Technique: The defects were located by injecting the cardioplegia solution into left atrium after occluding the pulmonary artery. Through right atrial approach, the large ventricular septal defects were closed by pericardial patch. The smaller ventricular septal defects were closed directly. Results: Out of 33 patients, 20 patients were multiple ventricular septal defects, 5 patients were atrioventricular canal defect with multiple ventricular septal defects and 8 patients were transposition of great arteries with multiple ventricular septal defects. All the patients had severe pulmonary arterial hypertension. The mean age and body weight at repair was 4.51 months and 5.41 kg respectively. Failure to locate additional ventricular septal defects happened in 1 patient where the pulmonary artery banding was done. Six patients had residual ventricular septal defect after surgery, and no significant left to right shunted. One patient had permanent pacemaker implanted in the postoperative period due to the heart block. There was no early and late mortality. Conclusion: Management of multiple ventricular septal defects is quite complex. Right atrial approach of ventricular septal defects closure is safe, simple and effective in closure of multiple ventricular septal defects.展开更多

文摘目的利用经胸超声心动图探讨肺动脉顺应性指数(pulmonary arterial compliance index,PACI)评价行室间隔缺损(ventricular septal defect,VSD)封堵术患者肺动脉顺应性的价值,分析PACI与患者年龄及术后肺动脉收缩压(pulmonary arterial systolic pressure,PASP)变化的相关性。方法选取适合介入封堵治疗的膜周部VSD患者74例,根据年龄分为>40岁组、20～40岁组与<20岁组,根据术后PASP值分为>40 mm Hg组、30～40 mm Hg组与<30mm Hg组,74例患者术前均采用超声心动图测量缺损直径、跨缺损分流压差与PASP,计算VSD面积指数与PACI,术后3个月再次测量PASP,并进行分析及对比。结果 >40岁组术前PACI明显低于20～40岁组与<20岁组,术后PASP高于20～40岁组与<20岁组,差异有统计学意义(P<0.05),3组VSD面积指数比较差异无统计学意义(P>0.05);术后PASP>40 mm Hg组PACI低于30～40 mm Hg组与<30 mm Hg组,VSD面积指数高于30～40mm Hg组与<30mm Hg组,差异有统计学意义(P<0.05)。结论 VSD患者术后PASP的恢复与年龄及PACI相关,PACI可作为评价行VSD封堵术患者PASP恢复程度的指标之一。
