超声心动图监测婴儿球囊房间隔造口术体会

Experience of echocardiographic monitoring for balloon atrial septostomy in infants

为了探讨超声心动图在婴儿球囊房间隔造口术中监测的可行性，本文对３例大血管转位合并室间隔完整的婴儿进行球囊房间隔造口术。术中采用超声心动图监测：包括１插入球囊导管通过卵园孔进入左心房，并在左心房内充胀球囊，２回撤球囊导管撕裂房间隔；术后超声显示较大的房间隔缺损及较大量的血流分流。血氧饱和度增加，临床症状改善，２例日后成功行肺动脉环扎术及大血管复位术，１例死于其它并发症。我们认为采用超声监测球囊房间隔造口术，操作简便，图像清晰、重复性好、更优于Ｘ线。

To evaluate the practicability of e chocardiographic(Echo) monitoring for balloon atrial septostomy(BAS) in infants. Echo was used to moniter the Procedures for BAS in 3 infants with transposition of great arteryand intact ventricular septum (TCA/IVS) as a adding image included: ①the balloon catheter inserted across the foramen ovale and inflated in the left atrium. ②the balloon catheter pulled back to appose the atrial septum. After operation, Echo showed a greater atrial septal defect and largerblood shunts. Oxyzen saturations were increased and theclinical symptoms were improved. Two of them were successful Preformed artery banding and arterial switchoperation next time. One was died of the other complications. We believe that BAS is pelformed under Echo monitoring is simple clear, and better than radiography good re peatability.
