为观察直接冠状动脉内支架植入术的可行性和临床效果 ,对 2 3例冠心病患者行未预扩张直接冠状动脉内支架植入术 ,同期与按传统方法预先用球囊扩张后再植入支架的 2 4例冠心病患者进行对比 ,观察其即刻和远期效果。结果显示 :两组病例的手术即刻成功率均为 10 0 % ,而未预扩张组的不良心脏事件 (心绞痛、心肌梗塞、心性死亡 )的发生率较预扩张组低。提示对恰当选择的冠状动脉病变直接植入支架具有较高的即刻成功率和较理想的远期效果
In order to observe the feasibility and clinical effect of direct coronary stent implantation, direct coronary stent was performed on 23 patients with coronary artery disease without pre-expansion. In the same period, 24 cases of coronary heart disease into the stent were compared to observe its immediate and long-term effects. The results showed that the immediate success rate of surgery in both groups was 100%, while the incidence of adverse cardiac events (angina pectoris, myocardial infarction, cardiac death) in the non-pre-dilatation group was lower than that in the pre-dilatation group. Suggesting that the immediate success rate and the more desirable long-term effect of directly implanted stents on properly selected coronary lesions
