Abstract：
Objective To evaluate the clinical value of the color Doppler ultrasound for cerebral infarction in patients with extracranial carotid artery and vertebral artery. Methods Ninty-one cases of cerebral infarction patients in the hospital were examined of extracranial internal carotid artery, vertebral artery by color Doppler ultrasound. The pathological change patterns of arterial wall and the inner diameter of the arterial lumens and the peak flow rate (PSV), resistent index (RI)of the vertebral artery were observed.Results In the 91 cases of cerebral infarction patients, the inner diameter of carotid artery beyond the normal range, there were 17 cases in the left, 22 cases in the right.The most plaqueslie in carotid artery.The type of plaques was flat applanation spot at most, following was hard spot.Vertebral artery's peak flow rate was usually reduce, 52 cases in left, 57 cases in right. 22 patients' resistent index beyond the normal range in the left, and 36 cases in right.Conclusions The color Doppler ultrasound to extracranial carotid artery and vertebral artery provides the morphology and hemodynamics's change, offers important messages for the clinical diagnosis and treatment in the cerebral infarction.
