ObjectivesTo 为 saphaneous 调查过程特征和经皮的冠的干预(一种总线标准) 的长期的后续在到 2011 年 12 月的老 patients.MethodsFrom 2005 年 12 月的静脉接枝(SVG ) 损害， 84 接枝损害经皮地被对待。十七在近似吻合被定位， 48 在 SVG 身体被定位， 19 在远侧的吻合被定位。主要端点被定义为主要不利心血管的事件(向，心脏的死亡合成，目标容器 revascularization，尖锐心肌的梗塞).ResultsThe 接枝年龄是 6.7 ±；4.0 年。在一年以内介绍的大多数吻合损害(80.0%) 张贴冠的动脉绕过 grafting (CABG ) 。近似吻合损害与接枝身体和远侧的吻合损害相比为一种总线标准有最低的成功的率(70.6% 对 91.7% ， 79.0% ， P <；0.05 ) 。远侧的插子的保护设备在 19.1% 病人被使用，最经常在身体接枝一种总线标准使用(29.2% ， P <；0.01 ) 。stent 的直径在远侧的吻合组是最小的(2.9 ±；0.4 公里， P <；0.05 ) 。最高的柱子膨胀压力在近似吻合被要求(17.8 ±；2.7 atm， P <；0.05 ) 。病人被跟随在上面为 24.3 ±；16.9 个月。向发生在 18.57% 病人。向的发生在近似吻合一种总线标准之中是最高的(47.1% 对身体接枝一种总线标准 16.7% ，远侧的吻合一种总线标准 21.1% ；P <；0.05 ) 。旧心肌的梗塞是为差的临床的结果的预兆的因素(P = 0.04 ) SVG 损害的 .ConclusionsPCI 与更低的成功是可行的率。ostial 接枝吻合损害的一种总线标准让最低过程成功率和最高的向与接枝身体和远侧的吻合损害相比评价。旧心肌的梗塞是差的结果的一个预兆的因素。
Objectives To investigate the procedure characteristics and long term follow-up ofpercutaneous coronary intervention （PCI） for sa phaneous vein graft （SVG） lesions in the elderly patients. Methods From December 2005 to December 201 l, 84 graft lesions were treated percumneously. Seventeen were located at proximal anastomosis, 48 were located at SVG body, 19 were located at distal anastomosis. Pri mary endpoint was defined as major adverse cardiovascular events （MACE, composite of cardiac death, target vessel revascularization, acute myocardial infarction）. Results The graft age was 6.7 i 4.0 years. Most anastomosis lesions （80.0%） presented within one year post coro-nary artery bypass grafting （CABG）. Proximal anastomosis lesion had the lowest successful rate for PCI compared with graft body and distal anastomosis lesions （70.6% vs. 91.7%, 79.0%, P 〈 0.05）. The distal embolic protection device was used in 19.1% of patients, most frequently used in body graft PCI （29.2%, P 〈 0.01）. The diameter of the stent was smallest in distal anastomosis group （2.9 ±0.4 mm, P 〈 0.05）. The highest post dilatation pressure was required in the proximal anastomosis （17.8 ± 2.7 atm, P 〈 0.05）. The patients were followed up for 24.3 ±16.9 months. MACE occurred in 18.57% of patients. Incidence of MACE was highest among proximal anastomosis PCI （47.1% vs. body graft PCI 16.7%, distal anastomosis PCI 21.1%; P 〈 0.05）. Old myocardial infarction was the predictive factor for the poor clinical outcomes （P〈 0.04）. Conclusions PCI of SVG lesions is feasible with lower success rate. PCI of ostial graft anastomosis lesions had the lowest procedure success rate and highest MACE rate compared with graft body and distal anastomosis lesions. Old myocardial infarction was a predictive factor of poor outcomes.
