1、DSA冠状动脉造影在冠状动脉病变诊断中的价值作者:肖榜喜 钟燕青 郑浈浈【关键词】冠状动脉 摘要:目的:分析86例冠状动脉造影(CAG)的诊断结果,评价DSA―CAG对冠状动脉病变的诊断价值。方法:应用DSA选择性CAG证实病变≥50%直径狭窄病例63例,依病变狭窄程度累及冠状动脉部位、数目、形态、冠状动脉优势状况、侧支循环及心肌梗死病例、左室壁运动情况和射血分数(EF)等进行统计分析。结果:50%狭窄或闭塞63例(73%)冠状动脉右优势型41例(66%),左优势型7例(11%)均衡型12例(20%),单支病变22例(36%)双支病变17例(27%),3支病变20例(32%)受累血管104
2、支136处,重度狭窄及闭塞28处(45%),12例(19%)有不同程度侧支循环形成,32例做了左心室造影射血分数(LVEF)及室壁运动缩率分析,EF≥50%的20例(66%),EF40%~50%的7例(22%),<40%2例(7%),经统计学分析,严重冠状动脉狭窄与闭塞合并室壁瘤者与单纯狭窄病变LVEF差异有极显著意义(P<0.01)。结论:冠状动脉循环与分布多数为右优势型,冠状动脉病变多累及前降支(LAD),其次为右冠状动脉(RCA)及左回旋支(LCF),病变程度多为严重狭窄,侧支循环形成良好者对左心室功能有保护作用,高质量的DSA设备是开展冠心病介入的重要基础,DSA-CAG对冠状脉病变
