摘要 目的评价支架增强显影技术(SB)在老年冠脉介入患者中的应用价值。方法 2011年10月至2013年3月行冠脉介入治疗(PCI)老年患者102例为观察组,在冠状动脉造影定量分析(QCA)基础上,应用SB进行支架可视性评价和支架后扩张必要性评价;同期进行冠脉介入的老年患者102例作为对照组,单纯应用QCA冠状动脉造影定量分析进行支架可视性评价和支架后扩张必要性评价。通过标准的QCA和SB对支架可视性进行评价并分为1~4级(1级=差,2级=可,3级=良,4级=优)。经QCA定量分析、SB对球囊后扩张的必要性进行评价(球囊后扩张必要性:0=支架贴壁良好不需要后扩张;1=支架贴壁可,不需要后扩张;2=支架贴壁不良,需要后扩张)。结果 QCA显示支架可视性为(2.03±0.84)级(其中1级40个,2级71个,3级32个,4级8个),SB显示支架可视性为(2.79±0.84)级(其中1级14个,2级32个,3级82个,4级28个),两者相比,差异有统计学意义(P<0.05)。根据QCA定量分析结果行球囊后扩张30次,根据SB评价结果行球囊后扩张48次,两者相比,差异有统计学意义(P<0.001)。结论 SB可明显提高支架的可视性,有效指导支架的后扩张,在不增加手术时间和费用的基础上可能降低支架血栓形成的风险。
