应用ＨＤＩ型超９彩色声像仪，观察４１例老年脑梗死患者和４８例无脑梗死老年人（对照组）两侧颈总动脉内膜－中层厚度、斑块情况，两侧颈动脉和椎动脉颅外段内径、血流动力学改变。结果发现：（１）脑梗死组颈总动脉主干与分叉处内膜－中层厚度较对照组明显增厚，发现粥样硬化斑块３２例，占７８．０％；（２）脑梗死组颈总动脉、颈内动脉内径明显增宽；脑梗死组颈动脉和椎动脉颅外段舒张期末流速值、最高流速平均值较对照组明显降低；反映外周阻力的搏动指数、阻力指数，脑梗死组明显高于对照组。结果表明：老年脑梗死与颈动脉、椎动脉粥样硬化有关；颈动脉软斑块是可能发生潜在老年脑梗死的原因之一。
Using HDI super 9 color imager, we observed the intima-media thickness and plaque status of common carotid arteries in 41 elderly cerebral infarction patients and 48 elderly patients without cerebral infarction (control group). The carotid arteries and vertebrae Arterial extracranial diameter, hemodynamic changes. The results showed that: (1) Intima-media thickness of the common carotid arteries and bifurcation in patients with cerebral infarction was significantly thicker than that in the control group, 32 cases of atherosclerotic plaques were found (78.0%); (2) The diameter of common carotid artery and internal carotid artery obviously widened. The mean diastolic flow velocity and maximum velocity of extracranial segment of carotid artery and vertebral artery in cerebral infarction group were significantly lower than those in control group. The pulsatility index, resistance index, cerebral infarction Group was significantly higher than the control group. The results showed that the cerebral infarction was related to carotid artery and vertebral artery atherosclerosis. Carotid artery soft plaque was one of the possible causes of potential cerebral infarction.
