冠状动脉长病变介入治疗114例分析

The therapeutic strategy of stent implantation for diffuse coronary lesions

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 。

Objective To evluate the effects of the single long stent and multiple contiguous coronary stents for the treatment of long lesions.Methods 114 cases were performed.According to the different approaches of stent implantation,114 cases of patients with successful operation were divided into two groups:group A with single long stent,group B with multiple contiguous stents.All patients received coronary artery angiography in order to evaluate the frequency of restenosis 6～10 months later.Results During hospitalization,there was no acute or subacute thermosis,no myocardial infarction and death.There was no difference in acute and long term results in the two groups.Conclusions The acute and long term outcome of both single long stent and multiple contiguous stents is satisfactory.There is no difference in the acute and long term outcome in the two groups.
