Tracheal rings (TR) are rare, congenital cartilaginous defect of the upper airway and are usually due to complete or near complete circumferential cartilaginous tracheal rings, with variable degrees of tracheal stenosis (TS) and shortening. Chromosomal anomalies like trisomy 21 are characteristically associated with a wide range of upper airway anomalies including TS and congenital heart disease (CHD). However, the overall prevalence of severe forms of TS is rare and reported in 1.2% of all CHD patients. Herein, we present a rare association of severe TS due to complete tracheal rings in a trisomy 21 patient with CHD and the challenges in the management.
气管环（TR）是一种罕见的上呼吸道先天性软骨缺损，通常是由于气管软骨环完全或近乎完全呈环状，伴有不同程度的气管狭窄（TS）和气管缩短。像21三体综合征这样的染色体异常通常与包括气管狭窄和先天性心脏病（CHD）在内的多种上呼吸道异常有关。然而，严重形式的气管狭窄总体患病率很低，在所有先天性心脏病患者中报告的比例为1.2%。在此，我们报告了一例患有先天性心脏病的21三体综合征患者因完全性气管环导致严重气管狭窄的罕见病例以及治疗中面临的挑战。
