老年脑梗死患者急性期全脑血管造影及脑动脉狭窄的危险因素分析

目的:探究老年脑梗死患者急性期全脑血管造影(DSA)及脑动脉狭窄的危险因素。方法:选择2010年1月~2016年9月期间我院收治的562例老年脑卒中患者为研究对象。经DSA造影观察脑血管动脉造影脉狭窄情况,并收集患者一般资料,采用单因素分析及多因素logistics回归分析脑动脉狭窄的危险因素。结果:562例脑卒中患者经DSA检查共发现469例患者出现脑动脉狭窄,中度狭窄301例,血管重度狭窄168例;颅内段发生率显著高于颅外段(P0.05);高龄(OR=1.434,P0.05)、高血压(OR=2.084,P0.05)、糖尿病(OR=2.235,P0.05)及吸烟(OR=2.734,P0.05)是老年脑卒中患者脑血管狭窄的危险因素。结论:DSA显示老年人脑卒中患者多存在脑血管动脉狭窄的发生,年龄、高血压、糖尿病及吸烟是老年脑卒中患者脑血管狭窄的危险因素。

Analysis of Risk Factors of Acute Digital Subtraction Angiography and Cerebral Artery Stenosis in Elderly Patients with Cerebral Infarction

ABSTRACT Objective: To explore the risk factors of acute digital subtraction angiography (DSA) and cerebral artery stenosis in el- derly patients with cerebral infarction. Methods: 562 cases of elderly patients with stroke in our hospital during the period of January 2010 to September 2016 were selected. DSA angiography was used to identify cerebral vascular stenosis. The characteristics were col- lected, Univariate analysis and multivariate logistics regression analysis were adopted for analysis of risk factors of cerebral artery steno- sis. Results: 469 patients with cerebral artery stenosis were found in 562 stroke patients by DSA, 301 cases of moderate stenosis and 168 cases of intracranial vascular severe stenosis were examined; Cerebral artery stenosis incidence rate in intracranial was significantly high- er than that of extracranial (P<0.05); Age (OR=1.434, P<0.05), hypertension (OR=2.084, P<0.05), diabetes (OR=2.235, P<0.05) and smoking (OR=2.734, P<0.05) were risk factors for senile cerebral stroke patients with vascular stenosis factors. Conclusion: DSA shows that there is a high incidence of cerebral vascular stenosis in elderly patients with cerebral stroke.Age,hypertension, diabetes mellitus and smoking are the risk factors of cerebral vascular stenosis in elderly patients with stroke.
