摘要 目的评价血管内超声(IVUS)在基层医院冠状动脉临界病变中的应用价值。方法对冠状动脉造影(CAG)提示单支冠状动脉临界病变的50例患者进行IVUS检查,根据IVUS面积狭窄率是否>50%分为介入治疗组及对照组。观察斑块的性状及IVUS有效管腔面积,并进行随访观察并发症。结果介入治疗组28例,对照组22例,介入治疗组斑块性状以纤维性斑块及脂质性斑块为主,介入治疗中无明显的并发症,随访1年,介入治疗组再发心绞痛3例,对照组发生心绞痛4例,心梗2例,猝死1例,两组比较差异有统计学意义(P<0.05)。结论 IVUS对临界病变的狭窄程度及指导介入治疗有一定的价值,对IVUS面积狭窄率≥50%的病变进行介入干预预后良好。
