Abstract:
Objective:To explore the application of carotid ultrasonography in detecting carotid artery lesions of patients with ischemic cerebrovascular disease(ICVD).Methods:Carotid ultrasonography and vascular reactivity(VR)were performed on 82 patients with ICVD and 40 health controls with Color Doppler Ultrasound.The ultrasonic indexes were statistically analyzed. The intima-media thickness(IMT)and the plaque score,the plaque total area and the cerebral blood flow volume of two groups were compared with each other.Results:Vessel diameter (VD),IMT,peak systolic velocity (PSV),end-diastolic velocity (EDV),mean flow velocity(MFV)in patients with severe stenosis of internal carotid artery and common carotid artery in ICVD group were significantly higher than those in control group,and the differences were statistically significant(P <0.01).VR in patients without stenosis and with mild,moderate and severe stenosis was lower than that in the control group(P <0.05).In ICVD group,IMT,carotid plaque score and plaque total area were significantly higher than those in the control group(P <0.01).Conclusions:The detection on degree of carotid lesions in patients with ICVD via carotid ultrasonography was conducive to understanding the status of ICVD,so as to determine the course and the prognosis.It was significant to clinical treatment of ICVD.
