目的：通过数字减影全脑血管造影术（DSA）检查，研究短暂性脑缺血发作（TIA）和脑动脉病变的关系。方法对30例TIA患者的临床诊治进行回顾性研究分析，了解TIA行全脑血管造影患者颈总动脉、颈内动脉系统和椎-基底动脉颅内、外段血管有无粥样硬化斑块及性质、血管狭窄程度及其他病变。结果30例TIA患者中20例（66.7%）存在颅内-外动脉狭窄，其中7例（21.0%）为颈内动脉狭窄，4例（13.3%）为大脑中动脉狭窄，2例（6.7%）为大脑前动脉狭窄；2例（6.67%）颈内动脉并椎动脉狭窄，5例（16.7%）椎动脉狭窄；1例（3.3%）烟雾病；2例（6.7%）血管痉挛；7例（23.3%）血管造影阴性。应用支架治疗椎动脉、颈内动脉狭窄＞70%的患者，效果良好。结论DSA对短暂性脑缺血发作与脑动脉病变能准确的评估，对明确TIA的病因有重要的临床价值,对治疗具有指导意义。

Objective To study the relationship between transient ischemic attack (TIA) and lesion of blood-supply cerebral artery through examination of digital subtraction angiography (DSA). Methods The therapeutic data was studied and analyzed retrospectively in 30 patients with TIA, and incidence and nature of atherosclerotic plaques, severity of vascular stenosis and other lesions were observed in common carotid artery (CCA), internal carotid system and intracranial or extracranial vertebrobasilar artery. Results In 30 cases of TIA, 20 (66.7%) had intracranial or extracranial artery stenosis and among them, 7 (21.0%) had intracarotid stenosis, 4 (13.3%) had middle cerebral artery stenosis, 2 (6.7%) had anterior cerebral artery stenosis, 2 (6.67%) had stenosis of both intracarotid and vertebral arteries, 5 (16.7%) had vertebral artery stenosis, 1 (3.3%) had moyamoya disease, 2 (6.7%) had vasospasm, and 7 (23.3%) had negative angiography outcomes. Stenting for treating vertebral artery stenosis or intracarotid stenosis had good curative effects in more than 70%patients. Conclusion DSA can accurately review TIA and lesion of blood-supply cerebral artery, which is important to clear the cause of TIA in clinic and has guiding significance to the treatment.
