Vascular ring, in which the trachea and esophagus are completely surrounded by vascular structures, is one of the causes of respiratory distress in children. Right aortic arch with aberrant left subclavian artery is a common aortic arch anomaly; however, respiratory distress due to vascular ring is seldom associated with this anomaly. We report herein a newborn infant treated surgically because of severe respiratory distress caused by vascular ring formed by right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. As laryngomalacia was first thought to be the reason for respiratory distress, we suggest that patients with respiratory distress diagnosed with laryngomalacia be evaluated for possible vascular ring.
血管环是指气管和食管被血管结构完全环绕，是儿童呼吸窘迫的病因之一。右位主动脉弓伴迷走左锁骨下动脉是一种常见的主动脉弓异常；然而，由血管环引起的呼吸窘迫很少与这种异常相关。我们在此报告一名新生儿，因右位主动脉弓伴迷走左锁骨下动脉和左动脉韧带形成的血管环导致严重呼吸窘迫而接受手术治疗。由于最初认为喉软化是呼吸窘迫的原因，我们建议对诊断为喉软化的呼吸窘迫患者评估是否可能存在血管环。
