Background. Thoracic surgical interventions in some patients are associated with a high risk of complications and mortality in the postoperative period, and may also be contraindicated due to functional limitations. Circumstances dictate the need to focus on methods of local impact on cavities in the lungs and residual cavities in the pleural space in order to quickly eliminate them, in particular, on endoscopic valvular broncoblockation (EVBB).
Objective. Assessment of the possibility of using endoscopic valvular broncoblockation in patients with pulmonary pathologies of various etiologies.
Methods. Radiological (radiography, fluoroscopy, multislice computed tomography) and endoscopic (tracheobronchoscopy, exploratory broncho-occlusion) methods, as well as their combination (selective bronchography) were used.
Results. In 110 cases, EVBB was performed to treat patients with destructive pulmonary tuberculosis, including in 58 cases with infiltrative tuberculosis, in 38 patients with disseminated tuberculosis and in 14 cases with fibrous-cavernous tuberculosis.
Conclusion. The use of an endobronchial valve in combination with PTCT is an effective non-drug method of treating patients with destructive pulmonary tuberculosis, which improves the results of their treatment and reduces the number of patients for whom surgical intervention is indicated.
