摘　　要：目的 探讨局部脑血 流减少与血管因素间的相关关系和寻找TIA的有效诊断方法。方法对TIA病人进行SPECT%,TCD%、CCDS的检查,将其结果进行相关分析。结果 SPECT对TIA局部脑血流减少的诊断符合率为96.2％,颈内动脉系统TIA为96.6％ ;椎基底动脉系统TIA为95.7%。诊断符合率明显高于TCD和CCDS(50%)。结论 在TIA发作间期测定rCBF具有诊断价值,对TIA病人及时进行长期治疗是必要的。SPECT 对及时治疗TIA和防止局部脑组织不可逆性改变发生有重要的意义,可作为TIA的有效诊断方。TIA的血管因素主要为脑动脉硬化、颅内外血管的狭窄和颈动脉斑块数量及质量。Objective The TIA patients are of population in higher risk of stroke. It is importam to rapidly and accurately clarify the factors which causing TIA. TIA resulted from various factors, among which vascular diseases play an important role. In the clinic practice, the diagnosis of TIA is made only through the case history, since less physical signs seen in the interim.lt is thus crucial to diagnose TIA in a way based on objective basis. The purpose of this paper is to study the different methods to diagnose TIA and the relation of reduction of local brain blood with the blood vessels. Methods Fifty six cases of TIA in our hospital from 1998 to 1999 were examined by SPECT ,TCD and CCDS for rCBF, and a study on the relation of rCBF with blood vessels. Results The coincidence rate of SPECT examination and local blood reduction of TIA is 96.2%,which is higher than TCD and CCDS (50%). This coincidence is not influenced by age, sex, and so on. There is no difference between the elders and non-elders for the coincidence rate. The order of factors related to TIA is cerebral atheroscierosis, cervical artery plaque number, and intracranial or extracranial vessel sitenosis. There is a significant difference between the elders and non-e)ders for these factors. with a pattern of more close relation for the former. Conclusions lt is valuable to diagnose TIA in the intermit and it is necessary to treat the TIA patients timely. SPECT plays an importam role m treating TIA and preventing irreversible change. ft may be an effective method to diagnose TIA. The major factors of TIA are atherosclerosis, intracranial or extracranial vessel stenosis, and cervical artery plaque number. The pathology of extracranial vessls in TIA in our country is slighter than that in Euro-American countries.
