目的 对22例短暂性完全遗忘综合征病人进行临床观察,并探讨其发病机理。方法 我们根据Caplan诊断标准诊断了22例TGA病人,行多普勒,头CT、MRI、MRA,脑电图,血流变等检查,分析了检查结果,查找TGA病因。结果 22例患者均行多普勒检查,18例示椎-基底动脉供血不足,4例正常。头CT检查,11例有腔隙性脑梗死,3例脑萎缩,8例未见异常。其中6人同时进行头MRI检查,其中3人腔隙性脑梗死,3例正常。20例脑电图检查,4例异 常,血液流变学检测,均有不同程度血液流变学改变。结论TGA经治疗预后良好。
Objective To investigate the clinical manifestations of 22 patients with transient complete amnestic syndrome and to explore its pathogenesis. Methods Twenty-two TGA patients were diagnosed according to the Caplan diagnostic criteria. Doppler, head CT, MRI, MRA, EEG, and blood rheology were used to diagnose TGA patients. The results of the examination were analyzed to find out the cause of TGA. Results Twenty-two patients underwent Doppler examination, while 18 patients showed insufficient blood supply to vertebrobasilar artery and 4 patients were normal. Head CT examination, lacunar infarction in 11 cases, brain atrophy in 3 cases, and no abnormalities in 8 cases. Six of them underwent head MRI at the same time, including 3 lacunar infarcts and 3 normal controls. 20 cases of EEG examination, 4 cases of abnormal, hemorheological tests, have varying degrees of hemorheological changes. Conclusion TGA has a good prognosis.
