Double aortic arch (DAA) is the most common congenital anomaly of the aortic arch system, in which the trachea and esophagus are completely encircled by connected segments of the aortic arch and its branches, often resulting in variable airway compression. We present a case of fetal DAA prenatally diagnosed by fetal echocardiography and clearly confirmed at autopsy. The autopsy visualization allowed for better understanding of this rare cardiac anomaly and facilitated improving the prenatal diagnostic rate.
双主动脉弓（DAA）是主动脉弓系统最常见的先天性异常，其中气管和食管被主动脉弓及其分支的相连节段完全环绕，常导致不同程度的气道受压。我们报告一例通过胎儿超声心动图产前诊断并经尸检明确证实的胎儿双主动脉弓病例。尸检所见有助于更好地理解这种罕见的心脏异常，并有助于提高产前诊断率。
