Correlation of acute ischemic cerebral infarction with carotid atherosclerosis plaque

Yun Xu

Abstract

Objective:Atherosclerosis of the carotid artery is the main cause and risk factor of ischemic cerebral infarction.We aim to evaluate the relation between acute ischemic cerebral infarction and the carotid atherosclerosis plaque.Methods: The distribution,shape,number and echoic features of the carotid atherosclerosis plaques confirmed by MRI diffusion-weighted imaging(DWI) were analyzed by color Doppler ultrasonography in 90 patients with acute ischemic cerebral infarction(Group A) and 82 controls(Group B).Results: The positive rate of acute cerebral ischemic infarction was significantly higher in Group A(76.7%) than in Group B(32.9%,P 0.01).And the plaque in Group A was mainly characterized by irregularity(36.8%) and heterogeneity(61.1%,P 0.01).Conclusion: Ischemic cerebral infarction is strongly correlated with the nature of the carotid atherosclerosis plaque.
