脑梗死急性期伴认知障碍患者DSA影像学特征分析

目的 探讨脑梗死急性期伴认知障碍患者DSA影像学特征。方法 选择2016年1月-2017年12月江门市人民医院神经内科住院的脑梗死急性期患者,根据脑梗死急性期蒙特利尔认知评分情况不同分为研究组(97例)、对照组(128例); 收集所有患者性别、年龄、实验室检查及全脑血管造影资料,分析脑梗死急性期伴认知障碍患者DSA影像学表现(颅内外动脉硬化、闭塞、狭窄及侧支循环情况)。结果 研究组患者关键部位脑梗死、分水岭梗死、腔隙性脑梗死及合并脑白质高信号患者更为多见,其MCA、ICA狭窄比例明显高于对照组(P<0.05); 研究组患者侧支循环不良比例明显低于对照组(P<0.05)。结论 脑梗死急性期伴认知功能障碍患者以关键部位脑梗死、分水岭梗死、腔隙性脑梗死及合并脑白质高信号患者更为多见,其脑动脉狭窄率较无认知障碍患者明显升高。

The analysis of DSA imaging features in patients with acute cerebral infarction accompanied by cognitive impairment

ObjectiveTo analyze DSA imaging features in patients with acute cerebral infarction accompanied by cognitive impairment.Methods Of the patients with acute cerebral infarction in neurology department of Jiangmen people's Hospital from January 2016 to December 2017, 225 cases were enrolled into our studies and were divided into the study group(97 cases)and the control group(128 cases)according to their Montreal cognitive scores. For each case, gender, age, laboratory parameters and angiographic data were documented according to their case histories,the DSA manifestations were analyzed(intracranial and extracranial arteriosclerosis, occlusion, stenosis and collateral circulation).Results The critical site infarction, watershed infarction, lacunar infarction with hyperintense white matter were more common in the study group than those in the control group and the proportion of patients with MCA, ICA stenosis in the study group was significantly higher than that in the control group(P<0.05). The proportion of patients with poor collateral circulation in the study group was significantly lower than that in the control group(P<0.05).Conclusion The critical site infarction, watershed infarction, lacunar infarction with hyperintense white matter were more common in patients with acute cerebral infarction accompanied by cognitive impairment, and the rate of stenosis of the cerebral arteries was significantly higher than that of the patients without cognitive impairment.
