目的观察胎儿心脏发育畸形超声和心脏轴测定指标。方法选取2014年4月至2015年4月来汉中市三二〇一医院孕检的孕周为22~28周的70例胎儿资料进行分析,70例胎儿分别行心脏超声联合心脏轴测定和单心脏超声四腔观测定,产后听诊及心脏超声检查分为心脏发育畸形组与正常组,对比两组患儿的心轴角度以及心轴角度异常类型。结果正常组胎儿的心轴角度显著低于心脏发育畸形组[(42.51±5.34)°比(56.25±16.85)°],差异有统计学意义(P<0.05)。正常组仅有1例胎儿出现心轴左偏,心轴左偏率为2.0%,无1例胎儿出现心轴右偏;心脏发育畸形组有8例胎儿出现心轴左偏,心轴左偏率为38.1%;心轴右偏6例,心轴右偏率为28.6%,差异有统计学意义(P<0.01)。结论产前超声检查对于尽早发现胎儿是否存在心脏发育畸形具有一定的应用价值。
Objective To observe fetal heart malformation ultrasound and cardiac axis measurement. Methods From April 2014 to April 2015, 70 fetuses with gestational age ranging from 22 weeks to 28 weeks in gestational age from March 20 to April 20, Hanzhong were enrolled in this study. Totally 70 fetuses underwent echocardiography combined with cardiac axis measurement and single Four-chamber echocardiography, post-natal auscultation and echocardiography were divided into normal and deformity groups. The mandibular angle and the abnormal mandrel angle were compared between the two groups. Results The mandibular angle of the fetus in normal group was significantly lower than that in the group of cardiac dysplasia [(42.51 ± 5.34) ° vs (56.25 ± 16.85 °)], with significant difference (P <0.05). In the normal group, only 1 fetus had a left deviation of the mandible and a left eccentricity of 2.0%, and none of the fetuses had a right deviation of the mandible. In the cardiac development deformity group, 8 fetuses showed left deviation of the mandible and left deviation of the mandible The rate was 38.1%. Right axis deviation in 6 cases, right axis deviation rate was 28.6%, the difference was statistically significant (P <0.01). Conclusions Prenatal ultrasound may be of value in early detection of fetal malformations.
