We present a case of double aortic arch with a predominant right and a double arterial duct detected by echocardiogram in a 28-week gestation foetus. The first evaluation revealed that both arches were perfused; the 1-month postnatal echocardiogram showed the closure of both arterial ducts and the partial obliteration of the left aortic arch between the left subclavian artery and the dorsal aorta. In our case, the postnatal obliteration of the left arch in a double aortic arch was probably due to the closure of the left-sided arterial duct.
我们报告一例妊娠28周胎儿经超声心动图检测发现双主动脉弓，其中右弓为主且存在双动脉导管。首次评估显示两个弓均有血液灌注；出生后1个月的超声心动图显示双动脉导管均已闭合，左主动脉弓在左锁骨下动脉与背主动脉之间部分闭塞。在我们的病例中，双主动脉弓中左弓出生后闭塞可能是由于左侧动脉导管闭合所致。
