摘要
目的探讨一种新的主、肺动脉根部置换手术治疗合并室间隔缺损(VSD)、左室流出道梗阻(LVOTO)的大动脉错位(TGA)。方法4例伴LVOTO、VSD的TGA患者及1例伴LVOTO、VSD的右心室双流出口患者,被采用改良的Nikaidoh技术将主动脉和肺动脉根部完整互换移植、冠状动脉移植以及双心室流出道重建;其中2例房室异常连接患者被同期施行Senning手术。结果所有患者手术均获成功,术后恢复良好。术后平均随访5.40个月,生长发育好。超声心动图检查提示心室功能良好,主动脉瓣无反流;2例患者肺动脉瓣有少量反流。结论保留半月瓣的主、肺动脉根部置换术治疗伴LVOTO的复杂型TGA患者,不仅可获得解剖根治,同时解决了右心室流出道的非生长性问题,改进的冠状动脉再植技术扩大了Nikaidoh手术的适应范围,并获得很好的近期疗效。但其远期疗效仍需更大组的手术例数及更长期的随访来验证。
Objective To investigate the clinical application of a novel modified aortic and pulmonic translocation in surgical repair of transposition of great arteries (TGA) with ventricular septal defect (VSD) and left ventricular outflow tract obstruction(LVOTO). Methods Five patients received surgical repair of the TGA with VSD and LVOTO at our heart center. The surgical technique used was a modification of the Nikaidoh procedure by which the native pulmonary root was preserved and translocated to reconstruct the right ventricular outflow tract. Two patients with atrioventricular discordance required a Senning procedure. Results All patients survived the operation and were discharged from the hospital. There were no major complications. At a median follow-up of 5.40 months, the echocardiography demonstrated normal ventricular function in all patients. No residual aortic stenosis or insufficiency was found in all the patients. Two patients had mild pulmonary insufficiency. Conclusions The novel modification of the Nikaidoh procedure may have excellent early results with minimal postoperative pulmonary insufficiency. The procedure may also allow growth of the pulmonary root and therefore decrease the need for reoperation. However, this has to be further investigated and long-term follow-up studies are warranted.
