【摘要】目的 探讨64层CT血管造影(CTA)对颈动脉斑块检查的临床价值.方法 分析2008年1月至8月我院116例颈动脉粥样硬化患者的CTA资料.结果 共发现377个斑块,其中斑块钙化率63.加%;颈动脉斑块多见于颈总动脉(27.85%)、颈动脉分叉部(39.78%)及颈内动脉(21.48%).轻度与中度及重度狭窄组斑块构成的差异有统计学意义(P=0.000).≤50岁与≥70岁组间斑块类型差异有统计学意义(P=0.005).颈总动脉发生斑块的类型与颈动脉分叉部及颈内动脉间差异有统计学意义(P=0.000).逐步回归分析显示血管闭塞与临床症状正相关(B=1.080,P<0.05),而钙化性斑块与临床症状负相关(B=-0.688,P<0.05).结论 64层CTA不仅可评价颈动脉斑块的影像特征,还可定量测量血管狭窄;联合评价斑块类型、狭窄程度及发生的血管节段可对临床脑血管事件作出预测.%Objective To explore clinical significance of muhidetector(64-row)computed
