Abstract:
Objective To investigate the characteristics and risk factors of the cerebral artery atherosclerotic stenosis in patients aged 90 years and older. Methods A total of 92 patients,aged 90 years or older,admitted to our hospital from July 2009 to July 2014 were respec-tively enrolled in this study. All participants underwent CTA to assess the presence and severity of atherosclerotic stenosis with intracranial and extracranial cerebral artery. The association between atherosclerotic stenosis and related risk factors were analyzed. Results The preva-lence of cerebral artery atherosclerotic stenosis was high in the cohort. The frequency of stenosis with intracranial artery was higher than the frequency with extracranial artery (86. 2% vs 44. 8%). The most common positions of cerebral artery atherosclerotic stenosis were the middle cerebral artery (43. 1%),the posterior cerebral artery (43. 1%),and extracranial vertebral artery (32. 8%). The mean age,body mass in-dex,systolic and diastolic blood pressure,and fasting blood glucose of stenosis group are significantly different from the non-stenosis group in single factor analysis (P<0. 05). Multivariate Logistic regression analysis showed body mass index was the independent risk factor of cere-bral artery atherosclerotic stenosis(β=1. 326,OR=3. 765,P<0. 05). Conclusion The prevalence of cerebral artery atherosclerotic steno-sis was high in the patients aged 90 years and older. Body mass index was the independent risk factor. The weight control should be pay atten-tion to prevent cerebral artery atherosclerotic stenosis and stroke.
