Cerebral infarction patients with carotid atherosclerotic plaque morphology changes,degree of stenosis of ultrasound performance char-acteristics and the value of ultrasonic diagnosis analysis
Objective To analyze cerebral infarction patients with carotid atherosclerotic plaque morphology changes,degree of stenosis of ultrasonic characteristics and the value of ultrasonic diagnosis.Methods Sixty cases of cerebral infarction patients treated in Chuzhou Hospital of Integrated Traditional Chinese and Western Medicine from July 2021 to December 2023 were retrospectively selected and included in the observa-tion group,60 cases of medical healthy subjects during the same period were selected and included in the control group.All entrants accept carotid ultrasound examination,carotid plaques detection and distribution properties,carotid stenosis,the types of plaque,plaque detection rate,carotid artery blood flow parameters[peak systolic velocity(PSV),peak diastolic velocity(EDV),resistance index(RI)]of the two groups were com-pared.The diagnostic efficacy of carotid artery blood flow parameters for cerebral infarction was analyzed using the receiver operating characteristic(ROC)curve.Results There was no statistically significant difference in the distribution of carotid atherosclerotic plaques between the two groups(P＞0.05).The proportion of soft spots in the observation group was 45.71％,which was higher than that in the control group(5.88％),and the proportion of hard spots was 25.71％,which was lower than that in the control group(58.82％),the differences were statistically signifi-cant(P＜0.05).The proportion of vulnerable plaques in the observation group was 65.71％,which was higher than that in the control group(11.76％),and the difference was statistically significant(P＜0.05).The detection rate of carotid artery stenosis in the observation group was 76.67％,which was higher than that in the control group(10.00％),and the difference was statistically significant(P＜0.05).The PSV and EDV in the observation group were(55.30±3.37)and(10.51±2.76)cm/s,respectively,which were lower than those in the control group[(60.12±4.28)and(15.91±3.53)cm/s],and RI in the observation group was 0.81±0.14,which was higher than that in the control group(0.73±0.11),the differences between the two groups were statistically significant(P＜0.05).The ROC curve analysis,carotid artery,PSV,EDV joint RI the sensitivity of the diagnosis of cerebral infarction was 89.76％,60.34％,AUC was 0.920,was greater than the single index of PSV(0.631),EDV(0.675),and RI(0.609)(P＜0.05).Conclusion Cerebral infarction patients with obvious morphological changes of carotid atherosclerotic plaques and narrow degree of change,through ultrasound the hemodynamic change obviously,implications for diagnosis of cerebral infarction.
