Prevalence of High Riding Vertebral Artery and Morphometry.

Vertebral artery test is used in physiotherapy to test vertebral artery blood flow, searching for symptoms of vertebral artery insufficiency, various other artery diseases. The leading theory behind this test is to maximally stress the opposite vertebral artery by stretching it to decrease space in lumen of the artery.

Vertebral artery fenestration: This is when the lumen, or inside of the artery, actually splits into two either inside or outside of the cranium. Also very rare—it’s only seen in between 0.23% and 1.95% of the population—it’s largely believed to be harmless, though some links have been found with certain kinds of brain aneurysms.The vertebral artery test (VA T) is commonly used to screen for VBI before performing high velocity thrust (HVT) and non- HVT techniques ( 4, 7, 12, 24, 25 ).The lower vertebral artery measurement was taken at C5-6 level, which is typically the first entry level of the vertebral artery into the transverse foramen of the cervical spine .17, 20 The transducer was placed longitudinally at the anterolateral aspect of the neck and the probe shifted laterally until the cervical transverse processes were visualized and the entry of the vertebral artery.


The Vertebral Artery Test or Wallenberg Test is a physical exam for vertebral artery insufficiency. Commonly, the VA test involves cervical spine motion to an end-range position of rotation, extension or a combination of both. At this point, the physician assesses for vertebrobasilar insufficiency (VBI) symptoms. If the patient has VBI symptoms during the test, it is considered a positive.The vertebral artery (VA) is a branch of the subclavian artery, which runs along the cervical spine and ends intradurally at the junction with the basilar trunk. It is subdivided into four segments: V1 segment (ostial segment) from origin to C6, V2 segment (transversary segment) from C6 to C2, V3 segment (suboccipital segment) from C2 to the dura mater of the foramen magnum (FM) and V4 segment.

The vertebral arteries are major arteries of the neck. Typically, the vertebral arteries originate from the subclavian arteries.Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery.As the supplying component of the vertebrobasilar vascular system, the vertebral arteries supply blood to the upper spinal cord, brainstem.

Vertebral artery occlusions fall under the umbrella of Vertebrobasilar Disease (VBD), otherwise known as Vertebrobasilar Insufficiency (VBI). The condition is defined by inadequate blood flow to the rear section of the brain responsible for coordination, vision, balance, consciousness and other necessary functions.
