目的 总结动脉调转分期手术中左室训练的临床经验。方法 2 0 0 1年4月至2 0 0 4年5月,为7例大动脉转位病儿做左室训练术。左室训练包括体肺动脉分流和肺动脉环缩两项操作。全组肺动脉收缩压 动脉收缩压值,从术前的0 .34增加至0 .76。2例需要同期做原发房间隔切除,1例需要二次校正肺动脉环缩。结果 全组无手术死亡,4例在术后2周左右顺利完成二期动脉调转术,治愈出院。1例术后3个月再入院,做二期动脉调转,术后死于肝功能衰竭。2例因术后并发症未作二期手术。结论 左室训练为年龄超过新生儿期的单纯大动脉转位病儿做动脉调转术提供了必要的准备;房间交通对左室训练有重要作用;快速二期手术可获得良好的临床结果。
Objective To summarize the clinical experience of left ventricular training during arterial transfer staging. Methods From April 2001 to May 2004, seven cases of left atrium were performed left ventricular instrumentation. Left ventricular training includes both pulmonary shunt and pulmonary artery shunt. Systolic pressure of pulmonary artery systolic pressure systolic blood pressure values, from 0.34 to 0.76.2 preoperative need to do the same time, primary atrial septum resection, a case of secondary correction of pulmonary artery systolic. Results There was no operative death in all the cases, and the second phase of arterial transfer surgery was completed in 4 cases at 2 weeks after operation. The patients were cured and discharged. One case was rehospitalized 3 months after operation, and the second phase of artery was transferred. After operation, he died of liver failure. 2 cases of postoperative complications did not make the second surgery. Conclusion Left ventricular training provides the necessary preparation for arterial switch surgery in children with transposition of aorta surpassing the neonatal period. Room traffic plays an important role in left ventricular training. Rapid second-stage operation can achieve good clinical results.
