三血管序列切面筛选在诊断胎儿心脏病中的临床价值

目的：探讨三血管序列切面筛选在诊断胎儿先天性心脏病中的临床价值。方法：以三血管切面为起始切
面，通过偏转、旋转、移动探头的扫查方式分别依次获取三血管切面、肺动脉分支切面、动脉导管横切面、主动脉
弓切面、三血管-气管切面、肺动脉弓长轴切面、主动脉弓长轴切面和上腔静脉与下腔静脉长轴切面等三血管序列切
面。结果：在231例先天性心脏畸形中，169例在三血管序列切面中至少存在一个切面异常，检出率为73%。如果将不
累及心室流出道的心脏畸形排除在外，三血管序列切面发现心脏大血管畸形的检出率增加至91%。结论：三血管序列
切面提供的大血管解剖信息丰富，可为严重复杂的胎儿心脏畸形的产前筛选、诊断与鉴别诊断提供重要的线索。

3-vessel subsequence view in prenatal screen and diagnosis of fetal congenital heart disease

Objective: To investigate the clinical significance of 3-vessel subsequence view in prenatal
screening and diagnosis of fetal congenital heart disease.
Methods: The 3-vessel subsequence view of 231 fetuses with congenital heart disease was obtained
with Sequoia 512, Voluson 730 and E8 color Doppler ultrasonographic diagnostic system.
Results: Of the 231 consecutive fetuses with congenital heart defects (CHD), 169 (73%) had at
least 1 abnormality on the 3-vessel subsequence view. When ventricl septal defects and so on were
excluded, the detection rate increased to 91%. Some defects had several abnormalities visualized at
the 3-vessel subsequence view.
Conclusion: The 3-vessel subsequence view has high detection rate in identifying the presence of
CHD.
