Prediction Significance of Carotid Artery Color Ultrasound combine CTA in Evaluating the Risk of Cerebral Infarction
Objective To study the predictive value of carotid artery color ultrasound combined with CT angiography(CTA)in evaluating the risk of cerebral infarction,in order to provide reference for early clinical prediction and evaluation of the risk of cerebral infarction.Methods A total of 80 patients with cerebral infarction admitted to our hospital from January 2020 to December 2022(cerebral infarction group)and 80 non-cerebral infarction patients who required carotid ultrasound combined with CTA for medical reasons(control group)were selected as the research subjects.The results of carotid ultrasound combined with CTA were compared between the two groups,and the relevant factors affecting the occurrence of cerebral infarction were analyzed.The evaluation value of each individual result of carotid ultrasound combined with CTA for the risk of cerebral infarction was also analyzed.Results There were significant differences between the two groups in IMT,carotid plaque,soft plaque,mixed plaque,Crouse score,PSV,EDV,cerebrovascular stenosis degree and stenosis vessel distribution(P<0.05).IMT,carotid plaque properties,Crouse score,presence of carotid plaque,PSV,EDV,degree of cerebral vascular stenosis,and distribution of stenotic vessels are all associated with the occurrence of cerebral infarction(P<0.05).The importance of variables in descending order were carotid plaque nature,IMT,stenosis distribution,cerebrovascular stenosis degree,Crouse score,PSV,EDV,carotid plaque presence.The C-index of the histogram for the comprehensive assessment of the risk of cerebral infarction by carotid ultrasound combined with CTA was 0.925.The clinical efficacy of the histogram was evaluated by drawing DCA curve.Within the threshold of 0.05~1.0,the histogram showed positive clinical net benefit.Conclusion Carotid ultrasound combined with CTA can be used to evaluate the risk of cerebral infarction,and it can be used for early diagnosis and assessment in clinic,which can provide basis for predicting the risk of cerebral infarction and making targeted treatment plan,so as to improve the prognosis.
