Аssessment of segmental bronchial blocking success in the comprehensive treatment of patients with destructive pulmonary tuberculosis

Abstract

The experience of using bronchial valve placement in em- physema treatment and studies on the effect of collateral ventilation in lobar bronchial blocking cast doubt on the effectiveness of this technique at the level of segmental bronchi using a single blocker. The aim of the study is to evaluate the effectiveness of segmental valve placement in the comprehensive treatment of patients with de- structive pulmonary tuberculosis. The study is based on the results of evaluation of chest CT data of patients with destructive forms of pulmonary tuberculosis before and after valve placement. The correlations between the se- lected features were assessed and a model for predicting the cavity closure was built. A statistically significant cor- relation was found between the change in the segment
volume after valvular blocking and the closure of the de- struction cavity. As a result, the low efficiency of segmen- tal valve placement in the comprehensive treatment of patients with pulmonary tuberculosis was revealed.
