208 time, in 84 (87.5%) patients, cough was accompanied by discharge of mucopurulent or purulent sputum. 12 (12.5%) patients were bothered by a dry, "barking", painful cough. The second most frequent symptom was shortness of breath with light physical exertion, which bothered 55 (57.3%) patients. High temperature was noted in 19 (19.8%) patients, subfebrile — in 20 (20.9%) patients. X-ray examination (chest scan in direct and lateral projections) performed in all 96 patients admitted with a diagnosis of LC revealed deformation and enhancement of the pulmonary pattern in 55 (57.3%) patients; signs of emphysema combined with moderate peribronchial fibrosis in 26 (27.1%) patients. Reticular pneumosclerosis occurred in 24 (25%) patients, peribronchial infiltration with a characteristic uniform thickening of the bronchial walls without clear external contours, as well as severe opacification associated with the flattened root of the lung in 17 (17.8%) patients. Signs of volumetric reduction of the segment or lobe were noted in 4 (4.2%) patients, and central lung cancer was suspected in 6 (6.3%) patients. All the above-described changes in lung tissue indicated possible diseases that could cause LC (with focal lesions, volumetric and cavity formations). According to the radiographs of all 96 patients, conclusions were made about the side of the lesion, the presence of hydrothorax - in 28 (29.3%) patients, the degree of stagnation in the small circle of blood circulation - in 5 (5.3%) patients. However, it was not possible to identify the source of LC, based on the data of survey and linear X-ray images. Thus, the informativeness of the screening radiological method of examination of patients with LC was 68.2%. Computed tomography (CT) was performed to clarify the diagnosis, localization and prevalence of the pathological process in 46 (48.1%) patients with LC. The informativeness of this research method was 98.94%. However, as a rule, CT was performed within the first week from the moment of admission, after bronchoscopy, and only in 9 cases urgently. All patients with LC of the main group underwent bronchoscopic sanitation for the purpose of hemostasis as the first stage. As a result of the performed complex hemostasis, grade I bleeding was stopped during the first procedure in 46 (94.1%) patients, while a single relapse was noted in only 3 (6.2%).
