摘要目的：探索胎儿心室内强回声点在产前诊断中的临床价值。方法：选取2015年9月—2016年11月在本院超声科接受产前超声检查的单胎妊娠孕妇1 442例为研究对象，然后将超声检查出有胎儿心室内强回声点的孕妇分为观察组，选取相同数量的未检出强回声点的孕妇为对照组。观察胎儿心室内强回声点的检出率、数量、心室位置、超声心脏切面位置，比较两组间孕妇的年龄、NT值、孕前体质指数、血红蛋白浓度、现体质指数、腹部皮下脂肪厚度差异。结果：共收集1 587例研究对象，其中145例临床资料不全剔除，最终纳入1 442例。有162例孕妇检出有胎儿心室内强回声，检出率为11.23%，其中131例为左心室单发或多发强回声点，发生率为80.9%；9例为右心室单发或多发强回声点，发生率为5.6%；22例为左、右双心室单发或多发强回声点，发生率为13.6%。162例（100%）孕妇胎儿心室内强回声点均见于心脏四腔心切面。观察组血红蛋白浓度、现体质指数、腹部皮下脂肪厚度均显著低于对照组（P<0.05）。结论：胎儿心室内强回声点是产前超声检查的一种常见的超声影像，常见于左心室，以单发性强回声点为主，回声强度接近或略强于骨骼，多见于心脏四腔心切面，形成的因素可能与孕妇血红蛋白浓度、现体质指数、腹部皮下脂肪厚度等因素有关。

Abstract：Objective: To explore the clinical value of intrauterine strong echo point in prenatal diagnosis. Methods: A total of 1 442 pregnant women with singleton pregnancies who underwent prenatal ultrasonography from September 2015 to November 2016 were selected as subjects, and then the pregnant women with ultrasound examination of the fetal heart with strong echo point were classified as observation group, the same number of pregnant women with undetected strong echo point were selected as the control group. The detection rate, number, ventricular position and ultrasonic heart segment position of fetal heart echoes were observed. The age, NT value, body mass index, hemoglobin concentration, body mass index and abdominal subcutaneous fat thickness were compared between the two groups. Results: A total of 1 587 subjects were collected, of which 145 were excluded for incomplete data and 1 442 were included. There were 162 pregnant women detected fetal intrauterine strong echo, the detection rate was 11.23%. Of which 131 were left ventricular single or multiple strong echo points, the incidence was 80.9%; 9 were the right ventricular single or multiple strong echo point, the incidence was 5.6%; 22 were the left and right ventricle single or multiple strong echo point, the incidence of multiple strong echo points was 13.6%. There are 162 cases of pregnant women with intrauterine ventricular echo points found in the heart of the four-chamber view. The hemoglobin concentration, body mass index and abdominal subcutaneous fat thickness of the observation group were significantly lower than those of the control group(P<0.05). Conclusion: Fetal intraventricular strong echo point is a common ultrasound image of prenatal ultrasound, common in the left ventricle, mainly to a single strong light point, echo intensity close to or slightly stronger than the bones, more common in the heart of the four-chamber view. The formation of factors may be related to maternal hemoglobin concentration, body mass index, abdominal subcutaneous fat thickness and other factors.
