应用一期大动脉调转术治疗完全性大血管错位

目的探讨一期大动脉调转术(Switch术)在完全性大血管错位(D—TGA)中的应用。方法 2004年4月至2009年3月应用一期Switch术治疗完全性大血管错位10例。其中室间隔完整型大血管错位(D-TGA/IVS)5例,大血管错位伴室间隔缺损(D-TGA/VSD)5例;手术平均年龄(39±21.8)d,体重(3.65±1.24)kg。结果手术死亡2例,其余随访3个月-4年,心脏彩超提示心脏功能状况良好,肺动脉轻度残余梗阻1例。结论一期Switch术在完全性大血管错位中的应用可以取得良好的手术效果,及早手术和冠状动脉移植的通畅,是手术成功的关键。

Primary arterial switch operation used in congenital heart disease with complete transposition of great arteries

Objective To review and summarize primary arterial switch operation used in complete transposition of great arteries （D-TGA）. Methods Ten patients with complete transposition of great arteries were repaired by primary arterial switch operation during April 2004 to March 2009. There were 5 patients with transposition of great arteries and intact ventricular septum （D- TGA/IVS）, and 5 patients with transposition of great arteries and ventricular septal defect （D-TGMVSD）. The operative age was （39±21.8）days, and weight （3.65±1.24）kg. Results There were 2 deaths. 8 patients were followed-up 3 months to g years.There was one mild pulmonary obstruction. The echocardiography of all patients showed good heart function. Conclusion The primary arterial switch operation used in complete transposition of great arteries had a satisfactory results. The successful operation is the key that switch operation should be performed as early as possible and implantation of the coronary had to he patent.
