目的提高对胎儿心脏横纹肌瘤的认识,评价彩色多普勒超声在胎儿心脏横纹肌瘤诊断中的应用价值。方法对近10年来围产儿诊断为胎儿心脏横纹肌瘤8例病例进行随访或引产后进行尸检,回顾性分析该病变的超声特征。结果 8例胎儿彩色多普勒超声均发现心房或心室腔内不同部位单个或多个等回声或强回声光团,直径5.6 mm×5.3 mm～16 mm×28mm,回声均匀,境界清晰,侵犯室间隔及室壁,部分侵及房室瓣口及左室流出道。结论彩色多普勒超声可对胎儿心脏横纹肌瘤准确定位、诊断并随访。
Objective To improve the understanding of fetal rhabdomyosarcoma and evaluate the value of color Doppler ultrasound in the diagnosis of fetal rhabdomyosarcoma. Methods Eight cases of fetal rhabdomyosarcoma diagnosed as perinatal fetuses in the past 10 years were followed up or autopsy were performed. The ultrasound features of the lesions were retrospectively analyzed. Results Eight cases of fetal color Doppler ultrasound were found in different parts of the atrium or ventricular cavity such as single or multiple echo or strong echo light group, diameter 5.6 mm × 5.3 mm ~ 16 mm × 28mm, echo uniform, the state clearly, violations Ventricular septal and ventricular wall, part of the invasion of atrioventricular valve and left ventricular outflow tract. Conclusion Color Doppler ultrasound can accurately locate the fetal cardiac rhabdomyoma, diagnosis and follow-up.
