目的 探讨产前彩色多普勒超声诊断胎儿梅干腹综合征(PBS)的价值。方法 分析我院产前彩色多普勒超声检出的11胎疑似PBS胎儿的声像图特征,并与产后外观或病理结果对比,验证超声检查的准确性。结果 11胎均见腹腔内巨大囊性占位,周边可探及脐血流信号(提示为巨膀胱);6胎泌尿系畸形;3胎腹壁菲薄;6胎羊水过少;4胎合并其他异常;2 胎胎死宫内。9胎引产(7胎为PBS,1胎为后尿道瓣膜症,1胎为尿道闭锁);2胎出生(1胎为PBS,1胎为单纯腹腔囊肿)。产前彩色多普勒超声对PBS的检出率为0.17‰(8/47 624),准确率为72.73%(8/11)。结论 腹横径/膀胱直径、腹壁厚度作为诊断标准可提高产前诊断PBS准确率,产前彩色多普勒超声早期诊断胎儿PBS具有较高的临床诊断价值。
Objective To explore the value of prenatal color Doppler ultrasonography in the diagnosis of prune-belly syndrome(PBS).Methods The characteristics of ultrasonogram of 11 fetuses suspected PBS were analyzed and compared with postnatal appearance or pathological findings.Results Eleven fetuses had large intraperitoneal cyst,umbilical blood flow signal surrounding(hint for the megacystis) were explored.Six fetuses had urinary malformations,while 3 had abdominal wall meager.Oligohydramnios was noticed in 6 fetu...
