在CT未引进以前对于SCA(小脑上动脉)分布区梗塞很少做出诊断。本组三例SCA分布区的小脑梗塞表现有几个不同征象:发病的特征是以急性步态失调伴有轻度或无眩晕。由于小脑上蚓部和小脑半球上部的损害以双侧肢体共济失调和下跳性眼震,躯干和步态失调为主要征象。研究表明SCA分布区的小脑梗塞,远端基底动脉的分布区是一个高发的区域。脑干的梗塞只是潜在的破坏。合并症很少见到,可能由于梗塞小,小脑占位效应小或没有之故。临床症状有时出现病灶对侧听力减退、面肌无力及同侧Horner’s征,没有小脑水肿引起的脑干受压。CT显示双侧小脑半球上中部关
Little is diagnosed with infarction in the SCA (upper cerebellar artery) territory before CT is introduced. The group of three cases of SCA distribution of cerebellar infarction showed several different signs: The incidence of acute gait disorders associated with mild or no vertigo. Due to cerebellar vermis and cerebellar hemisphere upper damage to the bilateral limb ataxia and hopping nystagmus, trunk and gait disorders as the main signs. Studies have shown that SCA distribution of cerebellar infarction, distal basilar artery distribution is a high incidence area. Brainstem infarction is only a potential damage. Comorbidity rarely seen, may be due to small infarcts, cerebellar placeholder effect is small or no reason. Clinical symptoms sometimes appear contralateral hearing loss, facial weakness and ipsilateral Horner’s sign, no cerebellar edema caused by brainstem pressure. CT showed bilateral middle cerebellar hemispheres
