Title: A Study of Color Doppler Flow Imaging of Intracranial Arteries and Carotid Arteries in Patients with Stroke
Abstract: Objective To study the morphology,structure and hemodynamics of intracranial arteries and carotid arteries with color Doppler flow imaging in patients with stroke. Methods A noninvasive method based on color Doppler ultrasound was used for quantification of intima-media thickness,identification of plaque and determination of hemodynamics in intracranial arteries and carotid arteries.155 patients with stroke and 80 healthy subjects were imaged. Results (1) Intima-media thickness of common carotid arteries(CCA) in all type stroke patients were more thicker than that in healthy subjects.There were 109 patients with plaques in the bifurcation of the carotid artery.(2) Time average velocities of internal carotid artery(TAV ICA ) were significantly reduced in all type stroke patients than normal subjects.The resistance index(RI) and pulsatility index(PI) in stroke patient were higher than that in normal subjects.(3) Time average velocity of middle cerebral artery(TAV MCA ) was lower in cerebral infarction than normal subjects,TAV MCA was higher in cerebral hemorrhage than that in normal subjects,There were higher and lower TAV MCA in complex stroke. Conclusions The more severe atherosclerosis in all type stroke patients and high frequent appearance of plaques in carotid arteries were associated with the incidence of stroke.The study of color Doppler flow imaging of cerebral flow and carotid artery will help us predicting different type strokes,detecting the effects of treatment and reducing the recurrent stroke.
