中文摘要：

目的分析探讨经右心房和肺动脉矫治婴幼儿法洛四联症的临床效果。方法选择2009年12月～2011年12月收治的婴幼儿法洛四联症患儿120例，分为实验组及对照组。实验组60例患儿采用经有心房和肺动脉路径矫治．对照组60例患儿采用经右心房路径矫治，随访至术后12个月，比较两组患儿术后并发症的总发生情况及死亡率。结果实验组急性肾功能不全、房室传导阻滞以及胸腔积液等并发症的总发生率（3．33％）明显低于对照组（30．00％），差异有统计学意义（X^2=15．360，P〈0．05）；随访至术后12个月，实验组患者死亡率（0）明显低于对照组（25．00％），差异有统计学意义（X^2=21．143，P〈0．05）。结论经右心房和肺动脉径路矫治婴幼儿法洛四联症可有效提高外科治疗婴幼儿法洛四联症的手术效果。

英文摘要：

Objective To analyze and discuss clinical effect of treating infant tetralogy of fallot through atrium dextrum and pulmonary artery. Methods 120 cases of these tetralogy of fallot infant patients from December 2009 to December 2011 were chosen and divided into experimental group and control group. 60 patients in experimental group were treated through atrium dextrum and pulmonary artery, 60 cases in control group were treated through atrium dextrum. All the patients were followed up for 12 months after surgery, the total occurrence of complications and death rate were compared. Results The total incidence of acute renal insufficiency, atrioventricular block and pleural effusion in experimental group （3.33%） was lower than that in control group （30.00%）, the difference was statistically significant （X^2= 15.360,P 〈 0.05）; the death rate in experimental group （0） was lower than that in control group （25.00%）, the difference was statistically significant （X^2 = 21.143,P 〈 0.05） 12 months after surgery. Conclusion Treating infant tetralogy of fallot through atrium dextrum and pulmonary artery can improve operation results significantly.
