[Clinical aspects and diagnosis of tracheal compression stenosis in childhood]

Four stages of compression of the trachea were identified on the basis of the treatment of 18 patients. The regularity of the appearance of secondary and immediate signs was established. A phasic pattern of the development of stenosis was found to be characteristic of the acquired pathology, while congenital stenosis was characterized by a gradual growth of secondary changes in the broncho-pulmonary system. The principles of diagnosing the disease are described.
