目的为评估经皮腔内冠脉成形术（PTCA）在治疗闭塞性冠状动脉病变的安全性与疗效。方法对19例冠状动脉闭塞病变行经皮腔内冠脉成形术(PTCA)。结果总成功率68.4％，完全闭塞病变的成功率与次全闭塞的成功率相似，慢性钙化病变的成功率（33.3％），显著低于非钙化病变（84.6％）；闭塞发生后1个月内行PTCA的成功率（88.9％）略高于1个月以后者（50％）；闭塞病变的长度及断端形态对成功率无显著影响。结论闭塞性冠状动脉病变的PTCA是安全有效的，闭塞时间越短PTCA成功率越高。%Objective To evaluate the safety and efficacy of PTCA in treating occlusive coronary artery disease. Methods 19 patients with occlusive coronary artery disease underwent PTCA and their results were analyzed. Results 68.4％ patients were succeeded, and the patients with completely occlusion had similar results to those with subtotal occlusion. Non－calcification lesions had better results than chronic calcification lesions. The success rate of those who received PTCA within one month after occlusion was slightly higher than that over one month (88.9％ vs 50％ ). Conclusion PTCA was safe and effective in treating occlusive coronary artery disease, especially when the occlusive time was short.
