[Bronchography in children].

In spite of improvement in the exploratory techniques of the respiratory tract, tracheo-bronchography preserves numerous indications in the study of children's congenital or acquired bronchopneumopathies. The main indications of this investigation consist in the detection of bronchectasies or in the exploratory study of chronic and relapsing bronchial diseases. The investigation makes possible to precise the severity of the disease, to value the results of the medical management and, at last, to select the patients amenable to surgery. Another indications are to be found in the appraisal of some malformative broncho-pneumopathies, with special reference to lung hypoplasias and sequestrations. The technical conditions of the investigation have largely benefited of short duration general anesthesy and of various material improvements (televised fluoroscopy, orientable catheters of small calibre).
