CONGENITAL TRACHEAL ANOMALIES - PATHOLOGY STUDY USING SERIAL MACROSECTIONS AND REVIEW OF THE LITERATURE

This description of congenital tracheal lesions is presented with a fo cus on the information derived from the specimens collected for the La ryngeal Development Laboratory at the Children's Memorial Hospital in Chicago from 1975 to 1992. During this period, 115 laryngotracheal spe cimens were obtained, 22 of which were found to have congenital trache al anomalies. Six specimens were determined to have tracheomalacia, in cluding one with primary tracheomalacia and five with secondary trache omalacia: three were associated with tracheoesophageal fistula and two with aberrant innominate artery. Thirteen specimens had a trapped fir st tracheal arch; one, complete tracheal rings; and two, tracheal cart ilaginous sleeve. Three specimens had tracheal agenesis, and three, tr acheoesophageal fistula. Some specimens have more than one tracheal an omaly. Sixteen patients also had anomalies of other systems.
