支气管动脉栓塞术治疗大咯血的疗效研究

目的：探讨支气管动脉栓塞术治疗急症大咯血的近远期疗效及术后咯血复发、影响该治疗技术疗效的主要原因。方法：对57例大咯血患者行支气管动脉栓塞术治疗。57例中，支气管扩张症20例，肺结核31例，肺癌6例。术后随访3～18个月，观察疗效。结果：即刻止血48例（84．2％），术后咯血完全停止；7例咯血明显减少，经内科保守治疗2—5天后咯血停止；2例咯血减少不明显，经二次栓塞治疗后咯血停止。2例肺结核患者及1例肺癌患者术后因病情进展，分别于6个月、9个月后再次咯血，经再次栓塞治疗后咯血停止。结论：支气管动脉栓塞术治疗急症大咯血创伤小，止血迅速安全，近远期疗效确切，有效控制原发病可降低咯血复发率。

Study of efficacy of bronchial artery embolization in treatment of severe hemoptysis

Objective：To investigate the short-term and long-term efficacy and the key factors associated with relapse of bronchial arte- rial embolization （BAE） in the treatment of severe hemoptysis. Methods： Bronchial arterial embollzation was performed in 57 patients （bronchiectasis 20 cases, pulmonary tuberculosis 31 cases, lung cancer 5 cases）. All cases were followed up for 3 - 18 months to observe the clinical efficacy. Results： Hemoptysis was completely controlled immediately affter BAE in 48 cases（84.2 % ）, alleviated in 7 cases, 2 were completely controlled by BAE again. Hemoptysis was recurrent in 2 patients with pulmonary tuberculosis 6 months later and in 1 patient with lung cancer 9 months later. All cases were completely controlled by BAE again. Condu.sion： BAE is a less invasive, effective, safe and simple method to controll hemoptysis. Controlling the primary disease can effectively reduce recurrence.
