摘要
目的探讨小脑型分水岭梗死临床特点及影像学特征。方法回顾性分析32例病人的临床、CT和MRI资料。结果小脑型分水岭梗死临床大多表现为头晕、头昏,头颅MRI、DWI(弥散加权成像技术)检查梗死灶阳性率为100%,行MRA(磁共振血管成像)检查血管异常阳性率高,经治疗31例恢复良好,1例发展为进展性卒中而死亡。结论颅内动脉的狭窄、变异和血流动力学改变与小脑型分水岭梗死关系密切,早期行DWI检查可以明确病灶部位,MRA技术可作为颅内血管的初筛检查,积极综合治疗可以改善小脑型分水岭梗死预后。
Objective To explore the the clinic and imaging characteristics of cerebellar watershed infarction. Methods We reviewed 32 patients with clinical data,computerized tomography （CT） ,and magnetic resonance imaging （MRI）. Results Dizziness and vertigo were commonly clinical manifestions in patients with eerebellar watershed infarctions, diffifused weighted imaging（DWI）were sensitive in detecting the infarctions with 100 percent. Magnetic resonance angiography（MRA） in the patients had positive results,all patients had optimistic outcome after therapy,except that one died with progressive infarction. Conclusion Cerebral artery stenosis,vessel malformation and abnormal blood rheology are associated with cerebellar watershed infarction. DWI can detect the infaetion early, MRA can be used to evaluate the vessels generally. Cerebellar watershed infarction has optimistic outcome with positive comprehensive therapies.
