Abstract:

Objective To explore the effects of bronchial artery embolization(BAE) and conventional medical treatment on pulmonary function and arterial blood gas in patients with massive hemoptysis due to pulmonary tuberculosis, and to analyze related factors for recurrence after BAE.

Methods We retrospectively analyzed 78 patients with massive hemoptysis due to pulmonary tuberculosis who had failed conventional medical treatment. All patients were given BAE. The recovery of lung function and arterial blood gas indicators as well as the recurrence of massive hemoptysis and related risk factors were observed in all patients.

Results Among the 78 patients, 16 were cured, and the treatment was markedly effective in 30 patients, effective in 20 patients, and ineffective in 12 patients, with a total effective rate of 86.62%. The FVC, FEV, FEV/FVC and PaO2 of patients after conventional medical treatment were higher than those before treatment, while PaCO2 was lower than that before treatment; the FVC, FEV, FEV/FVC and PaO2 after BAE treatment were significantly higher than those before treatment and after conventional treatment, while PaCO2 was lower than that before treatment and after conventional treatment, with significant difference(P＜0.05). Of 78 patients, 26(33.33%) patients had a postoperative recurrence rate. Recurrence group had a higher rate of poor compliance, intense cough, cavitary tuberculosis, infection, poor postoperative activity, postoperative tension anxiety, GS embolization material and bronchiectasis than non-recurrence group(P＜0.05). Logistic regression showed that good treatment compliance, poor postoperative activity, and embolization material were risk factors for recurrence after massibve hemoptysis due to pulmonary tuberculosis(P＜0.05).

Conclusion BAE can improve the clinical efficacy in the treatment of massive hemoptysis due to pulmonary tuberculosis, accelerate the recovery of pulmonary function, and reduce hemoptysis. Poor treatment compliance, poor postoperative activities, embolization materials are risk factors for the recurrence of massive hemoptysis due to pulmonary tuberculosis after surgery, which should warrant attention.
