先期近端优化技术改善分叉病变双支架术的预后

Preproximal optimization technique improves outcome of bifurcate lesions after implantation of two stents

目的探讨先期近端优化技术(POT)能否常规应用于各种分叉病变双支架术.方法选择我院近3年接受双支架治疗的分叉病变患者386例,根据是否采用先期POT,分为先期POT组178例[先期POT结合常规对吻球囊扩张(KBI)]和KBI组208例.观察2组1年不良心血管事件、KBI成功率及效率.结果在随访期内,先期POT组不良心血管事件发生率(11.2% vs 19.7%,P=0.03)和再次靶血管重建率低于KBI组(7.3% vs 13.9%,P=0.04),KBI成功率明显高于KBI组(98.3%vs88.5%,P=0.00).结论先期POT结合KBI,能提高KBI成功率及操作效率,使双支架术治疗分叉病变获得更佳临床预后.

Objective To study the application of preproximal optimization technique(pre-POT)in treatment of bifurcate lesions after implantation of two stents.Methods Three hundred and eighty-six bifurcation lesions patients who underwent implantation of two stents in our hospital were divided into pre-POT group(n=178)and kiss balloon inflation(KBI)group(n=208).The 1-year incidence of MACE ,the success rate and efficiency of KBI were retrospectively analyzed. Results The incidence of MACE was significantly lower in pre-POT group than in KBI group during the follow-up period(11.2% vs 19.7%,P =0.03).The revascularization rate of target lesions was significantly lower while the success rate was significantly higher in pre-POT group than in KBI group(7.3% vs 13.9%,P =0.04;98.3% vs 88.5%,P =0.00).Conclusion pre- POT combined with KBI seems to improve the success rate and efficiency of KBI and achieve the better outcome of bifurcate lesions after implantation of two stents.
