Analysis of risk factors for recurrence within 6 months after bronchial artery embolization for massive hemoptysis due to pulmonary tuberculosis.

This study aims to investigate the causes and risk factors of recurrence within 6 months after transcatheter bronchial artery embolization for massive hemoptysis in pulmonary tuberculosis. A retrospective observational study was conducted on the clinical data of 237 patients with pulmonary tuberculosis and massive hemoptysis who relapsed within 6 months after bronchial artery embolization. Univariate analysis was first conducted to screen for risk factors with statistical significance, and then multivariate logistic regression analysis was performed to infer the risk factors that might lead to the recurrence of hemoptysis.
