Tracheo-bronchial stenosis--report of 3 cases.

Three cases of large airway stenosis of different aetiologies are reported. In the first case, tracheal stenosis occurred after endotracheal intubation. The second case developed bronchial stenosis as a sequelae to pulmonary tuberculosis. The third case had localized stenosis of the left main bronchus for which no cause could be found. The first case responded completely to dilatation while the 2nd case demonstrated only partial response. Third case did not improve significantly with dilatation.
