Diagnostic value of high-frequency ultrasound in detecting carotid atherosclerosis in patients of type 2 diabetes

[Objective] To evaluate the diagnostic value of high-frequency ultrasound in detecting carotid atherosclerosis in patients of type 2 diabetes.[Methods] One hundred patients of T2DM and thirty healthy subjects were examined by high-frequency ultrasound.The intimal-medial thickness(IMT) and the atheroslerotic plaques of carotid artery were observed.[Results] There was a significant difference between C group and the other groups in IMT of carotid arteries,the plaque scores and the detection rate of plaques(P0.05).So was it between A and B groups with D group.There was a significant difference between C group and the other groups in the number of abnormal vessels and vessels with multiple-plaques detection(P0.05).The detection rate of soft plaque was higher than hard plague and mixed plaques(P0.05).There was no difference of rate of different plaques among the four groups(P0.05).[Conclusions] IMT and the carotid atheroslerotic plaques in the patients of type 2 diabetes are significantly increased with the course of diseases closely.The high-frequency ultrasound is a convenient,effective and valuable method to detect the carotid atherosclerosis of patients of type 2 diabetes.
