脑MRI检查使小脑上动脉(SCA)供应区的梗塞的诊断变得容易。作者对仅表现为小脑症状的SCA梗塞的10例病人的临床资料进行了分析,试图解释其基本的病理生理。 全组10例,均为男性,50～72岁,突然发病,MRI示小脑前叶梗塞。排除了基底动脉闭塞的病人。均在发病后1个月内基本相同的时间行脑MRI及脑血管造影术,MRI在发病后3周内检查,脑血管造影术在发病后1～14天内检查。所有病人均行包括心电图、经胸超声心动图和holeter监测的心脏检查。 病变部位在左侧5例,右侧4列,双侧1例。发病时主要症状恶心呕吐3例,头晕8例,耳鸣1例,头痛3例,这些症状在数天内消失。所有病人有小脑性共济失
Brain MRIs facilitate the diagnosis of infarcts in the upper cerebellar artery (SCA) supply. The authors analyzed the clinical data of 10 patients with SCA infarction, which showed only cerebellar symptoms, in an attempt to explain its underlying pathophysiology. The whole group of 10 patients, both men, 50 to 72 years old, sudden onset, MRI showed cerebellar infarction. Patients with occluded basilar artery were excluded. All patients underwent brain MRI and cerebral angiography at the same time within 1 month after onset. MRI was inspected within 3 weeks after onset and cerebral angiography was performed within 1 to 14 days after onset. All patients underwent cardiac exams including electrocardiogram, transthoracic echocardiography and holeter monitoring. Lesions in the left side of the 5 cases, 4 on the right side, bilateral in 1 case. The main symptoms of nausea and vomiting in 3 cases, 8 cases of dizziness, tinnitus in 1 case, 3 cases of headache, these symptoms disappear within a few days. All patients have cerebellar ataxia
