产前超声诊断胎儿主动脉缩窄的研究进展

Progress in prenatal sonographic diagnosis of coarctation of aorta

超声心动图是诊断胎儿主动脉缩窄的首选影像学检查方法。目前已有一些典型的超声征象用于产前诊断胎儿主动脉缩窄, 但尚无单一征象可以准确诊断或排除主动脉缩窄, 而超声评分系统在诊断主动脉缩窄及风险分级等方面仍处于探索中。本文就产前超声诊断胎儿主动脉缩窄的研究进展作一综述。

Fetal echocardiography is the first-line imaging tool for diagnosing coarctation of aorta(CoA).Currently,there are some typical ultrasonic features,but no single one can be used for accurate prenatal diagnosis or differential diagnosis of fetal CoA and ultrasonic scoring system remains under investigation in diagnosing or risk classification of CoA.This paper reviews the progress in prenatal ultrasound diagnosis of fetal CoA.
