产前超声诊断中胎儿心室内强回声点的临床意义

Clinical Significance of Strong Echogenic Points in Fetal Ventricles in Prenatal Ultrasound Diagnosis

目的:分析胎儿心室内强回声在产前诊断中的价值。方法:选择2020年1月~2023年1月于本院实施产前超声检查的单胎妊娠孕妇及其胎儿为观察对象,共686例,检出胎儿心室内强回声86例,将检出者列为观察组,未检出者列为对照组,统计胎儿心室内强回声检出率,分布情况,切面位置,对照胎儿及孕妇的检查资料,对照不同分布下强回声对于先天性心脏病的诊断参考价值。结果:存在胎儿心室内强回声光点的观察组产妇年龄、孕次、孕周、孕前体重、空腹血糖、餐后2h血糖、妊娠期糖尿病、妊娠期高血压、孕期暴露、TORCH感染以及胎儿NT值与未见胎儿心室内强回声光点对照组无明显差异(P>0.05),而观察组的当下体重、体质量指数、血红蛋白浓度、以及产妇的妊娠期贫血、超重、孕期暴露、TORCH感染发生率,胎儿心脏结构异常发生率均高于对照组(P<0.05)。结论:胎儿心室强回声点属于产前超声检查的常见超声表现,主要为单发强回声点,多见于心脏四腔心切面,可在胎儿心脏疾病的筛查中提供参考。

Objective:To analyze the value of fetal intraventricular strong echo in prenatal diagnosis.Methods:Study sample collected during January 2020 to January 2023 in our prenatal ultrasound examination of pregnant women and their fetus as the observation object,a total of 686 cases,86 cases of fetal ventricular strong echo,the detection as the observation group,the statistics of fetal ventricular strong echo detection rate,distribution,section position,control the examination data of fetus and pregnant women,control the different distribution under strong echo reference value for the diagnosis of congenital heart disease.Results:In the observation group with strong echo light point,maternal age,pregnancy time,gestational week,pre-pregnancy weight,fasting blood glucose,2h postprandial blood glucose,gestational diabetes,gestational hypertension,exposure during pregnancy,TORCH infection,and fetal NT value and no strong echo light point in the fetal ventricular chamber(P>0.05).In the observation group,the current body weight,body mass index,hemoglobin concentration,and maternal anemia during pregnancy,overweight,exposure during pregnancy,and the incidence of TORCH infection,the incidence of structural cardiac abnormalities was higher than that in the control group(P<0.05).Conclusion:The strong echo point of fetal ventricle belongs to the common ultrasound manifestation of prenatal ultrasound examination,mainly for the single strong echo point,which is mostly seen in the heart of the four chambers,and can provide reference in the screening of fetal heart disease.
