205 and diagnostic measures for providing assistance to patients with PH. Some clinicians are supporters of conservative therapy, others are supporters of surgical treatment methods. The nature and duration of conservative therapy, as well as indications for urgent operations, are still being discussed. All of the above allows us to state that the problem of treating patients with PH is relevant, requires further scientific research and practical solutions. Keywords: Pulmonary hemorrhage, chronic bronchitis, bronchiectasis, diagnostics, surgical treatment, endobronchial occlusion The aim of the work was improving the results of diagnosis and surgical treatment of pulmonary hemorrhages of various etiologies. Pulmonary hemorrhage (PH) is a serious, often fatal complication of various, most often inflammatory, diseases of the respiratory system [1, p. 31]. For a long time, the most common cause of PH was pulmonary tuberculosis. In the last 20-30 years, PH has become more common in patients with nonspecific purulent-destructive lung diseases. Today, PH accounts for 1-4% of the total number of hemorrhages, while the mortality rate from this complication, which arose in connection with chronic nonspecific lung diseases, has reached 59-80% [2, p. 118]. Fatal cases of pulmonary hemorrhage are mainly due not to blood loss, but to asphyxia, even with a small amount of bleeding. The causes of PH can be various diseases and injuries of the chest and various organs and systems [3, p. 111, 4, p. 869, 5, p. 1354, 6, p. 75]. If the degree of LC can be assumed based on clinical examination methods, then diagnosing the cause of LC always causes great difficulties. The admission of a patient to the clinic with a diagnosis of LC always requires the immediate participation of doctors of various specialties for a comprehensive clinical and instrumental examination and the simultaneous implementation of a number of therapeutic measures aimed at preserving the patient's life [7, p. 2]. Unfortunately, at present there is no unified system of organizational and therapeutic and diagnostic measures for providing assistance to patients with LC.
