The persistent high mortality in infants with pulmonary artery "sling" (retrotracheal anomalous left pulmonary artery) is primarily due to the coexistence in such patients of long-segment tracheal stenosis due to complete cartilage rings. Five such patients are reported. Airway studies (by filtered high-kV radiography, bronchography, and/or CT) showed low carina, horizontal equal-length right and left mainstem bronchi, and long-segment tracheal stenosis. The length of the stenosis far exceeded the contact with the pulmonary sling. The suggested term "ring-sling complex" for such patients correctly places emphasis on detection of the tracheal malformation, which currently has no satisfactory surgical treatment.
患有肺动脉“吊带”（气管后左肺动脉异常）的婴儿持续高死亡率主要是由于这类患者存在因完整软骨环导致的长段气管狭窄。本文报告了5例此类患者。气道检查（通过滤线高千伏X线摄影、支气管造影和/或CT）显示隆突低位、左右主支气管水平且等长以及长段气管狭窄。狭窄长度远远超过与肺动脉吊带的接触范围。为此类患者建议的术语“环吊带复合体”正确地强调了气管畸形的检测，而目前对于该畸形尚无令人满意的外科治疗方法。
