单纯性丘脑梗死的临床特点和脑血管造影分析

Analysis of the clinical characteristics and cerebral angiography of patients with simple thalamus infarction

目的分析不同区域急性单纯性丘脑梗死的临床特点以及脑血管造影表现。方法回顾性分析48例完成全脑血管造影急性单纯性丘脑梗死患者的临床资料。结果 48例患者,24例为丘脑膝状体动脉梗死,12例为丘脑旁正中动脉梗死,8例为丘脑结节动脉梗死,4例为脉络膜后动脉梗死。48例患者中仅13例全脑血管造影结果未见异常,同侧大脑后动脉异常13例,共26条基底动脉近端的后循环血管出现明显狭窄。丘脑膝状体动脉梗死以偏身麻木表现为主,丘脑旁正中动脉梗死以意识水平下降和眼球运动异常为主,丘脑结节动脉梗死以语言功和对侧肢体运动功能异常为主,脉络膜后动脉梗死以视野改变为主,丘脑旁正中动脉梗死和丘脑结节动脉梗死患者简易智力量表评分均有不同程度下降。结论丘脑不同动脉供血区梗死可引起不同的症候群,脑血管造影是对丘脑梗死患者血管评估的重要手段。

Objective To investigate the clinical characteristics and cerebral angiography of patients with simple thalamus infarction. Methods The data of 48 patients with simple thalamus infarction accomplishing the cerebral angiography were retro- spectively analyzed. Results There were 24 cases of thalamic geniculate body artery infarction, 12 cases of thalamic paramedian artery infarction, 8 cases of thalamic polar artery infarction and 4 cases of posterior choroidal artery infarction in 48 patients. The results of cerebral angiography were 13 cases of abnormal ipsilateral posterior cerebral artery, 26 cases of stenosis vessels in posterior circulation and 13 cases of no abnormality. The clinical symptom of thalamic geniculate body artery infarction was hemianesthesia, and the clinical symptoms of thalamic paramedian artery infarction were disturbance of consciousness and eye- ball movement abnormalities. The clinical symptoms of thalamic polar artery infarction were thalamic aphasia and contra lateral motor disorders, and the clinical symptoms of posterior choroidal artery infarction were vision changes. Conclusion There are different characteristic syndromes in patients with simple thalamus infarction, and cerebral angiography is an important vascular method assessing simple thalamus infarction.
