Association between Carotid Atherosclerotic Plaques and Cerebral Infarction and the Ultrasonic Imaging Features of the Former as Manifested by Color Doppler Ultrasonography
摘要
Abstract
Objective: To analyze the ultrasonic imaging features of carotid atherosclerotic plaques in cerebral infarction patients and investigate the application values of color doppler ultrasonography in preven-tion and treatment of cerebral infarction.Method: 100 cerebral infarction patients (observation group) and another 100 healthy people ( control group) were selected, and the results of color doppler ultrasonography on the carotid arteries of the two groups were analyzed. Result: Of the observation group, total 189 carotid artery plaques were observed in 93 patients ( 93. 00%); while of the control group, total 28 carotid artery plaques were observed in 16 people (16.00%); and the difference was statistically significant (P<0.05), but the patchiness conditions of the two groups were similar and the difference was statistically insignificant (P>0.05). In the patients of the observation group, most (44.44%) were soft plaques, while in the people of the control group, most (57.14) were hard plaques, and the difference was statistically significant (P<0. 05) . The patients of the observation group had larger common carotid artery intima -media thickness ( CCA-IMT) and bifurcation intima - media thickness ( BIF-IMT) than the control group, and the differences were both statistically significant ( P<0.05) . The patients of the observation group had lower systolic peak ve-locity ( SPV) and end diastolic velocity ( EDV) of the common carotid arteries, but higher resistance index ( RI) of the common carotid arteries than the control group, and the differences as statistically significant ( P<0. 05 ) . Conclusion: Cerebral infarction patients had significantly increased number of carotid artery plaques, which are mainly soft, increased CCA-IMT and decreased blood flow velocity. Color doppler ultra-sonography can discover carotid atherosclerotic plaques and determine the nature as early as possible, and consequently provide important information for the prevention and treatment of cerebral infarction.关键词
