胼胝体梗死21例临床分析

目的探讨胼胝体梗死的高危因素，临床表现，头颅CT、MRI、TCD、CA表现，预后及其相互关系。方法收集2007．2008年住院病例中的21例胼胝体梗死患者，对其头颅CT、MRI、TCD、CA及临床特征进行回顾性分析。结果本组患者中老年较多，以60～70岁为高发年龄，病因及高危因素主要为高血压病（76．2％）、糖尿病（33．3％），最主要的临床表现为偏瘫、感觉障碍、精神障碍、语言障碍等症状，胼胝体梗死部位以压部多见，常累及基底节区、额叶、顶叶、颞叶等部位。结论胼胝体梗死少见，多有脑血管病高危因素，临床表现因其累及部位不同复杂多样，梗死部位多见于压部，多合并其他部位梗死灶，头颅CT及MRI对胼胝体梗死的诊断有重要价值，临床症状轻微，预后好。

Clinical Analysis of the Corpus Callosum Infarction(a Report of 21 Cases)

Objective To study the risk factor, clinical manifestations, radiologieal feature, TCD, CA and prognosis of Corpus callosal infarction. Methods Radiological feature, TCD, CA and clinic characteristics of 21 patients hospitalized from 2007 to 2008 with corpus eallosal infarction was retrospectively analyzed. Results Among this group, the majority of the patients were old, the corpus callosal infarction had a high incidence rate at the age of 60 -70 year, its etiology and risk factor of corpus callosal infarction including hypertension （76.2%）, diabetes mellitus （33.3 % ） and its major clinical manifestations consisting of hemiparalysis, sensory disturbance, psychonosem and language disorder. The lesions were located mainly in the splenium of corpus callo- sum,always＇ involving basal ganglia, frontal lobe, parietal lobe and temporal lobe. Conclusion Corpus callosal infarction was a rare disease, the patients with the infarction of corpus callosum often had the high risk factors, the clinical manifestations of corpus callosalinfarction varied with lesion sites involved, The site of infarction was most in splenium, Corpus callosal infarction was often coexisted with other area infarctions, head CT and MRI was helpful to the clinical treatment of corpus callosal infarction, clinical symptom was light and prognosis was good.
