老年脑梗死与颈动脉粥样硬化关系的研究

目的通过对颈动脉内中膜厚度的检测,以探讨颈动脉粥样硬化病变发生率与脑梗死的关系.方法采用B型超声测定颈动脉内中膜厚度和粥样硬化斑块指数.检测130例,脑梗死组65例,对照组65例.结果在脑梗死组颈动脉内中膜厚度明显大于对照组(P＜0.01),颈动脉管腔直径两组无显著性差异.动脉粥样硬化斑块检出率在两组中均以球部为最高,其次为颈总动脉和颈内动脉.脑梗死组颈总动脉硬化发生率、颈动脉硬化斑块指数均显著高于对照组(P＜0.01).结论颈动脉粥样硬化严重程度与脑梗死发生率呈正比.

STUDY ON THE CORRELATION BETWEEN SENILE CEREBRAL INFARCTION AND CAROTID ARTERY ATHEROSCLEORSIS

Objective To explore the correlation between senile cerebral infarction and carotid atheroscleorosis by detecting media thickness in carotid artery.Methods B-mode ultrasonography was used to measure media thickness in carotid artery in65 cases of cerebral infarction and in other 65 cases in the contrast group.Results The thickness of carotid endangium in the cerebral infarction group was found to be greater than that of the contrast group (P<0.01),while no significant differences were discovered between the diameters of the two groups.The detection rate of carotid artery arteriosclerosis psoriasis was highest at the sphere,then in the common and internal carotid arteries in both groups.The incidence rates of common carotid artery atherosceleosis and the indexes of carotid endangium artery psoriasis were both higher in the cerebral infarction group than in the contrast group (P<0.01).Conclusion The degree of carotid atheroscleorsis is in direct proportion to the incidence rate of cerebral infarction.
