目的:观察急诊介入栓塞治疗支气管动脉-肺动脉瘘大咯血患者的疗效,分析栓塞剂的选择及合理应用,为临床研究提供参考。方法:30例支气管动脉-肺动脉瘘大咯血患者采用急诊介入造影检查,使用丙烯酸微球和明胶海绵条对出血动脉行急诊栓塞治疗,对动脉造影表现及治疗结果进行回顾性分析。结果:共找到并成功栓塞42支出血的支气管动脉,28支采用单独丙烯酸微球栓塞治疗,14支行丙烯酸微球与明胶海绵条联合栓塞治疗。栓塞术后随访1年,所有患者栓塞术后均无再次咯血及严重并发症出现。结论:急诊动脉栓塞治疗支气管动脉-肺动脉瘘大咯血是一种安全、有效的微创治疗手段。合理的选择和使用栓塞剂是确保栓塞治疗成功的的关键。 OBJECTIVE: To observe the efficacy of emergency interventional embolization in the treatment of patients with massive hemoptysis of bronchial artery-pulmonary fistula, analyze the selection and rational application of embolic agents, and provide reference for clinical research. Methods: Thirty patients with massive hemoptysis of bronchial artery - pulmonary fistula were treated with emergency interventional angiography. Acrylic microspheres and gelatin sponge were used to perform emergency embolization of the bleeding artery. The angiographic findings and treatment outcome were retrospectively analyzed. Results: Forty-two bronchial arteries were successfully embolized, 28 were treated with acrylic microsphere embolization, and 14 were treated with acrylic microspheres and gelatin sponge. Followed up for 1 year after embolization, all patients had no recurrence of hemoptysis and severe complications after embolization. Conclusion: Emergency arterial embolization is a safe and effective minimally invasive treatment of bronchial artery-pulmonary fistula. Reasonable choice and use of embolic agent is the key to ensuring the success of embolization.
