短暂性脑缺血与脑动脉狭窄之间关系的研究

Study on relationship between transient cerebral ischemia and cerebral artery stenosis

目的:观察短暂性脑缺血发作患者脑动脉狭窄情况,分析两者之间关系。方法:回顾性分析60例短暂性脑缺血发作患者全脑血管造影结果,明确患者有无脑动脉狭窄以及脑动脉狭窄程度,分析患者脑动脉狭窄程度和脑血管疾病的相关性。结果:本院60例短暂性脑缺血发作患者中,有56例存在不同程度的脑动脉狭窄(93.33%);资料分析结果显示,短暂性脑缺血发作患者脑动脉狭窄出现的概率极高,且随着脑血管受累越多,短暂性脑缺血发作的概率不断增加。结论:脑动脉狭窄患者极易出现短暂性脑缺血发作,且伴随累及多条脑血管。在临床诊断治疗过程中合理应用全脑血管造影进行检查分析,找出脑动脉狭窄,给予有效治疗,能够极好的避免缺血性卒中。

Objective To observe the cerebral artery stenosis conditions of patients with transient ischemic attack and to analyze the relationship between them. Methods： The aortocranial angiography results of 60 cases of transient ischemic attack were retrospectively analyzed to determine whether the cerebral arterial stenosis occurred or not, and its degree was analyzed. Then, the relationship between cerebral artery stenosis and transient ischemic attack was analyzed. Results： Among the 60 case, there were 56 cases（93. 33%） with different degrees of cerebral arterial stenosis. The data analysis showed that transient ischemic attack patients had anextremely highprobability of cerebral arterial stenosis, and the probability increased with the increase of the involved cerebral vessels.Conclusions： The transient ischemic attack patients are prone to cerebral artery stenosis, and have multiple involved cerebral vessels.Therefore, it should rationally use the aortocranial angiography for examination and analysis to find the cerebral artery stenosis, whichis then treated effectively to avoid ischemic attack.
