Interrupted aortic arch (IAA) is a rare complex congenital heart disease characterized by interrupted continuity between ascending aorta and descending aorta. Prenatal diagnosis of IAA by echocardiography is not uncommonly reported despite its rarity. However, employing four-dimensional ultrasound HD-flow imaging and spatiotemporal image correlation (STIC) in diagnosis of this condition has seldom been reported. We report a case of fetal IAA prenatally diagnosed by two-dimensional echocardiography and HD-flow STIC.
主动脉弓中断（IAA）是一种罕见的复杂先天性心脏病，其特征是升主动脉和降主动脉之间连续性中断。尽管 IAA 较为罕见，但通过超声心动图对其进行产前诊断并不少见。然而，利用四维超声 HD-flow 成像和时空关联成像（STIC）诊断这种情况的报道却很少。我们报告了一例通过二维超声心动图和 HD-flow STIC 产前诊断的胎儿 IAA 病例。
