Tracheal stenosis by innominate artery compression in infants: surgical treatment in 35 cases.

This is a report on 35 cases of innominate artery compression of the trachea and its surgical correction by means of aortotruncopexy. Diagnostic procedures of choice were tracheoscopy and magnetic resonance imaging, which offers representative images of inspiration and expiration, shows the anatomical relations between aortic arch and trachea and reveals the extent of tracheal compression. Surgical treatment is indicated if narrowing of the tracheal lumen exceeds 70%. By fixation of the aortic arch and the proximal innominate artery to the back of the sternum, tracheal compression is relieved. There was no unsuccessful operation in the 35 children. One late death occurred from cardiac failure, unrelated to tracheal compression.
