Abstract:
Objective To analyze the evaluation value of basilar artery curvature based on compu-ted tomography angiography for the long-term prognosis of elderly patients with pontine infarc-tion.Methods A retrospective analysis was conducted on 98 elderly patients with pontine infarc-tion admitted in Guangyuan Hospital of Traditional Chinese Medicine from September 2020 to September 2023.According to the prognosis status,they were divided into good prognosis group(n=61)and poor prognosis group(n=37).The computed tomography angiography parameters of basilar artery curvature were compared between the two groups to analyze the correlation with long-term prognosis of patients.The predictive values of these parameters in predicting the prog-nosis was assessed.Results The poor prognosis group had significantly smaller diameter of basi-lar artery,longer length in basilar artery curvature,and larger curvature index than the good prog-nosis group(P＜0.01).The diameter of basilar artery was negatively correlated,and the length in basilar artery curvature and the curvature index were positively correlated with poor prognosis in the elderly patients with pontine infarction(P＜0.01).The length of the basilar artery curvature and the curvature index were risk factors for poor prognosis in elderly patients with pontine infarction(P＜0.01).The diameter of the basilar artery was a protective factor for poor prognosis in elderly patients with pontine infarction(P＜0.01).ROC curve analysis indicated that the area under curve value of combined above three computed tomography angiography parameters of bas-ilar artery curvature in predicting the long-term prognosis of elderly patients with pontine infarc-tion was 0.938(95％CI:0.870～0.977),with a sensitivity of 94.59％and a specificity of 75.41％.Conclusion computed tomography angiography can evaluate the degree of basilar artery curva-ture,intuitively reflect the morphological characteristics of basilar artery,and provide imaging ba-sis for predicting the long-term prognosis of elderly patients with pontine infarction.
