ABSTRACT
OBJECTIVE: To investigate the long-term effect and the key factors associated with relapse of double embolization of bronchial artery in patients with lung tuberculosis and hemoptysis. METHODS: Fifty patients with lung tuberculosis and hemoptysis receiving the radiography and double embolization of bronchial artery (BAG + BAE) had been followed up for two years. The causes for hemoptysis relapse was determined, followed by specific treatment, and the effect was evaluated. Among them, 37 were males, 13 females, with the age of 8-75 years (mean age 47.6 years). RESULTS: The 2 year follow-up showed that the cure rate and the effective rate were 62% (31/50) and 94% (47/50) respectively. In a short term after embolization, hemoptysis relapsed in 9 cases, the major causes being active tuberculosis and secondary bronchiectasis complicated with infection. Other responsible factors included missed-embolization of bronchial artery and remaining blood supply from systemic circulation. In mid and long term follow-up, hemoptysis relapsed in 10 cases, the major causes being secondary pulmonary mycotic infection and recurrence of tuberculosis. CONCLUSIONS: The long term result of double embolization of bronchial artery in patients with lung tuberculosis and hemoptysis was significant. It could prevent the danger from massive hemoptysis, and therefore allows the medical therapy for tuberculosis. Embolization of bronchial artery is effective for hemostasis, while etiologic therapy aimed at removing the infection leading to chronic inflammation is the cure for tuberculosis and hemoptysis.
