Methods The ultrasonographic characteristics of vertebral artery occlusion in 11 patients diagnosed by ultrasound were analyzed retrospectively. Results It was confirmed by 3D MRA that 10 cases were vertebral artery occlusion and 1 was stenosis of vertebral artery.The accuracy of ultrasonography was 91%(10/11).Vertebral artery occlusion mostly occurred on the right side (80%).Two thin parallel hyperechoic lines of the walls,echogenic material throughout the lumen and no pulsate were showed in all.Hyperechoic plaques with shadows were seen in 3 patients at the walls with no blood flow signals. Conclusion Ultrasonography was the first and creditable noninvasive imaging method in diagnosis of vertebral artery occlusion.Read More
