This disease is a complication of various factors that cause irritation or compression of the vertebral artery, resulting in inadequate blood supply to the vertebrobasilar artery as the main symptom. The clinical symptoms are vertigo, headache, sudden collapse, visual impairment, sensory impairment, etc. 1, vertigo is a manifestation caused during head rotation, in which the blood flow of vertebral artery on one side decreases and the compensatory blood supply on the other side increases during head rotation. Therefore, once it is unable to compensate, vertigo can be caused by the reduction of blood supply to the brain when turning the head. 2. The headache is caused by the decrease of blood supply to the basilar artery, which leads to the expansion of blood vessels in the collateral circulation. The headache is more common in the occipital and parieto-occipital areas and can radiate to the temporal areas on both sides. It is mostly throbbing pain or swelling pain. It may be accompanied by nausea, cold sweaty hands, vomiting and other vegetative nervous disorders. 3. Sudden collapse occurs suddenly, without any aura beforehand, and the lower limbs will feel suddenly weak before falling. There is no impairment in consciousness, vision, hearing and other aspects. After the sudden fall, the patient can immediately stand up and move around without any discomfort. 4.Sensory impairment is manifested as facial discomfort, occasional phantom hearing and numbness in the mouth. 5.Visual impairment is mostly sudden blindness, and vision can be gradually restored after a few minutes, which can be explained by ischemia of the posterior cerebral artery, in addition to diplopia and phantom vision. Because of the various manifestations of vertebral artery cervical spondylosis, it is easy to be confused with various diseases and needs to be differentiated from ophthalmogenic vertigo, intracranial tumor, inner ear drug poisoning, neuropathy and other diseases.
