目的:探讨经阴道彩色多普勒超声(TVCDS)诊断14~16孕周胎儿心脏结构异常的方法和价值。方法:对76例14~16孕周、有高危妊娠病史或经腹检查不满意的孕妇进行经腹部和阴道彩色多普勒超声对比检查,并与胎儿引产结果及产后超声心动图进行对照。结果:76例中发现胎儿心脏异常4例,经腹部与阴道彩色多普勒超声心动图检查总结果对比差异无统计学意义(P>0.05),而肥胖孕妇检查结果对比差异有统计学意义(P<0.01)。结论:经腹部超声检查联合经阴道彩色多普勒超声心动图检查是诊断早期胎儿心脏病的首选方法。
Objective: To investigate the method and value of transvaginal color Doppler ultrasound (TVCDS) in diagnosing fetal cardiac structural abnormalities from 14 to 16 gestational weeks. Methods: 76 cases of 14 to 16 gestational weeks, pregnant women with high risk pregnancy or abdominal examination were not satisfied with the pregnant women by abdominal and vaginal color Doppler ultrasound contrast test, and fetus induction of labor and postpartum echocardiography were compared. Results: Abnormal fetal heart was found in 4 of 76 cases. There was no significant difference in the results of abdominal and vaginal color Doppler echocardiography (P> 0.05), but there was significant difference in obese pregnant women P <0.01). Conclusion: Transabdominal ultrasound combined with transvaginal color Doppler echocardiography is the preferred method of diagnosis of early fetal heart disease.
