Objective To investigate the clinical and imaging features of carotid web(Caw)patients with asymptomat-ic,transient ischemic attack(TIA),ipsilateral acute ischemic stroke(AIS).Methods Patients diagnosed with carotid webs by CT angiography(CTA),which were retrospectively selected and divided into three groups(asymptomatic Caw group,TIA Caw group and ipsilateral AIS Caw group),according to the occurrence of acute ischemic change.Results A total of 76 Caw patients were diagnosed,including 26 asymptomatic Caw,22 TIA Caw,19 AIS Caw and 9 other cerebrovas-cular disease.There were 59 males and 17 females.There was a statistical significance in hypertension,smoking and high-density lipoprotein levels(asymptomatic Caw vs.TIA,asymptomatic Caw vs.AIS,P＜0.05).There was a statistical sig-nificance in diabetes(TIA vs.asymptomatic Caw,TIA vs.AIS,P＜0.05).In the comparison of three groups of carotid webs image features including axial length,oblique sagittal length,angle and stenosis,only stenosis had statistical signifi-cance(asymptomatic Caw vs.AIS,P＜0.05).Age,sex,systolic blood pressure,diastolic blood pressure,total cholesterol level,triglyceride level,low density lipoprotein level,carotid webs(axial length,oblique sagittal length,angle)had no statis-tical significance(P＞0.05).Conclusion Carotid web is more common in males.Carotid web patients with associated risk factors such as hypertension,diabetes,smoking and high-density lipoprotein levels may be more liable to the occurrence of TIA and AIS.Carotid stenosis caused by carotid webs,which is also closely related to AIS.
