[Case report of tracheal stenosis].

This is the report on one case of tracheo-stenosis after aspiration of a foreign body which has been diagnosed only after 7 years and successfully treated by surgery. Based on this case, the symptoms of stenosis of trachea or main bronchus are described and it is referred to the difficulties of diagnosis. Anamnesis, therapy-resistant cough and dyspnea, inspiratoric stridor, isolated stenotic murmur in central bronchial sections or a weakened respiratory sound give a hint to the existence of a stenotic process which is to be confirmed by tomography and bronchoscopy. Problems of misinterpretation of such symptoms are discussed.
