【摘要】 目的 :探讨脑梗死与颈动脉粥样硬化的相关性。方法 :对 6 8例经CT、MRI证实的脑梗死患者的颈动脉颅外段进行彩色超声多普勒检查 ,观察颈动脉壁的病变性质和颈动脉管腔的狭窄率 ,并与对照组进行比较。结果 :6 8例脑梗死患者中有 5 6例 (82 .35 % )颈动脉颅外段存在不同程度的粥样硬化斑 ,与对照组比较差异有显著性(P <0 0 1) ;粥样硬化斑块好发于颈总动脉分叉处 (BIF) ,其次为颈内动脉起始部 (ICA) ;梗死灶同侧颈动脉粥样硬化较对侧严重 ,检出斑块与脑梗死部位存在显著同侧相关性 (P <0 0 1)。结论 :颈动脉粥样硬化与脑梗死的发生发展密切相关 ,并可作为预测及评价脑梗死的重要指标之一。更多还原

【Abstract】 Objective: To investigate the correlation between cerebral infarction and carotid arteriosclerosis. Methods:Colour ultrasonic Doppler examination was performed on the segment outside skull of the carotid in 68 patients with cerebral infarction confirmed by CT and MRI. The illness change character of the carotid wall and the narrowing rate of the carotid cavity were observed and compared with those in the control group. Results: Among the 68 patients, 56 cases (82.35 %) were found having various degrees of arteriosclerosis spots at the segment outside skull of carotid ( P <0.01); Arteriosclerosis spots were easily broken out at BIF, then at ICA; At the same side of the infarction, carotid arteriosclerosis was more serious than the other side, and there was the same side of correlation between the spots and cerebral infarction ( P <0.01). Conclusion:There is a close correlation between carotid arteriosclerosis and the development of the cerebral infarction. Carotid arteriosclerosis can be used as one of the importent indexes of forecasting and evaluating cerebral infarction.更多还原
