The atlantoaxial and intracranial segments of vertebral artery (V(3-4)) are winding around their peripheral structures. Their panorama is not easy to be observed in surgery. CT angiography (CTA) shows some advantages in this aspect. So, the aim of this study is to reveal the three-...
The vertebral artery (VA) provides segmental vertebral and spinal column blood supply; cranially, it continues with the basilar artery (BA), providing supply to the posterior fossa and the occipital lobes. Of the four segments of the VA, the two pertinent to the CCJ are the V3 and V4. ...
respectively(P>0.05).Conclusion With a suitable scanning and post-processing technique both methods are useful in showing the vertebral artery and the morphologic change of the blood vessel.MRA shows a high value in evaluating vertebral artery more comprehen...
Objective To understand the features of CTA in normal and abnormal vertebral artery.To investigate the clinical value of angiography with CTA to TIA.Methods After peripherical intravenous administration of contrast agent,then to perform scaning of 23 normal and 41 patients with TIA or suspected and ...
caton.Conclusion:3D-CTA is superior to other angiography method to display cong enital abnormalities and sclerosis of the vertebral artery,and we think that the cogenital abnormalities and sclerosis are the important inducing factors to the cervical spondylosis at the origin of the vertebral artery....

The Vertebral Artery is defined as a major blood vessel that is divided into four segments, extending from the subclavian artery to the foramen magnum, supplying the brain and deep neck muscles with oxygenated blood. AI generated definition based on: Imaging in Spine Surgery, 2017 ...
CTA in the detection and quantification of vertebral artery pathologies: a correlation with color Doppler sonography. Neuroradiology 2007; 49: 645-50.Puchner S, Haumer M, Rand T, Reiter M, Minar E, Lammer J, et al. CTA in the detection and quantification of vertebral artery pathologies: a ...
Fenestrations of the vertebral artery are mostly found at the upper cervical or intracranial segments. We present a rare case of vertebral artery fenestration at the lower cervical (C4–C6) segment, which showed a double-lumen appearance on ultrasonography. Computed tomographic angiography (CTA) and...
