短暂性脑缺血发作DSA检查的临床分析

Clinical Analysis of DSA Examination in Patients with Transient Ischemic Attack

目的:通过数字减影血管造影(DSA),研究短暂性脑缺血发作(TIA)与供血脑动脉病变的关系,探讨TIA发病机制。方法:选择TIA患者30例行DSA全脑血管造影,观察患者颈总动脉,颈内动脉和椎-基底动脉颅内、外段血管有无粥样硬化斑块、性质及狭窄程度。结果:行DSA检查60例中48例(80%)有粥样硬化斑块,其中重度狭窄即狭窄程度≥50%的有30例(50%)。结论:DSA检查在诊断TIA有重要的临床价值,从而可以明确TIA患者血管粥样硬化斑块的性质、狭窄程度,对指导有效治疗起着重要作用。

Objective：By digital subtraction angiography （DSA）, study of transient ischemic attack （TIA） and the blood supply to the brain arterial disease, and to explore the pathogenesis of TIA. Methods：Select TIA patients with 60 routine cerebral angiography DSA were observed in patients with carotid artery, internal carotid artery and vertcbral-basilar artery intracranial and external segmental vessels whether the atherosclerofic plaque, nature and degree of stenosis.Results：During DSA, 60 cases, 48 cases （80%） of atherosclerotic plaque, in which severe stenosis or ≥ 50% stenosis were 15 cases （50%）.Conclusion：DSA examination in the diagnosis of TIA has important clinical value, which can be clearly TIA in patients with atherosclerotic plaques in blood vessels of the nature, degree of stenosis, the guide plays an important role in effective treatment.
