冠状动脉闭塞病变介入治疗的临床研究

目的：探讨冠状动脉闭塞经皮冠状动脉腔内成形术（PTCA）治疗的效果。方法：对23例行PTCA及支架置入患者进行临床分析。结果：23例患者PTCA及置入支架后24支闭塞血管18支被开通，血管病变开通成功率72．0％，病例成功率78．3％（18／23），闭塞病变时间〈3个月组的患者成功率92．3％，明显高于闭塞病变时间〉3个月组的患者54．5％（P〈0．01）。结论：冠状动脉完全闭塞病变患者行PTCA及置入支架治疗是安全可行的，血管闭塞的时间和病变局部形态特征是手术成功的重要因素。

Clinical research of interventional treatment for coronary artery occlusion

Objective: To inquire the effect of percutaneous transluminat coronary angioplasty ( PTCA) for coronary artery occlusion. Methods: Investigated and analized the affected factors and results of 23 cases with PTCA and intracoronary stent of coronary artery occlusions. Results: 18 occluded branches were successfully revascularized in 23 cases with 24 occlusion branches. The lesion success rate was 72. 0 % (18/24) , while the case success rate was 78. 3 % ( 18/23) . The case success rate was 92. 3 % in patients with an occlusion duration of < 3 months, and it was obviously higher than patients with occlusion duration of > 3 months (54. 5 % ) (P<0.01). Conclusions:It is feasible and safe for coronary artery occlusion treating by PTCA and intracoronary stent The important affected factors of success are occluded duration and lesion morphologic characteristics.
