微导管在支气管动脉栓塞术中的临床应用

目的：评价微导管在支气管动脉灌注栓塞治疗中晚期肺癌及大咯血的临床应用价值。方法：用微导管超选择性支气管动脉灌注栓塞治疗中晚期肺癌52例及肺大咯血20例。结果：全部病例超选择性插管成功，成功率100％，治疗后肺癌组完全缓解(CR)8例；部份缓解(PR)32例；稳定(S)12例；进展(P)0例；术后1，2，3a生存率分别为100％，75％，40％。咯血组BAE术后即期止血16例，显效4例，无效0例，总有效率100％；全部病例均未出现并发症。结论：在支气管动脉栓塞术中应用微导管安全，可避免并发症的发生。

Clinical Application of Microcatheter Superselective Bronchial Artery Embolization

Objective: To evaluate the value of microcatheter superselective bronchial artery enbolization (SBAE) treating advanced bronchogenic carcinoma and massive hemoptysis. Methods: 52 patients with advanced bronchogenic carcinoma and 20 patients with massive hemoptysis were performed by SBAE respectively. Results: The catheterization was successful in all procedures (100%). The total effective rate of treating bronchogenic carcinoma was 100%. The survival rate at 1,2,3 years was 100%, 90%, 40% respectively. Immediate and complete control of hemoptysis was achieved in 15 patients. Marked reduced bleeding was seen in 5 patients. No serious complication occurred in all patients. Conclusion: Microcatheter for superselective bronchial artery embolization is an effective and safe procedure for treating advanced bronchial carcinoma and controlling massive hemoplysis and complications can be avoided.
