Abstract：Objective To analyze the influence of internal carotid artery extra-cranial stenosis on blood supply to the brain with application of combination of Doppler ultrasonography and trans-cranial Doppler ultrasonography. Methods Altogether 85 patients with unilateral carotid artery stenosis who had been confirmed by color Doppler ultrasound from January 2012 to July 2014 were selected, among whom the light and moderate stenosis were found in 35 cases and taken as Light and Moderate Stenosis Group; severe stenosis and occlusion were revealed in 50 cases and taken as Severe Stenosis and Occlusion Group. Moreover, 50 healthy people with normal vascular bilateral intracranial and extra-cranial carotid artery were selected as Control Group. Then, the blood spectrum morphology, blood flow velocity, pulsatility index and collateral circulation were observed. Results The blood flow velocity and pulsatility index in Severe Stenosis and Occlusion Group were lower than those of Control Group with statistically significant differences (P<0.05). While, Light and Moderate Stenosis Group showed higher blood flow velocity and pulsatility index than Severe Stenosis and Occlusion Group as well as Control Group with statistically significant differences (P<0.05). Among all the patients with severe stenosis and occlusion, the establishment of 3 collateral circulations was seen in 3 cases; the establishment of 2 in 14 cases, the establishment of 1 in 13 cases. Conclusion The combination of Doppler ultrasonography and transcranial Doppler carotid artery stenosis could be used for assessment of intracranial hemodynamics changes and collateral circulation establishment caused by carotid artery stenosis, which was helpful for immediate intervention and prevention of ischemic stroke.
