ABSTRACT
Objective To investigate the ultrasonic performance of carotid atherosclerotic plaque and the correlation between microvessel density in plaque .Methods 87 cases of patients undergoing carotid artery plaque dissection were selected .113 plaques were found .All patients were taken carotid color Doppler sonography test and analysis of the plaque .The maximum thickness of plaques was taken HE stained ,and the vessel density in the plaque was counted .The correlation with sonographic performance of plaques was analyzed .Results The maximum plaque thicknesses in hard plaque ,soft plaque and mixed plaque were (0.49 ±0.05)mm,(0.36 ±0.08)mm and (0.39 ± 0.10)mm,respectively,and cross-sectional area stenosis rates were (88.32 ±6.51)%,(68.92 ±12.05)% and (71.95 ±13.04)%,respectively,the differences were statistically significant (F=16.329,23.723,all Pmixed plaques>hard plaque,the differences were statistically significant (t=6.579 and 9.392,all P<0.05).Pearson cor-relation analysis showed that the maximum plaque thickness and cross -sectional area stenosis rate in soft plaque were positive correlation between microvascular density values (r=0.372,P=0.011;r=0.438,P=0.000).Conclusion Color Doppler ultrasound examination might indirectly reflect microvessel densities in carotid artery plaque .It could be used preliminary assessment of vulnerability of carotid artery plaque .
