Fetal cardiac great vessel malformation is attracting increasing attention in the prenatal ultrasonic diagnosis of fetal congenital heart disease. To investigate the clinical diagnostic values of three-vessel-trachea view (3VT view) in the ultrasonic diagnosis of this malformation, the present study analyzed the echocardiographic examination results of 77 fetuses with great vessel malformation, retrospectively analyzed the echocardiographic characteristics in the three-vessel-trachea view, and followed up the enrolled cases. The results suggest that great vessel malformation had characteristic manifestations, such as abnormal arrangement order, inner diameter, blood flow direction and branch. Color Doppler flow imaging found V, O, C, U, Ioo and oVo structures. There were 20 cases of blood vessel position abnormality, 38 cases of abnormal blood vessel diameter, and 19 cases of abnormal number of blood vessels. The detection rate of abnormal blood vessel diameter was 95%, which was the highest; the detection rate of abnormal blood vessel position was 97.4%, and that of abnormal number of blood vessels was 84.2%. It is concluded that the 3VT view can indicate fetal cardiac great vessel malformation. The 3VT view is beneficial to timely prenatal diagnosis, relief of body pain and improvement of quality of birth.
胎儿心脏大血管畸形在胎儿先天性心脏病的产前超声诊断中越来越受到关注。为了探讨三血管-气管切面（3VT 切面）在胎儿大血管畸形超声诊断中的临床诊断价值，本研究分析了 77 例大血管畸形胎儿的超声心动图检查结果，回顾性分析了三血管-气管切面的超声心动图特征，并对入组病例进行了随访。结果表明，大血管畸形具有特征性表现，如排列顺序、内径、血流方向和分支异常。彩色多普勒血流成像发现 V、O、C、U、Ioo 和 oVo 结构。血管位置异常 20 例，血管直径异常 38 例，血管数量异常 19 例。异常血管直径的检出率为 95%，最高；血管位置异常的检出率为 97.4%，血管数量异常的检出率为 84.2%。结论：3VT 切面可提示胎儿心脏大血管畸形。3VT 切面有利于及时产前诊断、减轻身体痛苦和提高出生质量。
