The Clinical Features Of 232 Patients With Vertigo And Cause Analysis

Objective: to investigate the etiology and clinical characteristics of patients with vertigo.Method: collecting 232 cases of patients with vertigo,according to clinical data,symptoms,signs and vestibular function examination,listening,head computed tomography(CT)or magnetic resonance imaging(mri),transcranial doppler ultrasound,carotid ultrasound and other auxiliary examination were analyzed retrospectively,the etiology and clinical features are discussed.Results:(1)232 cases of patients in the youngest age 7,the biggest 90 years old,the average age of 60.1 years,the incidence peak age between the ages of 60-69,a total of 63 cases(27.16%);Followed by between 50 and 59,a total of 62 cases(26.72%);In less than 40 years old and over 80 of these two fewer age onset,the 17 cases,7.33% each.(2)the male patients 114 cases,118 cases of women,men accounted for 49.1%,women accounted for 50.9%,women more than men.(3)the vertigo,105 cases of hypertension patients(45.2%),diabetes mellitus,35 cases(15.1%),combined hyperlipidemia of 30 patients(12.9%),smokers 41 cases(17.7%),were men;Drinkers,26 cases(11.2%),were men.(4)the most common symptoms are nausea,75 patients with vertigo,68 cases(32.3%),vomiting(29.3%),tinnitus,38 cases(9.9%),see things revolving 28 cases(12.1%),with hemiplegia,drinking water choke to cough,hearing loss,structural disabilities is relatively rare.(5)line of vestibular function examination in 99 patients is normal(that is,the semicircular canal and overall balance functions are fair),30 cases(30.3%);Was abnormal,semicircular canal function abnormalities in 61 cases,abnormal function of overall balance of 47 cases,2 cases of loss of function.BPPV was diagnosed in 53 cases(53.5%),MD7 cases(7.1%),VM18 cases(18.2%),12 cases of posterior circulation ischemia(12.1%),VN9 cases(9.1%).Line electricity measurement,a total of 80 cases of listening,the result is normal in 5 cases,abnormal in 75,there are high frequency hearing loss in 38 cases,acoustic nerve deaf 34,mixed neural deaf in 3,accounted for 47.5%,42.5% and 42.5%,respectively,without conduction of nerve deafness.(5)line of TCD inspectors,a total of 52 patients with vertigo,are abnormal,the vertebral artery blood flow speed increase Kuai Zhe 26 cases,13 cases of blood flow velocity slowed,middle cerebral artery blood flow velocity increased Kuai Zhe 8 cases,slow blood flow velocity in 1 case,involving the proportion of patients is less,the anterior cerebral artery blood flow velocity increased Kuai Zhe 4 cases,slow blood flow velocity in 0.The ratio of involvement before and after the cycle is about 1:3.Neck vascular colour to exceed examination of a total of 136 cases,abnormal in 122(89.7%)and pathological changes of film change/patches within blood vessels more give priority to,hardening of the arteries + plaques in 69 cases(50.7%),intima-media change in 53 cases(39%),vascular change and hardening of the arteries intima-media + plaque formation of the proportion of 1:1.3;(6)the brain MRI/CT inspectors,a total of 163 cases,the results indicate that the most common lesion is lacunar cerebral infarction,a total of 72 cases(44.2%);Demyelinating lesions in 70 cases(42.9%);Brain atrophy in 48 patients(29.4%);New cerebral infarction,15 cases(9.2%),of which 7 cases of cerebellar infarction,pons infarction in 5 cases,1 cases thalamus infarction,right temporal occipital lobe infarction in 1 case,1 case of left basal ganglia infarction;Cerebral hemorrhage 4 cases;Meningioma,2 cases;Cavity plate saddle in 5 cases.(7)the main disease cause vertigo for posterior circulation ischemia(PCI),a total of 129 patients,the proportion is 55.6%,the rest of the etiology of BPPV,VM,MD,VN,accounted for 22.8%,9.1%,4.3% and 22.8% respectively.Conclusion: the onset of vertigo increased with the increase of age,50-69 as the peak onset age,reached after the 80-year-old is rare,the onset of female than for male.More than one-third of the vertigo in patients with hypertension disease.Patients with vertigo,the most common symptoms are nausea,followed by vomiting,tinnitus,vision rotation,numbness.Vestibular function examination in the most common reason for BPPV,the second for the VM.Line electric audiometry examination of patients with high frequency hearing loss,acoustic nerve deafness for common.TCD examination suggests the brain blood vessels to narrow is seen,the most commonly affected parts for vertebral basilar artery,posterior circulation system before the circulation system for middle cerebral artery.Neck ultrasound vascular pathological changes is given priority to with hardening + plaques,brain MRI/CT results indicate that the most common lesion is lacunar cerebral infarction.Cause the main disease because of posterior circulation ischemia vertogo,the rest of the etiology of BPPV,VM,MD,VN.
