大动脉转换术治疗新生儿完全性大动脉错位

目的 回顾总结完全性大动脉错位（D－TGA）的手术治疗。方法 1999年11月至2001年8月，采用大动脉转换术（Switch）手术方法纠治新生儿D－TGA 16例，其中室间隔完整型大动脉错位（D－GA／IVS）6例，大动脉错位伴室间隔缺损（D－TGA／VSD）10例。所有病例都在深低温低流量和深低温停循环下行Switch纠治术。结果 Switch手术治疗TGA共16例，其中TGA／IVS 6例，无死亡；TGA／VSD 10例，死亡2例，均为伴有冠状动脉畸形者。14例随访2－20个月，VSD残余漏1例，肺动脉轻度残余梗阻2例，14例心功能均良好。结论 Switch手术是D－TGA纠治的首选方法，但必须早期手术。

Arterial Switch operation for complete transposition of great arteries in neonates

Objective: To review and summarize the experience of surgical repair of transposition of great arteries (D TGA). Methods: Sixteen patients with TGA were treated by arterial Switch operation during November 1999 to August 2001. There were 6 patients with transposition of great arteries and intact ventricular septum (D TGA/IVS), and 10 patients with transposition of great arteries and ventricular septum defect (D TGA/VSD). The operation was carried out under deephypothermia circulatory arrest and low flow perfusion. Results: There were 2 deaths with mortality rate of 12.5%. The two deaths occurred in all patients with D TGA/VSD with abnormal coronary arteries. 14 patients were follow up from 2 months to 20 months. There were one residual VSD and two mild pulmonary obstructions. All patients had good heart function. Conclusion: The Switch operation can be considered ass the first choice for surgical repair of D TGA in neonates, and should be performed as early as possible.
