短暂性脑缺血发作与狭窄脑动脉供血关系

目的通过数字减影血管造影检查，探讨短暂性脑缺血发作（TIA）的临床特点及其与脑供血动脉狭窄的相关性。方法采用数字减影血管造影（DSA）对43例TIA患者进行全脑血管造影检查，观察患者颈总动脉，颈内动脉和椎基底动脉颅内颅外段血管有无粥样硬化斑快、性质及狭窄程度。结果43例中有动脉硬化斑块存在的31例，血管狭窄27例，血管迂曲3例，单侧颈内动脉颅内或颅外段闭塞4例，双侧颈内动脉末端闭塞1例一烟雾病。1例伴有梭形动脉瘤。颅内动脉狭窄16例，颅外动脉狭窄11例，至少存在2处血管狭窄14例，其中8例行血管内支架成型术治疗。结论DSA可明确TIA患者是否存在血管狭窄及严重程度，脑供血动狭窄可能是TIA的主要原因。

The relationship between transient ischemic attack and the feeding of the cerebral vascular stenosis

Objective To explore the relationship between transient ischemic attack （TIA） and the feeding of the cerebral vascular pathology with DSA. Methods 43 patients with TIA were detected with digital subtraction angiography to show the state of carotid artery （CCA）, internal carotid artery （ICA）, intra/extra part of vertebrabasilar artery. Results Of 43 patients, there were 31, 27 and 3 cases with atherosclersis plaque, artery stenosis and artery tortusity, respectively. There were 4 cases with unilateral occultation in intracranial part and extracranial part of ICA, 1 case with bilateral ICA occultation （Moyamoya disease） and 1 case with fusiform aneurysm. There were 16 with intracranial artery stenosis, 11 cases with extracranial artery stenosis and 14 cases with more than two lesions. Conclusion DSA can demonstrate the condition of the brain artery.
