14～17^(+6)孕周超声筛查胎儿畸形的临床价值

Clinical study of ultrasonography in screening fetal anomaly at 14-17^(+6) week of gestation

目的探讨14~17+6孕周超声筛查胎儿畸形的临床价值。方法回顾性分析2012-2014年在我院进行超声检查的14~17+6孕周胎儿1200例,对其进行标准切面检查,包括测量胎儿双顶径、腹围、股骨长、羊水及胎儿心率,观察头颅、心脏、腹部及脊柱、四肢。结果受检的1200例胎儿中,37例胎儿发现结构异常。其中胎儿水肿6例(包括颈部水囊瘤4例),脉络丛囊肿10例,露脑畸形3例,全前脑3例,脐膨出2例,心脏异常5例,肢体异常2例,脊柱异常2例,巨膀胱3例,连体双胎1例。结论 14~17+6孕周的超声检查可以有效地检出胎儿畸形,是产前超声筛查胎儿畸形的重要阶段。

Objective To evaluate the value of ultrasonography in screening fetal anomaly at 14 to 17＋ 6weeks. Methods A total of 1200 women at 14 to 17＋ 6weeks of gestation were analyzed retrospectively. We measured the biparietal diameter,abdominal circumference,femur length,amniotic fluid and fetal heart rate,and observed the head,heart,abdomen, spine and limbs.Results It was found that 37 fetuses had structural malformations,including 6 cases of hydrops,10 cases of choroid plexus cysts,3cases of exencephaly,3 cases of holoprosencephaly,2 cases of omphalocele,5 cases of congenital heart disease,2 cases of limb deformity,2 cases of spine deformity,3 cases of megabladder,1 case of conjoined twins. Conclusions It is effective to screen fetal anomaly at 14 to 17＋ 6weeks by ultrasonography and it is important for early fetal diagnosis.
