| 目的 探讨颈动脉粥样硬化与缺血性脑血管病的关系。方法 彩超检测130例缺血性脑血管病患者的颈动脉,测量颈总动脉后壁IMT,观察斑块的有无及形成情况;并检查非缺血性脑血管病患者73例作为对照组。结果 脑梗死组及TIA组IMT与对照组相比有显著性差异(P< 0.01)。130例缺血性脑血管病患者中,颈动脉有粥样硬化、斑块形成等血管异常者112例,异常检出率为86.15%;对照组中有斑块形成19例,异常检出率为26.0%,两者比较有显著性差异(P<0.01) 。颈动脉粥样硬化斑块最常见于颈动脉分叉处,其次为颈内动脉起始段,但左右侧间差异无显著性(P>0.05)。结论 缺血性脑血管病患者的颈动脉粥样硬化程度明显重于非脑血管病患者,颈动脉粥样硬化的不稳定性斑块脱落是造成脑梗死的重要发病原因之一。彩超技术对颈动脉粥样硬化斑块的检出预测和疗效观察有重要意义。 |

| Objective To study the relationship between atherosclerosis of the common carotid artery and ischemic cerebrovascular disease.Methods Color Doppler ultrasonography of the carotid arteries was performed on 130 patients with ischemic cerebrovascular diseases. The maximum IMT of the posterial wall at distal common carotid artery and plaques in 130 patients were measured and compared with 73 healthy controls.Results IMT were significantly increased in CI group and TIA group versus control subjects (P<0.01). The abnormal appearances of carotid arteries such as atherosclerosis,intima-media thickening and plaque formation were found in 112 of 130 patients with ischemic cerebrovascular disease and the rate of total lesion detection was 86.15%. Nineteen cases with intima-media thickening and soft plaque formation were detected in the control group and the rate of lesion detection was 26%. There was significant difference between the two groups (P<0.01).The most common site of plaque formation is the bulb of the common carotid artery,and than proximal internal carotid artery. There was no difference of occurrence rate between right and left.Conclusion The severity of atherosclerosis of carotid artery in CI group and TIA group is higher than control group. One cause of cerebral infarction is from soft plaque broken in carotid artery. Color Doppler ultrasonography is an important technique in detecting atherosclerosis of the carotid artery,assessing potential occurrence of ischemic cerebral disease and evaluating the effect of treatment with medication or surgery. |
