超声心动图在胸、腹联体儿分离术前的诊断体会

Preoperative Diagnosis of Echocardiography in Thoraco-abdomen Conjoined Twins

目的:探讨胸、腹相连联体儿术前心脏及大血管异常结构或异常联接的超声心动图检查方法及其表现。方法:运用多普勒超声诊断仪对3对胸腹联体儿术前进行超声心动图检查,并对照手术结果进行分析。结果:3对胸、腹联体儿中有1对仅为腹部相连,两患儿均有先天性心脏病,余下2对患儿均为胸、腹部相连接,其中1对中有1人为复杂先心病,另外1对心包融合,心外膜假性粘连,其中有1人为右旋心,另1人伴有先天性心脏病。结果:其中2对患儿均存活;1对中伴有复杂先心病的1人死亡。结论:胸、腹相连联体儿心脏与大血管彩色多普勒切面显示上有一定的困难,但超声心动图检查对联体儿分离术成功有重要意义。

Objective：To investigate the methods and performance of preoperative echocardiography for thoraco-abdomen conjoined twins to determine the abnormal structure of the heart and great vessels or abnormal connection.Method：3 pairs of thoraco-abdomen conjoined twins were examined by echocardiography,and compared with operation detection.Result：1 pair of conjoined twins connected at abdomen ,both had congenital heart disease. The other 2 pairs connected at thoracic and abdominal position,1 baby in one pair had complicated congenital heart disease;another pair got pericardial fusion and epicardial pseudo adhesions,1 had dextral the other had congenital heart disease. Result：2 pairs survived;1 pair of 1 case was death who associated with complex congenital heart disease.Conclusion：There are certain difficulties in color Doppler view plane and window when check the heart and great blood vessels echocardiography for thoraco-abdomen conjoined twins, but echocardiography couplet body children dissection success is very important for the success of dissection operation.
