摘要 目的应用二维超声和超声造影成像技术评价脑梗死患者颈动脉斑块形态及声学特性与斑块内新生血管的关系。方法脑梗死组为104例急性脑梗死伴颈动脉粥样斑块患者,非脑梗死组为40例无临床脑梗死表现的颈动脉粥样斑块患者,经颈动脉二维超声检查获得斑块形态及声学特性分型,行超声造影检查获得斑块的造影参数进行定量分析评定。结果脑梗死组中软斑最多,其次混合斑;非脑梗死组混合斑最多,其次钙化斑。脑梗死组Ⅱ型斑块最多,非脑梗死组Ⅰ型斑块最多。脑梗死组超声造影增强率为81.1%(86/106),明显高于非脑梗死组(χ2=15.024,P<0.01),P、AUC明显高于非脑梗死组,Tp小于非脑梗死组斑块(t值分别为2.350、-3.041、2.839,P<0.05或P<0.01)。脑梗死组中,软斑及Ⅱ型斑块增强百分比最高,软斑P、AUC显著高于其他类型斑块(t=3.006~8.042,P<0.01),Tp小于其他类型斑块(t=-4.929、-2.513,P<0.01或P<0.05),MTT小于其他类型斑块,与硬斑比较差异有统计学意义(t=-3.994,P<0.01),与混合斑比较差异无统计学意义(t=-2.026,P>0.05)。Ⅱ型斑块P、AUC显著高于其他类型斑块,Tp明显小于其他类型斑块,差异均有统计学意义(t=-3.145~9.237,P<0.01)。Ⅱ型斑块MTT小于其他类型斑块,与Ⅰ型斑块比较差异有统计学意义(t=-4.537,P<0.01),与Ⅲ型斑块比较差异无统计学意义(t=-2.127,P>0.05)。结论超声造影能够方便地检测斑块内新生血管并进行定量分析,对斑块的稳定性做出更全面准确地评价,可以预测和早期诊断脑血管疾病,为临床早期干预、合理治疗脑血管疾病提供依据。
