摘　　要：目的分析基于CT血管造影(computed tomography angiography,CTA)评估的基底动脉弯曲对老年脑桥梗死远期预后的评估价值。方法回顾性分析2020年9月至2023年9月期间四川省广元市中医医院放射科收治的老年脑桥梗死患者98例临床资料,根据预后情况分为预后良好组61例和预后不良组37例。比较2组患者CTA评估的基底动脉弯曲参数,分析其与患者远期预后的相关性,并评估其预测患者预后的预测价值。结果预后不良组基底动脉直径明显低于预后良好组,基底动脉弯曲长度、弯曲指数明显高于预后良好组,差异有统计学意义(P<0.01)。基底动脉直径与老年脑桥梗死患者预后不良呈负相关(P<0.01),基底动脉弯曲长度、弯曲指数与老年脑桥梗死患者预后不良呈正相关(P<0.01)。基底动脉弯曲长度、弯曲指数是老年脑桥梗死患者预后不良的危险因素(P<0.01),基底动脉直径是老年脑桥梗死患者预后不良的保护因素(P<0.01)。ROC曲线分析显示,CTA评估的基底动脉弯曲参数联合预测老年脑桥梗死患者远期预后的曲线下面积为0.938(95%CI:0.870~0.977),敏感性为94.59%,特异性为75.41%。结论CTA可评估基底动脉弯曲程度,直观反应基底动脉形态学特点,为预测老年脑桥梗死患者远期预后提供影像学依据。Objective To analyze the evaluation value of basilar artery curvature based on computed tomography angiography for the long-term prognosis of elderly patients with pontine infarction.Methods A retrospective analysis was conducted on 98 elderly patients with pontine infarction 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 prognosis was assessed.Results The poor prognosis group had significantly smaller diameter of basilar artery,longer length in basilar artery curvature,and larger curvature index than the good prognosis 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 basilar artery curvature in predicting the long-term prognosis of elderly patients with pontine infarction 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 curvature,intuitively reflect the morphological characteristics of basilar artery,and provide imaging basis for predicting the long-term prognosis of elderly patients with pontine inf
