Relatioinship between ischemic cerebrovascular disease and atherosclerosis of the common carotid artery

Aim To study the relatioinship between ischemic cerebrovascular disease and atherosclerosis of the common carotid artery.Methods Color doppler ultrasonography of the carotid arteries was performed on 120 patients with ischemic cerebrovascular diseases.The maximum IMT of the posterial wall at distal common carotid artery and plaques in 120 patients were measured and compared with 100 controls without ischemic cerebrovascular diseases.Results IMT were significantly increased in ischemic cerebrovascular disease group compared with control subjects(P0.01).The rate of lesion detection was significantly different between two groups(P0.01).The most common site of plaque formation is the bulb of the common carotid artery(P0.05).There was no difference of occurrence rate between left and right(P0.05).Conclusion The severity of atherosclerosis of the carotid artery in ischemic cerebrovascular disease is higher than control group.Color doppler ultrasonography is an important technique in detecting atherosclerosis of the carotid artery in patients with ischemic cerebrovascular disease.
