摘　　要：目的评价超声血管增强(VE)技术在颈动脉粥样硬化性狭窄(CAS)中的应用价值。方法 CAS患者70例,分别采用常规超声、彩色多普勒超声及VE技术检查颈动脉,测量颈动脉内径,计算狭窄率。结果 70例患者超声共检出CAS轻度65条,中度43条,重度15条,完全闭塞1条。本组患者颈动脉狭窄处内径VE测值[(3.61±1.19)mm]与常规超声测值[(3.79±1.02)mm]和CDFI测值[(3.88±1.06)mm]比较差异有统计学意义(P<0.05)。VE技术评估颈动脉轻、中、重度狭窄的敏感性分别为86.5%、77.8%、85.0%,特异性分别为94.8%、96.3%、95.5%。结论 VE技术能清晰显示颈动脉管腔和管壁结构,提高超声诊断颈动脉狭窄程度的准确性,具有较高的临床应用价值。Objective To explore the application of vascular enhancement（VE）technology in the diagnosis of carotid atherosclerotic stenosis（CAS）. Methods Seventy patients with CAS were examined by two-dimension,CDFI and VE. The carotid artery diameter were measured and percentages of stenosis were calculated. Rusults Sixty-five arteries with mild CAS, 43 with moderate CAS, 15 with serve CAS and 1 with complete occlusion were detected among seventy patients.The differences of CAS measurements between VE and two-dimension,CDFI were significant（P〈0.05）. The sensitivity and specificity of VE technology for the evaluation of CAS were 86.5%,77.8%,85.0% and 94.8%,96.3%,95.5%. Conclusion VE technology can show lumen and wall more clearly,thus improving the accuracy of ultrasonography in the diagnosis of CAS degree with a great value in clinic application.
