目的 比较单个长支架和多个支架相连的方法治疗冠状动脉长病变的近、远期效果。方法 回顾性分析接受经皮冠状动脉球囊扩张 +支架植入术 (PTCA +Sent)治疗的冠状动脉长病变 (>2 0mm)患者的临床资料 ,根据支架植入数量和方法分为两组 :A组 :靶病变 (单个长支架 ) 79个 ,B组 :4 6个 (2～ 3个支架相邻接 ) ,所有患者术后 6～ 1 0个月复诊并查冠状动脉造影 ,评价近、远期效果。结果 1 1 4例患者手术成功 ,围手术期内无急性、亚急性血栓形成 ,无急性心肌梗死发生 ,无死亡。随访观察 1年 ,无论采用单个长支架还是多个支架相连的方法治疗冠状动脉长病变 ,两者的远期死亡率、再狭窄率和心血管事件发生率均无显著性差异。结论 介入治疗冠状动脉长病变 ,其近、远期结果均满意。无论单个长支架还是多个支架相连 ,两种方法的近、远期结果是一致的。选择支架应着重考虑靶血管和靶病变的特点 ,这样既可提高手术成功率和安全性 ,又可减少相关的手术费用
Objective To compare the short-term and long-term effects of a long stent combined with multiple stents in the treatment of long coronary lesions. Methods The clinical data of patients with long coronary lesions (> 20 mm) undergoing percutaneous coronary balloon dilatation and stent implantation (PTCA + Sent) were retrospectively analyzed. According to the number and method of stent implantation, the patients were divided into two groups: In Group A, there were 79 target lesions (single long stent) and 46 in Group B (adjacent to 2 to 3 stents). All patients were referred for coronary artery angiography at 6-10 months postoperatively and coronary angiography was performed. Long-term effect. Results 1 1 4 cases of successful surgery, perioperative no acute and subacute thrombosis, no acute myocardial infarction, no death. One year follow-up showed no significant difference in the long-term mortality, restenosis rate and incidence of cardiovascular events between the two groups. No difference was found in the long-term coronary artery disease whether single long stent or multiple stents were connected. Conclusion Interventional treatment of long coronary lesions, the near and long-term results are satisfactory. Regardless of a single long stent or multiple stents connected, the two methods of near and long-term results are consistent. Select the stent should focus on the target vessel and the target lesion characteristics, so that both can improve the success rate and safety of surgery, but also reduce the associated surgical costs
