彩色多普勒超声筛查孕11-13^(+6)w胎儿结构畸形的探讨

The probe of color Doppler ultrasonography of fetal abnormalities at 11 to 13^(+6) weeks

目的探讨彩色多普勒超声筛查孕11-13^(+6)w胎儿结构异常的价值。方法运用彩色多普勒超声2807例11-13^(+6)w胎儿多切面扫查,主要包括:胎儿矢状切面、颈部正中矢状面、颅脑切面、胸部切面、腹部切面、膀胱切面、上肢和下肢切面。结果超声筛查2807例胎儿,其中单胎2505例,双胎151例。发现可疑异常胎儿26例,共检测到结构异常36例:颈部淋巴水囊瘤12例;露脑畸形1例;全前脑4例;Dandy-Walker畸形1例;脉络丛囊肿2例;心脏异常4例;巨膀胱2例;脐膨出2例;肢体异常2例;单脐动脉4例;a波反向2例。结论孕早期超声筛查可检出多系统严重胎儿畸形,避免孕妇更大的精神和肉体的伤害,具有重要价值。

Objective：To explore the value of color Doppler flow image ultrasound in the screening of fetal serious abnormalities in first-trimester fetus. Methods：Two thousand eight hundred and seven fetuses were screened by the color Doppler ultrasonography at 11-13＋6 weeks.Used following sections：fetal sagittal section,sagittal section in the middle of neck,brain,thorax,abdomen,bladder,upper and lower limbs. Results：A total of 2807 fetuses included 151 twins.36 sructural defects were detected in 26 fetuses,including cystic hydroma of the neck（12 cases）,exencephaly（1 case）,alobar holoprosencephaly（4 cases）,Dandy-Walker（1 case）,choroid plexus cysts（2 case）,cardiac defects（4 cases）,megacystis（2 case）,exomphalos（2 cases）,abnormalities of extremities（2 cases）,DVa-wave in reverse（2 cases）,single umbilical artery（2cases）. Conclusions：Many fetal serious structural abnormalities could be detected by ultrasound screening in the first-trimester fetus,which could avoid more hurt of spirit and body for pregnant women.
