Abstract
Objective To investigate the relationship between the degree of carotid stenosis as well as the character of atherosclerotic plaque and cerebral infarction. Methods From April 2013 to January 2014, totally 100 acute cerebral infarction patients were studied as the observation group. Meanwhile, 100 cases who were not acute cerebral infarction were selected as the control group. Carotid artery of all were examined by carotid artery CTA to observe the degree of carotid stenosis and to judge plaque characters as well as their location. Then they were measured by plaque analysis software. Results The number of no stenosis, mild and severe stenosis and occlusion in observation group was higher than those in control group(25.2%, 28.0%, 15.5%, 11.1% vs 54.0%, 15.2%, 6.8%, 3.0%, respectively)(P 0.05);compared with control group, plaque detection rate was high(74.8% vs 46.0%)(P 0.01); in observation group, the occurrence of unstable plaque was higher than stable plaque(83.9% vs 38.0%)(P 0.05), in control group, the occurrence of stable plaque was higher than unstable plaque(62.0% vs 16.1%)(P 0.05); the incidence of mixed plaques and soft plaques in observation group was significantly higher than those of control group(P 0.01), the incidence of fibrous plaques and calcified plaques in control group was significantly higher than those of observation group(P 0.01). Conclusion The degree of carotid stenosis as well as the characters of atherosclerotic plaques are associated with acute cerebral infarction and there is no correlation between atherosclerotic plaques location and acute cerebral infarction
