Objective:To investigate the imaging features and diagnostic value of vascular ultrasonography in cervical artery dissection(CAD).Methods:32 patients suspected of CAD were selected from Janaury 2016 to March 2017 in Subei People's Hospital of Jiangsu Province.All patients detected by ultrasonography,high-resolution magnetic resonance imaging(HR-MRI)and(or)digital subtraction angiography.According to the results of HR-MRI and(or)DSA,the sensitivity,specificity and accuracy of vascular ultrasonography in CAD patients were determined.Results:19 patients with a total of 23 dissections(18 internal carotid arteries and 5 vertebral arteries)were confirmed.The direct ultrasound signs of CAD consisted of intramural hematoma(14),double lumens(5),aneurysmal dilatation(3),and intimal flap(1).Indirect ultrasound signs of CAD included stenosis/occlusion in a segment usually not affected by atherosclerosis,increased or decreased pulsatility upstream or downstream to the suspected arterial lesion,50% difference in the blood flow velocity compared to the same segment of the artery on the unaffected side.Compared with HR-MRI and(or)DSA,the sensitivity of ultrasonography for CAD was 91.3%,the specificity was 89.5%,the accuracy was 90.5%.The ROC analysis showed the area under the curve was 0.904.There was a high level of agreement between ultrasonography and HR-MRI(Kappa=0.808).Conclusions: Vascular ultrasonography can diagnose CAD effectively.It has the advantage of minimally invasive,and is useful to clinical practice.
