支气管动脉栓塞术的临床应用研究

目的：探讨支气管动脉栓塞术临床应用的可行性，适应证，禁忌证以及掌握关键技术环节，避免并发症。材料与方法：61例支气管动脉栓塞患者，肺癌32例，肺结核并大咯血21例。支气管扩张咳血6例，支气管动静脉瘘2例。使用无水乙醇作为栓塞剂28例，使用明胶海绵26例，另7例是无水乙醇 明胶海绵和微球 明胶海绵。栓塞剂的量视病灶而定。结果：超选择插管38例，插管成功率100％，肺癌支气管动脉栓塞后总有效率87．5％，大咯血栓塞后的止血总有效率92％(26／27例)。有2例出现不同程度的脊髓动脉损伤症状。结论：支气管动脉栓塞技术是一种行之有效的治疗方法；致死性大咯血内科治疗无效时应尽早行介入治疗，见有脊髓动脉显影应视为绝对禁忌症。

Clinical Application Study of Bronchial Artery Embolization

Purpose: To investigate the feasibility, applicability and contraindication of bronchial artery embolization in treatment of lung disease. Marterial and Methods: Bronchial artery embolization was performed in 61 patients (pulmonary carcinoma 32 cases; hemoptysis of pulmonary tuberculosis 21 cases hemoptysis of bronchiectasis 6 cases, bronchial arteriovenous malfomation 2 cases) . The hemostatic agents included ethanol in 28 cases, Geifoam in 26 cases, ethanol plus Geifoam pellet in 7 cases. Results: The super-selective intrabronchialarterial intervention was performed in 38 cases, and succees rate of superselective intervention was 100% . Affer bronchial artery embolization with lung cancer, effective rate was 87.5% . Hemoptysis was controlled completed in 26 patients (effective rate was 92%) . Conclusion: Embolization of bronchial artery is effective method and embolization of bronchial artery must be enforced for controlling refractory or massive hemoptysis. It is a contraindication of bronchial artery embolization to appear spinal cord artery.
