120例缺血性脑卒中患者DSA检查结果分析

摘要

目的 探讨缺血性脑卒中患者数字减影全脑血管造影(DSA)的特征,评价DSA在缺血性脑卒中诊治中的价值.方法 分析120例确诊为缺血性脑卒中患者的DSA资料,包括脑供血动脉狭窄或闭塞发生率,血管狭窄部位、程度,责任动脉检出率及NIHSS评分与脑供血动脉狭窄的关系等.结果 120例缺血性脑卒中患者脑供血动脉狭窄或闭塞的发生率为73.33%,责任动脉的检出率为77.27%;血管狭窄或闭塞的好发部位依次为颈内动脉起始部(18.18%)、大脑中动脉水平段(14.97%)、椎动脉开口处(12.30%).狭窄组患者NIHSS评分高于非狭窄组,差异存在统计学意义(P＜0.05).结论 缺血性脑卒中患者应尽早行DSA检查明确有无颅内外脑供血动脉狭窄,对二级预防方案的选择起着重要的作用,如药物治疗、支架置入术等.%Objective To explore the characteristics of DSA in patients with ischemic stroke, and to evaluate the value of DSA in the diagnosis and treatment on ischemic stroke. Methods DSA data including rate of cerebral artery stenosis or occlusion of the incidence, the position and degree of stenosis, detection rate of responsibilities arterial and NIHSS score and brain feeding arteries narrow relationship in 120 patients with ischemic stroke were analyzed. Results The rate of cerebral artery stenosis or occlusion in 120 patients was 73. 33% while it was 77. 27% in target artery. The predilection sites of cerebral vascular stenosis or occlusion were the internal carotid artery( 18. 18% ), horizontal segment of middle cerebral artery ( 14. 97% ) and vertebral artery openings( 12. 30% ). The mean NIHSS score in the stenosis group was significantly higher than that in the non - stenosis group ( P <0. 05 ). Concluosion The patients with ischemic stroke should be performed DSA to clarify whether intracranial/extracranial cerebral artery stenosis exist.
