Objective To explore the value of color Doppler ultrasound for detections of carotid intima-media thickness, plaque and carotid stenosis in diagnosis of ischemic stroke.
Methods Totally 458 patients with carotid artery ultrasonography were selected and divided into control group (n=168, non-stroke health controls) and stroke group (n=290, ischemic stroke patients). The incidence rates of carotid artery intima-media thickness, plaque and different degrees of stenosis were analyzed in both groups.
Results There were significant differences in incidence rates of carotid intima-media thickness (IMT) thickening and carotid plaque between stroke group and control group (P < 0.05), and the degree of carotid stenosis in stroke group was significantly higher than that in control group (P < 0.05).
Conclusion Carotid intima-media thickness, plaque and stenosis degree are closely related with ischemic stroke. Carotid ultrasound can effectively increase the detection rate of stroke.
