Anomalous left pulmonary artery (vascular sling) is a congenital anomaly in which the vascular structure arises either from the posterior surface of the right pulmonary artery, or from the main pulmonary artery and courses to the left lung between the posterior surface of the trachea and the anterior surface of the esophagus. It may cause compression on the tracheobronchial tree. It is a rare condition leading to death in the first months of life, if it is not corrected. Its diagnosis is quite difficult because it usually presents non specific symptoms frequently associated to diffuse tracheal stenosis. The authors present a clinical case of a newborn with trisomy 21 who had a left pulmonary artery sling associated to tracheal stenosis and congenital heart disease (complete atrioventricular septal defect). They review the literature, particular in what concerns embryopathogenesis, the difficulties in establishing the diagnosis and the surgery which must be performed as soon as possible.
异常左肺动脉（血管吊带）是一种先天性异常，其中血管结构要么起源于右肺动脉后表面，要么起源于主肺动脉，并在气管后表面和食管前表面之间向左肺走行。它可能会压迫气管支气管树。这是一种罕见的疾病，如果不进行矫正，会在生命的最初几个月导致死亡。其诊断相当困难，因为它通常表现出与弥漫性气管狭窄相关的非特异性症状。作者介绍了一例患有21三体综合征的新生儿临床病例，该患儿伴有左肺动脉吊带、气管狭窄和先天性心脏病（完全性房室间隔缺损）。他们回顾了文献，特别是关于胚胎发病机制、诊断困难以及必须尽快进行的手术方面的文献。
