Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain. The posterior circulation supplies the medulla , pons , midbrain , cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex . [ 1 ]
The phenomenon of flow reversal is called subclavian steal or subclavian steal phenomenon, regardless of whether signs or symptoms are present. [1] In this condition, the affected arm may receive blood supply flowing in a retrograde direction down the vertebral artery, potentially compromising the vertebrobasilar circulation.
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.
A rare but severe complication of this disease is vertebrobasilar insufficiency. [7] This is a result of the vertebral artery becoming occluded as it passes up in the transverse foramen. The spinal joints become stiff in cervical spondylosis. Thus the chondrocytes which maintain the disc become deprived of nutrition and die.
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1]
