目的探讨四腔心观(FCV)加三血管-气管观(3VT)在胎儿中晚期心脏病产前超声筛选中的临床意义。方法应用Sequoia512彩色多普勒超声诊断仪,检查孕18~40周胎儿共3211例,与尸体解剖证实和产后超声追踪对照,比较单纯FCV、FCV加左、右室流出道观(FCV+VOTV)、FCV加大动脉短轴观(FCV+SAV)、FCV+3VT筛选胎儿中晚期心脏畸形的敏感性。结果FCV筛选胎儿心脏病的敏感性为54%(91/169),FCV+VOTV的敏感性为70%(118/169),FCV+SAV的敏感性为66%(112/169);FCV+3VT的敏感性为85%(143/169),明显高于前三者(P<0.05)。结论FCV+3VT可以明显提高筛选技术的敏感性,缩短检查时间,可以作为筛选妊娠中晚期胎儿心脏病的首选方法。
Objective To investigate the clinical significance of four-chamber FCV plus three-vessel-tracheal observation (3VT) in prenatal ultrasound screening of middle and advanced fetal heart disease. Methods Sequoia 512 color Doppler ultrasound diagnostic apparatus was used to examine 3211 fetuses aged from 18 to 40 weeks. Compared with autopsy and postnatal ultrasound follow-up, FCV, FCV plus left ventricle and right ventricular outflow tract view (FCV + VOTV) FCV increased arterial short axis view (FCV + SAV), FCV +3 VT screening of fetal heart rate sensitivity in the late. Results The sensitivity of FCV screening for fetal heart disease was 54% (91/169), the sensitivity of FCV + VOTV was 70% (118/169), and the sensitivity of FCV + SAV was 66% (112/169) The sensitivity of 3VT was 85% (143/169), which was significantly higher than the former three (P <0.05). Conclusion FCV + 3VT can significantly improve the sensitivity of screening technology and shorten the examination time, which can be used as the first choice of screening fetal heart disease in the middle and late pregnancy.
