目的探讨使用明胶海绵颗粒等材料栓塞支气管动脉治疗临床咯血的效果、意义及方法。方法咯血患者21例,选择性插管至患侧支气管动脉,注入明胶海绵颗粒等栓塞材料,观察止血效果。结果1例患者于20h再次出现大咯血,再次插管栓塞另一支气管动脉,咯血停止。另2例患者少量间断咯血1～3d,经内科保守治疗,停止咯血。其余病例未再出现咯血。结论使用明胶海绵颗粒等材料栓塞支气管动脉治疗临床咯血是安全、有效的方法。 Objective To investigate the effect, significance and method of embolization of bronchial artery with gelatin sponge particles in the treatment of clinical hemoptysis. Methods 21 cases of hemoptysis, selective intubation to the ipsilateral bronchial artery, injection of embolic material such as gelatin sponge particles, to observe the effect of hemostasis. Results One patient presented with massive hemoptysis again at 20h. The other bronchial artery was cannulated again and the hemoptysis stopped. The other 2 patients a small amount of intermittent hemoptysis 1 ~ 3d, conservative treatment by internal medicine, stop hemoptysis. The remaining cases no longer appear hemoptysis. Conclusion The use of gelatin sponge particles embolization of bronchial artery treatment of clinical hemoptysis is a safe and effective method.
