指引导管深插技术在冠状动脉复杂性病变中的应用

THE USE OF DEEPLY-INSERTING-GUIDING TECHNIQUE IN COMPLICATED CORONARY LESIONS

目的评价指引导管深插技术在冠状动脉复杂性病变中的应用效果.方法选择2002年1月～2003年10月在我院治疗的23例25支复杂性病变冠状动脉,其中完全闭塞血管3支,次全闭塞血管22支;病变血管均属C型病变,长度＞1 cm,均采用导管深插介入技术进行治疗.结果 25支血管均成功完成了经皮冠状动脉成形术联合支架安置术.其中3支血管出现并发症,发生率12%.结论对冠状动脉复杂性病变使用导管深插技术进行介入手术,成功率高,并发症发生率低.

Objective To evaluate the therapeutic efficacy of deeply-inserting-guiding technique in complicated coronary lesions. Methods The technique was used in 23 patients with 25 complicated coronary artery lesions, which included chronic total occlusion （3 cases）, and sub-total occlusion （22）. All the lesions were type C lesions, and longer than lcm. Results PTCA and Stent was done successfully on 25 arteries. Complications occurred in three arteries （12%）. Conclusion Deeply-insertingguiding technique in complicated coronary lesions can improve success rate, and lower the complications.
