Clinical value of color Doppler ultrasound detection of blood flow parameters and vascular diameter in carot-id artery and vertebral artery

Objective To investigate the effect and clinical value of color Doppler ultrasound detection of blood flow parameters and vascular diameter in carotid artery and vertebral artery.Methods 150 healthcases were collected as the study objects.According to the age and gender differences, making a detailed classification, color Doppler ultrasound was used to detected the internal carotid artery, vertebral artery and the carotid artery.Results As age grows,the blood flow velocity decreases,and the pulsatility index（ PI） and resistance index（ RI） has no obvi-ous relation with age;There were positive correlation between the diameter of the carotid artery and vertebral artery and age（ P〈0.05） ,and the male population the diameter of the carotid artery was significantly wider than that of the female population（P〈0.05）,left vertebral artery diameter was significantly wider than that of the right side（P〈0.05）.Conclusion Color Doppler ultrasound detection can let us get detailed carotid and vertebral artery anatomy and blood supply of information,which is good to diagnosis cerebrovascular disease.
