摘要
目的探讨短暂性脑缺血发作(TIA)全脑血管造影的临床意义。方法选择120例TIA患者行全脑血管造影检查,比较脑动脉颅内段、颅外段病变分布情况。结果 120例患者全脑血管造影检查阴性13例(10.83%),动脉硬化性改变24例(20%),血管狭窄或闭塞78例(65%),非动脉硬化性改变5例(4.17%),其中烟雾病3例,动脉夹层2例。颈内动脉系统的TIA以颅内段血管狭窄或闭塞为主,椎-基底动脉系统的TIA以颅外段血管狭窄或闭塞为主。结论颅内段血管狭窄是颈内动脉系统TIA的主要病因,颅外段血管狭窄是椎-基底动脉系统TIA的主要病因,建议TIA患者早期行脑血管造影检查,指导临床治疗。
Objective To investigate the clinical significance of the cerebral angiography in patients with transient ischemic attack (TIA). Methods 120 patients with TIA underwent cerebral angiography were selected, lesions distribution of cerebral artery in intracranial and extracranial was compared. Results Among 120 cases there were 13 patients with negative cerebral angiography (10. 83% ), 24 patients with arteriosclerotic changes (20%), 78 patients with vascular stenosis or occlusion (65%), 5 patients with non atherosclerotic changes (4.17%) including 3 cases of moyamoya disease and 2 cases of aortic dissection. Internal carotid artery TIA in intracranial vascular stenosis or occlusion, vertebral basilar artery system TIA with extracranial vascular stenosis or occlusion. Conclusion Intracranial vascular stenosis is the major cause of TIA in internal carotid artery system, while extracranial vascular stenosis is the major cause of TIA in vertebral basilar artery system, it suggested that patients with TIA should take cerebral angiography early, to guide the clinical therapy.
