摘　　要：目的　探讨无预扩张直接冠状动脉内支架置入术的可行性及临床效果。方法　参照国外直接冠状动脉内支架置入术标准 ,对 2 7例冠心病患者进行无预扩张直接冠状动脉内支架置入术。结果　 2 7例患者共 2 8处病变 ,置入 2 8个支架 ,其中 A型病变 14例 ,B1 型病变 10例 ,B2 型病变 4例。置入支架前管腔狭窄程度为 78.2 %± 5 .6% ,支架置入后血管残存狭窄程度为 0 .9%± 1.4% ,支架置入成功率为 10 0 % ,无并发症发生。术后随访 1年 ,2例患者出现心绞痛 ,冠状动脉造影证实 1例患者出现支架内再狭窄。结论　正确选择适应证的情况下 ,无预扩张直接冠状动脉内支架置入术是一种安全有效的治疗方法 ,可获得较好的近。Objectives To explore the feasibility and clinical efficacy of direct coronary stenting without predilation. Methods According to foreign criteria, intracoronary stents were directly deployed without predilation in 27 patients with coronary heart disease. Results Direct stenting was successful in 27 patients with 28 lesions, lesion type: type A ( n =14), type B 1 ( n =10) and type B 2 ( n =4). Pre-stenting luminal stenosis was 78.2±5.6%,post-stenting residual luminal stenosis was reduced to 0.9±1.4%,success rate of stent deployment was 100%, no complications occurred. During one year follow-up two patients had angina pectoris, only one of them had restenosis by coronary angiography. Conclusions Direct coronary stenting without predilation was a safe and feasible therapy in select patient correctly, obtaining better clinical results in short term and long term .
