Congenital double aortic arch (DAA) is an uncommon vascular anomaly; however, its prenatal detection is associated with congenital heart defects and chromosomal abnormalities, including 22q11 deletion. We present a case of DAA diagnosed prenatally. DAA can be diagnosed by prenatal ultrasound in the transverse three vessel-trachea view, which shows a trident image formed by a complete vascular ring and the ductus arteriosus. Postnatal magnetic resonance images in this view correlate well with prenatal ultrasound images and help in confirmation of diagnosis, evaluation of the risk of airway or esophageal compression, and planning of surgery.
先天性双主动脉弓（DAA）是一种罕见的血管异常；然而，其产前检测与先天性心脏缺陷和染色体异常有关，包括22q11缺失。我们报告一例产前诊断为DAA的病例。DAA可通过产前超声在横断位三血管-气管视图中诊断，该视图显示由完整血管环和动脉导管形成的三叉戟图像。此视图下的产后磁共振图像与产前超声图像相关性良好，有助于确诊、评估气道或食管受压风险以及手术规划。
