颈动脉粥样硬化与脑梗死复发的关系研究

目的:分析颈动脉粥样硬化与脑梗死复发的关系。方法:采用彩色多普勒超声对282例急性脑梗死患者的颈动脉进行检测,随访观察脑梗死复发情况,脑梗死复发者计入复发组,无脑梗死复发者计入对照组。结果:随访1年,282例脑梗死患者中31例(10.99%)出现脑梗死复发,复发组颈动脉粥样硬化不稳定斑块的检出率和颈动脉内膜中层厚度值高于对照组(P<0.05)。结论:颈动脉粥样硬化不稳定斑块和颈动脉内膜中层厚度增加的患者脑梗死的复发率高。

The relationship between carotid atherosclerosis and recurrence of cerebral infarction

Objective To analysis the relationship between carotid atherosclerosis and recurrence of cerebral infarction.Methods Carotid atherosclerosis was assessed using Doppler ultrasonography in 282 patients with acute cerebral infarction(ACI).All patients were followedup prospectively and the outcome of recurrence of cerebral infarction was observed.The patients with the recurrence of cerebral infarction were classified into the relapse group,the patients without recurrence of cerebral infarction were clasified into the control group.Results Among 282 patients with ACI,31 patients had recurrence of cerebral infarction(10.99%) in 1 year follow-up period.The detection rate of carotid atherosclerosis unstable plaque and the value of carotid intima-media thickness(IMT) in the recurrence group are higher than that in the control group(P<0.05).Conclusion The patients with unstable plaque and increased IMT values have higher recurrence of cerebral infarction.
