中文摘要：

支气管动脉栓塞术是治疗咯血的有效方法之一.支气管动脉栓塞术主要适用于药物治疗无效的大咯血和反复咯血,对于药物治疗后咯血症状缓解的患者,如果术前评估考虑仍然存在大咯血复发风险,也应积极施行支气管动脉栓塞术.异位栓塞是支气管动脉栓塞术的主要手术并发症.大咯血的急诊手术具有非常高的手术风险,需积极防范和及时处理.

英文摘要：

Bronchial artery embolization is the first-line therapy to control massive hemoptysis or recurrent medium hemoptysis which is not response to hemostatics. For patients at high risk of massive hemoptysis, bronchial artery embo- lization should also be considered even though hemoptysis had stopped. The ectopic embolim is the most common compli- cation of bronchial artery embolization. An emergent operation to treat massive hemoptysis is very risky, therefore, it is crucial for prevention of risk and treatment for complications.
