The Clinical Features And Imaging Comparative Analysis With50Cases Of The Cerebellum Infarction

Objective:To explore the risk factors, clinical manifestations, imaging characteristics ofcerebellar infarction, to investigate the treatment and prognosis of cerebellarinfarction, Improve the diagnosis and treatment of the disease, reduce misdiagnosisand missed diagnosis and improve the prognosis of patients.Methods:Retrospectively analyzed50patients of pure cerebellar infraction hospitalized inthe Department of Neurology of Second Hospital of Jilin University In2013Januaryto2014December,detailed inquiry and record the patient’s medical history, signs andneurology clinical examination data, relevant inspection head CT or MRI andintracranial and extra cranial vascular, analysis the risk factors, etiology，clinicalsymptoms and signs, laboratory examinations, treatment, complications and prognosisof the disease, Statistical analysis and induction and summarization for the data.Result:（1）Pure cerebellar infarction was common in men, male to female ratio was2.57:1, the average age of onset was60.10years old, the average number of days ofhospitalization was12.15days.（2） Cerebellar infarction risk factors in descending order of hypertension,hypercholesterolemia, smoking or drinking history, diabetes, high Hcy,cerebrovascular disease history, family history of cerebrovascular disease, coronaryheart disease, atrial fibrillation.（3）The main symptoms of pure cerebellar infarction appeared dizziness orvertigo, ataxia, visual rotation, headache and cerebellar language; the main signs ofthis diaease contain ataxia, nystagmus, dysarthria or cerebellar language and reduce muscle tension.（4）CT and MRI examination is the main method of diagnosis of cerebellarinfarction; Anatomic site of this group of cerebellar infarction according to theincidence of frequency from high to low in the order: right cerebellar hemisphere, leftcerebellar hemisphere, bilateral cerebellar hemispheres, both cerebellar hemisphereand vermis, cerebellar vermis.（5） In50patients,25cases were cured, significant progress in11cases,progress in5cases,4cases of no change,5cases of worsening.5cases ofdeterioration of the patients of brainstem symptoms in3cases,2cases with thesymptoms of high intracranial pressure,4patients with Department of internalmedicine after conservative treatment3cases were improved,1cases no change,1cases were transferred to the Department of neurosurgery after operation treatmentprogress and discharged, no deaths. Significant progress in the degree of disability in1cases8, the degree of disability and2cases of grade2, the degree of disability and1cases of grade3.Conclusions:（1）Hypertension and hyperlipidemia are the most common risk factors ofcerebellar infarction, In situ thrombosis and atherosclerosis in hypertension andatherosclerosis formation on the basis of embolism is the main cause of the disease.（2） Because of lack of characteristic symptoms and signs in cerebellarinfarction in clinical, therefore, for the sudden onset of dizziness, nausea, vomiting,ataxia, nystagmus and ataxia, should be highly vigilant of cerebellar infarction.（3） For the onset of vertigo patients, patients should be a comprehensivephysical examination, at the same time by CT,head MRI examination as early aspossible, the head MRI examination is superior to the head CT examination,especially DWI and ADC sequence showed the best effect, can reduce themisdiagnosis and missed diagnosis.（4）Conservative treatment for patients with large area cerebral infarction indepartment of internal medicine is poor, and the more severe condition of patients, should be transferred to the Department of neurosurgery operation treatment as soonas possibles.（5）Usually patients with cerebellar infarction timely treatment the prognosis isgood, no sequelae, there are still a few patients appear in brainstem and the symptomsof high intracranial pressure.
