Tracheal atresia: A Case Report

Abstract

A rare congenital anomaly, tracheal atresia associated with multisystemic malformation is reported. The larynx was developed normally and just below the vocal cord the tracheal lumen was completely occluded. The larynx was connected to the distal trachea by a thin fibrocartilagenous cord that was considered to be a tracheal remnant. The two main bronchi were fused at the canna. No tracheoesophageal fistula was present. The embryonic basis of this anomaly is briefly reviewed. In view of the associated multisystemic malformation, the pathogenesis is presumed to be an insult in a critical embryonic stage,
