Correlation analysis on risk factors in 30 cases of intracranial vascular stenosis artery aneurysm / 重庆医学

ABSTRACT

Objective To analyze the imageological characteristics of intracranial vascular multiple stenosis aneurysms and to e-valuate the influence of cerebral vascular stenosis caused hemodynamic change on the aneurysm occurrence .Methods The clinical data of 30 inpatients with intracranial arterial multiple stenosis aneurysms diagnosed by CTA and DSA ,who were hospitalized due to ischemic cerebrovascular disease in the neurology department of 251 Hospital of Beijing Military Region from January 2007 to May 2012 ,were retrospectively analyzed and taken as the observation group ;contemporaneous 30 cases of aneurysm without in-tracranial and extracranial arterial stenosis admitted to the neurosurgery department were taken as the control group .The gender , age of onset ,number of aneurysms ,whether or not complicating hypertension ,diabetes ,smoking ,hyperlipemia ,plaque of extracrani-al carotid artery ,ischemic stroke and cerebral arterial abnormal development were compared between the two groups .The Logistic single factor and multi-factor correlation analysis was adopted to evaluate the correlation between the aneurysm occurrence with the hemodynamic changes caused by atherosclerotic stenosis .Results Cystic multiple aneurysms were common in the observation group ,which was up to 4 in number ,the age was more than 60 years ,the majority was complicated by hypertension ,diabetes ,hyper-lipemia ,cerebral stroke ,plaque of extracranial carotid artery and intracranial arterial multiple stenosis were common .Aneurysms mostly occurred in intracranial artery with severe stenosis .The gender differences were unobvious .The control group was domina-ted by young patients .Single aneurysm was more common without intracranial artery multiple stenosis .The occurrence rate of ca-rotid arterial plaque and cerebral stroke was lower .The partial patients had smoking ,hyperlipidemia and hypertension .The Logistic regression analysis between the two groups showed that ischemic stroke ,cerebral arterial development abnormality and atheroscle-rosis plaque of extracranial carotid artery had significant correlation .Conclusion The aneurysm occurrence is related with cerebral arterial atherosclerotic stenosis ,which becomes the important factor leading to aneurysm formation and should arouse attention to conduct early diagnosis and early treatment .
