| 目的 探讨颈动脉粥样硬化与股动脉粥样硬化的超声诊断标准。方法 根据125例正常健康者颈动脉及股动脉超声图像,测量颈动脉及股动脉内径(D)、 颈动脉及股动脉内膜-中膜层厚度(IMT)、 颈动脉及股动脉僵硬度(β)和最大剪切率(SRs)。结果 随年龄增加,颈动脉及股动脉IMT、D、β呈增加趋势,SRs降低;正常人颈动脉和股动脉IMT分别为(0.63±0.15)mm、(0.68±0.21)mm,颈动脉及股动脉IMT上限分别为0.93mm、1.11mm。将正常人分为≥50岁组与<50岁组,颈动脉上限分别为1.09mm、0.85mm;股动脉上限分别为1.26mm、0.98mm。结论 正常人颈动脉及股动脉的IMT、血管内径和僵硬度随年龄增加而增加。采用IMT≥1.2mm可用于诊断颈动脉及年龄<50岁股动脉粥样硬化斑块,对于50岁以上患者,股动脉粥样硬化斑块诊断标准取IMT≥1.3mm较为合适。 |

| Objective To compare the intima-media thickness between the carotid and femoral arteries in normal subjects for establishing diagnostic criteria of atherosclerotic plaque. Methods The intima-media thickness (IMT), diameter (D), stiffness β and systolic SRs of the carotid and femoral arteries were measured by high resolution ultrasound. Results In carotid and femoral arteries, IMT, D and β increased with age increased, while SRs decreased. IMT in carotid and femoral arteries was (0.63±0.15)mm and (0.68±0.21)mm respectively,upper limit was 0.93mm and 1.11mm respectively. When the subjects were divided into age≥50 years group and age＜50 years group,value of upper limit in carotid IMT were 1.09mm, 0.85mm respectively. Value of upper limit in femoral IMT were 1.26mm and 0.98mm respectively. Conclusion That IMT≥1.2mm is defined as plaque is suitable to carotid artery or femoral artery with age＜50 years. It is more accurate to consider IMT≥1.3mm as a criteria of femoral plaque in age≥50 years. |
