Value of High Frequency Ultrasound in the Diagnosis of Carotid Artery Hemodynamic Changes and Structure in Diabetes Mellitus Patients
Objective To study the diagnostic value of high frequency ultrasound in the changes of carotid hemodynamics and structure in diabetes mellitus patients.Methods A total of 75 diabetes mellitus patients diagnosed and treated in our hospital from January 2022 to June 2023 were selected as the study group,and 75 healthy people who underwent physical examination in our hospital during the same period were selected as the control group.Both groups were examined by high frequency ultrasound.The peak systolic velocity(PSV),end-diastolic velocity(EDV),vascular resistance index(RI),carotid intima-media thickness(IMT),and number of plaques were compared between the two groups.The efficacy of different indicators of high frequency ultrasound in the diagnosis of diabetic carotid atherosclerotic plaques was analyzed.Results PSV and EDV in the study group were lower than those in the control group,and RI was higher than that in the control group(P＜0.05).The IMT of common carotid artery,bifurcation of carotid artery and left and right internal carotid artery in the study group were higher than those in the control group(P＜0.05).The plaque detection rate of the study group(86.67％)was higher than that of the control group(53.33％),the total number of plaques in the study group was 165,and the total number of plaques in the control group was 44.The sensitivity and specificity of PSV+EDV+RI+IMT combined diagnosis of diabetic carotid atherosclerotic plaque were higher than those of single detection of each index(P＜0.05).Conclusion High frequency ultrasound has a high diagnostic value for carotid hemodynamic changes and structure in diabetic patients.It can judge carotid hemodynamics and plaque number.In particular,the combined application of each detection index can improve the diagnostic efficacy of diabetes mellitus with carotid atherosclerotic plaque,and provide a reliable basis for early clinical treatment and prevention.
