B型超声诊断仪检查(下称B超)可以判断胎儿发育,早期诊断胎盘及羊水异常,胎儿畸形和死胎等。随着超声诊断仪分辨率的提高,对胎儿结构畸形的检出时间越来越早,探出的病种亦逐渐增多。不仅对胎儿外形而且对某些胎儿内脏的形态异常,占位性病变也可以作出判断。孕妇早期开始作系统的监护有助于加强孕妇和胎儿围产期保健,对优生优孕有较重要的实用意义。本文报道21例胎儿先天性畸形“B超”下的特点与追踪结果,供同道参考。
B-mode ultrasound examination (hereinafter referred to as B-) can determine fetal development, early diagnosis of placental and amniotic fluid abnormalities, fetal malformations and stillbirths. With the improvement of the resolution of the ultrasonic diagnostic apparatus, the detection time of fetus structural deformity is getting earlier and earlier, and the number of excreted diseases also gradually increases. Not only the shape of the fetus and some fetal visceral abnormalities, occupying lesions can also make judgments. Pregnant women started early systematic care will help strengthen the perinatal care of pregnant women and fetuses, prenatal and prenatal pregnancy have more important practical significance. This article reports 21 cases of fetal congenital malformations under the “B-ultra” characteristics and tracking results for fellow reference.
