阻断时间有关；其它术后死亡危险因素还有患者肺动脉及其分支发育情况、主动脉骑跨程度、术中是否跨肺动脉瓣环补片、术后ＰＲＶ／ＬＶ比值及术后出血和输血量。

Three hundred and thirty seven patients undergoing total correction of tetralogy of Fallot were analysed with computer to determine the risk factors related to the early death after the surgical procedures.The results revealed that operation in early years,young age(≤6 years old),long cardiopulmonary bypass time and the ascending aorta arrest time were significant determinants of operative mortality.Other important determinants were the conditions of pulmonary artery and its branches,the percentage of aortic overriding,transannular right ventricular outflow patch(TAP),P RV/LV and the bleeding and transfusion at the first day following the operation.
