彩色多普勒超声检测颈动脉内中膜厚度、斑块及颈动脉狭窄对缺血性脑卒中的诊断价值

Value of color Doppler ultrasound for detections of carotid artery intima-media thickness, plaque and carotid artery stenosis in diagnosis of ischemic stroke

    摘要
  • 摘要:
      目的  探讨彩色多普勒超声检测颈动脉内中膜、斑块及颈动脉狭窄对缺血性脑卒中的诊断价值。
      方法  选取本院458例颈动脉超声检查对象, 其中对照组168例为非脑卒中健康体检者，卒中组290例为缺血脑卒中患者。分析2组颈动脉内中膜增厚、斑块及不同狭窄程度发生率。
      结果  卒中组颈动脉内膜中层厚度(IMT)增厚发生率、颈动脉斑块的发生率与对照组比较有显著差异(P < 0.05), 卒中组颈动脉狭窄程度显著高于对照组(P < 0.05)。
      结论  颈动脉内中膜增厚、斑块及狭窄程度与缺血脑卒中密切相关，颈动脉超声可有效提高脑卒中检出率。

     

    Abstract:
      Objective  To explore the value of color Doppler ultrasound for detections of carotid intima-media thickness, plaque and carotid stenosis in diagnosis of ischemic stroke.
      Methods  Totally 458 patients with carotid artery ultrasonography were selected and divided into control group (n=168, non-stroke health controls) and stroke group (n=290, ischemic stroke patients). The incidence rates of carotid artery intima-media thickness, plaque and different degrees of stenosis were analyzed in both groups.
      Results  There were significant differences in incidence rates of carotid intima-media thickness (IMT) thickening and carotid plaque between stroke group and control group (P < 0.05), and the degree of carotid stenosis in stroke group was significantly higher than that in control group (P < 0.05).
      Conclusion  Carotid intima-media thickness, plaque and stenosis degree are closely related with ischemic stroke. Carotid ultrasound can effectively increase the detection rate of stroke.
