Objective:This study aims to assess the long-term follow-up outcomes of patients with cervical artery dissection(CeAD),analyzing temporal changes in cervical artery dissection and identifving factors influencing these changes.Methods:The date of 113 adult patients with CeAD who received antiplatelet or anticoagulant therapy from 2015 to 2021.All patients underwent initial and multiple follow-up vascular ultrasound examinations,with a mean follow-up time of(4.7±5.5)months.Clinical and imaging data were recorded for each patient.Results:Among 113 patients,118 dissecting arteries were identified,comprising 63(55.8%)with internal carotid artery dissections,45(39.8%)with vertebral artery dissection,and 5(4.4%)with multiple affected arteries.One patient(0.8%)succumbed,while 84.1%of patients achieved a favorable prognosis(mRS:0～1).Within the first three months,50.9%of patients exhibited improved stenosis.The scores of Modified Rankin Scale(mRS),National Institute of Health Stroke Scale(NIHSS)were recorded.The scores of internal carotid artery dissections[NIHSS=2(0,4)points,mRS=1(0,2)points]showed statistically significant difference compared to vertebral artery dissection[NIHSS=0(0,1)points,mRS=0(0,0.5)points,P<0.01].Conclusion:Cervical artery dissection ultrasound findings exhibit high dynamic change in the initial three months,necessitating vigilant monitoring.Over half of patients with stenosis or occlusion witness varying degrees of improvement in arterial recanalization or stenosis severity after treament.Internal carotid artery dissection causes more severe neurological damage than vertebral artery dissection.
