【摘要】 目的：探讨颈动脉粥样硬化及其危险因素与不同类型的脑梗死间的关系。方法：根据头颅ＣＴ或ＭＲＩ结果，将１８８例脑梗死患者分成四个亚组：皮层梗死组（ＣＩ），皮层下梗死组（ＳＣＩ），椎—基底动脉支配区梗死组（ＶＢＡＩ）及心源性脑栓塞组（ＣＥＩ），用彩色多普勒超声（彩超）对各型脑梗死患者颅外颈动脉粥样硬化严重程度进行评估，并对可能危险因素进行探讨。结果：３０％的ＣＩ组患者，１０％ＣＥＩ患者，６．９％ＶＢＡＩ患者及７．９％ＳＣＩ患者有严重颈动脉狭窄，ＣＩ亚组斑块积分（ＰＳ）及脂蛋白（α）水平明显高于其它亚组，ＣＩ亚组糖尿病患者较多，ＣＥＩ亚组左室肥大较其它亚组常见，各亚组其它危险因素比较则无显著性差异。多元线型回归发现：斑块积分与年龄、男性、糖尿病、胆固醇及脂蛋白（α）水平、胰岛素／血糖比值密切相关。结论：皮层梗死患者颅外颈动脉粥样硬化比其这它类型脑梗死患者严重，皮层梗死患者严重颈动脉狭窄较为常见，而皮层下梗死患者严重颈动脉狭窄较少见。年龄、男性、糖尿病、高胆固醇血症、脂蛋白（α）水平、胰岛素抵抗是颈动脉粥样硬化的危险因素。更多还原
