短暂性脑缺血发作DSA 32例临床报告

目的:应用脑血管造影技术(DSA)对短暂性脑缺血发作(Transient ischemic attack,TIA)进行病因研究。方法:选择住院的TIA患者32例进行脑血管造影,12例进行了溶栓治疗,30例病人行颈动脉超声,观察TIA患者DSA结果,并与颈动脉超声结果比较。结果:1.TIA患者DSA显示颅内、外动脉异常,总异常率为93%(30/32);2.DSA显示颈内动脉颅外段异常78.1%(25/32),与颈动脉超声结果86.7%(28/30)较一致。结论:颅内外血管狭窄或闭塞可能是TIA的主要原因,对于TIA患者及早行DSA和颈动脉超声,进一步行介入及溶栓治疗,从而避免或减少脑血栓的发生。

The clinical report of 32 cases Transient ischemic attack DSA

Objective To study the etiopathogy of transient ischemic attack(TIA) using the method of digital subtraction angiography(DSA). Methods:32 TIA patients were performed DSA, 30 patients carotid ultrasonography, 12 patients intra-arterial thrombolytic therapy. To contrast the patients' results of DSA with the results of carotid ultrasonography. Results: 1、 the total abnormal rate of intracranial artery and extracranial artery of DSA is 93%(30/32);2 the total abnormal tate of extracranial internal carotid artery of DSA is 78.1%(25/32); carotid ultrasonography 86.7%(28/30),respectively with no statistical difference. Conclusion: The occlusion or stenosis in extra-and intracranial arteries may be the main cause of TIA.It is improtant for the TIA patients to perform DSA 、 carotid ultrasonography 、 interverntional therapy intra-arterial thrombolytic therapy. It can avoid or decrease the onset and development of acute cerebral infarction.
