孤立的左侧无名动脉，一种罕见的先天性异常，其中左侧无名动脉来自主肺动脉干，通常在儿童和成人中被诊断为偶然。关于其产前诊断的报告有限，没有全面描述相关的围产期血流动力学变化。我们报告一例产前诊断为孤立的左侧无名动脉，描述产后临床过程。
Isolated left-sided innominate artery, a rare congenital anomaly in which the left-sided innominate artery arises from the main pulmonary trunk, is usually diagnosed incidentally in children and adults. Limited reports exist on its prenatal diagnosis, with none comprehensively describing the associated perinatal haemodynamic changes. We report a case of prenatally diagnosed isolated left-sided innominate artery, describing the postnatal clinical course.
