目的 探讨应用缠绕型和管型冠状动脉内支架治疗冠心病的效果。方法 对 2 3例冠心病患者根据不同情况植入冠状动脉内支架 ,其中DeNovo支架 17个 ,Suboptimal支架 6个 ,Bail-out支架 2个。结果 2 3例患者 2 5支血管植入 2 5个冠状动脉内支架。其中缠绕型支架 9个 ,包括Gianturco -Robin支架2个 ,XT支架 7个 ;管型支架植入 16个 ,均为NIR支架。植入前降支 15个 ,回旋支 2个 ,右冠状动脉 8个。所有支架植入均获得成功。 3例心绞痛复发的患者经造影证实为再狭窄 ,其中XT支架 1个 ,NIR支架 2个 ,总的再狭窄率为 12 % ,缠绕型和管型支架的再狭窄率分别为 11%和 12 .5 %。结论 冠状动脉内支架为治疗PTCA术后急性冠状动脉闭塞、降低再狭窄率的有效措施 ;根据不同的病变合理选择缠绕型和管型支架可提高支架植入的成功率 ,减少并发症。
Objective To investigate the application of wound-type and coronary stent in the treatment of coronary heart disease. Methods Twenty-three patients with coronary heart disease underwent coronary stent implantation. There were 17 DeNovo stents, 6 Suboptimal stents and 2 Bail-out stents. Results Twenty-five patients underwent 25 intracoronary stents with 25 vessels. Including wound-type stent 9, including two Gianturco-Robin stent, XT stent 7; tube stent implantation 16, are NIR stent. 15 anterior descending artery, 2 gyrus and 8 right coronary arteries. All stents were successfully implanted. Three patients with recurrent angina were confirmed by contrast-enhanced radiography. There were 1 XT stent and 2 NIR stent. The total restenosis rate was 12%. The restenosis rates of wound and stent were 11% and 12% respectively. 5%. Conclusion Coronary stent is an effective treatment for acute coronary occlusion and reduce restenosis rate after PTCA. Depending on the lesion, the reasonable choice of wound type and stent can improve the success rate of stent implantation and reduce the complications.
