Analysis of risk factors,clinical manifestations and ultrasonic characteristics of vertebral artery dissection / 中风与神经疾病杂志

ABSTRACT

@#Objective　The predisposing factors,clinical characteristics and imaging characteristics of intracranial and extracranial vertebral artery dissection are compared to understand the influence on the location of vertebral artery dissection and the ultrasonic characteristics of different parts.Methods　Forty-four patients with vertebral artery dissection diagnosed in the Department of Neurology of our hospital from June 2017 to June 2021 were selected and divided into intracranial group and extracranial group according to different lesion sites of vertebral artery dissection.The differences in baseline data,susceptibility factors,clinical manifestations and ultrasonic characteristics of the two groups were compared.Results　A total of forty-four patients were enrolled and were divided into intracranial vertebral artery dissection group (n=20 cases) and extracranial artery dissection group (n=24 cases).The incidence of massage or trauma in extracranial was significantly higher than that in intracranial (P=0.01).Headache symptoms were more common in intracranial group (P=0.04),however there were no significant differences in clinical features such as dizziness,hemiplegia,dysphagia and Horner’s sign between the two groups (P>0.05).Intramural hematoma was the most common ultrasonic characteristics in patients with vertebral artery dissection,and Ultrasonography was significantly limited in the intracranial segment.It is simple to operate,non-invasive,inexpensive and easy to popularize.Conclusions　The predisposing factors and clinical manifestations of vertebral artery dissection are not identical in different parts.
