Many patients with cervical vertigo symptoms. Symptoms attack, Can rotation, such as shaking feeling of vertigo and the occurrence and development and increase. Neck and activities directly related to potential changes, especially in the neck rotation suddenly when the old or induced or exacerbated, to the side easily lead to a seizure, and then to the contralateral someone will be able to alleviate symptoms such as dizziness one-off vertigo. Patients with serious, or even have a damping - off phenomenon. Damping-off attack as before without any signs, often in patients with a certain posture, neck rotation, suddenly felt dizziness, headache, the two lower limbs immediately unable fell to the ground. Unconscious obstacle to the process of attack, may fall after its own.
Vertigo symptoms of cervical vertebral artery is one of the main symptoms of disease, the incidence of this disease around the 70 percent, damping - off accounted for 5 percent of a 10 percent. To understand the type of cervical vertebral artery disease Why should there be vertigo symptoms, we must from the start with the anatomy of vertebral artery.
Vertebral artery issued since the subclavian artery, sub-paragraph 4 of the foramen magnum entered. Paragraph 1 (cervical) of the subclavian artery issued prior to entering the transverse foramen part of paragraph 2 (vertebra) to wear as part of cervical transverse hole, paragraph 3 (pillow) transverse process since atlas Hole piercing to enter the intracranial part of paragraph 4 (intracranial) to enter part. The bilateral vertebral artery blood flow supply about 10% of a 15% supply the spinal cord and spinal nerve roots organizations such as the blood flow about 90 per cent of the. Flexion and extension of the cervical vertebral artery when tension has little effect on blood supply will not cause obstacles, but to the side of rotation and, due to the increased tension side of the vertebral artery, which supply the brain blood flow reduction at this time, normal the other side of the vertebral artery can be compensated to ensure that the brain, spinal cord and spinal nerve roots, and so the normal blood supply. The type of cervical vertebral artery disease, it may be due to dynamic factors, mechanical factors, vascular factors, and other factors, so that the affected vertebral artery arising from the loss of compensatory ability vertigo.
Power factor, the general type of cervical vertebral artery disease early light or the cause. Because vertebral instability after Hook section of vertebral joints loose, positioner, the side effects of the upper and lower transverse hole, stimulate or oppression from vertebral artery vasospasm, a narrow, distorted or discount Qu change. Mechanical factors, it is, the cause of late. Hook vertebral joints bone hyperplasia, such as direct compression nucleus pulposus extricate himself from the vertebral artery arising from symptoms. Vascular factors, in addition to increasing age after vascular forces weakened, atherosclerotic vascular change and variability, and so speed up the process of the disease causes, but also due to vertebral artery cervical disc degeneration, caused by vertebral gap narrowed its relatively long the problem, this imbalance can produce further vertebral artery discount Qu, thickening and bending, and other changes, thereby affecting the vertebral artery blood flow.
Type cervical vertebral artery disease is due to the above reasons mainly to the vertebral vertigo - basilar artery insufficiency syndrome. In addition to dizziness, the symptoms of damping - off, there are common symptoms of migraine, tinnitus, blurred vision, and so on. Because vertebral artery around with a lot of fiber and at the same time sympathetic postganglionic autonomic nervous system involvement, so often accompanied the gastrointestinal, respiratory and cardiovascular autonomic nervous system disorder, and other symptoms.
However, the vertigo symptoms is not the type of cervical vertebral artery disease alone, otorhinolaryngology, neurology, ophthalmology, and many other diseases can also arise vertigo symptoms like Otogenic vertigo, brain-derived dizziness, eye-derived vertigo, trauma vertigo, somatic diseases caused dizziness and Neurosis, etc.. Add any remaining section of the vertebral artery lesions may also cause these ischemic symptoms, and many other symptoms and easily confused with a variety of diseases, the diagnosis of cervical vertebral artery disease is more difficult.
To be clinically diagnosed, - is at the same time we must pay attention to whether patients with neck pain, neck activities restricted common cervical spondylosis and other general symptoms, X-ray, whether there is a hook vertebral joints bone hyperplasia, deformation intervertebral foramen smaller vertebral trapezoidal section changed or changed, and so has cervical abnormalities; Second, pay attention to the differential diagnosis. This type of cervical disease, due to attack with Meniere's disease, and so there are other similarities with vertigo, it is sometimes necessary in the diagnosis of vestibular function tests conducted ears, hearing, and other specialist inspection to identify. Elderly people suffering from this type of diagnosis of cervical disease, blood vessel flexibility and should consider factors such as vascular sclerosis.
Cervical vertebral artery disease-a reference standard for diagnosis: ① there mainly to the vertebral vertigo - missing hyperlipidemia and basilar artery (or) had cataplexy attacks; ② carotid test positive spin; ③ displayed on the X-ray films with vertebral joints Instability hook vertebral bone or joint hyperplasia; ④ sympathetic with varying degrees of symptoms; ⑤ except Otogenic or eye-derived and other Vertigo; ⑥ except section l vertebral artery caused by the compression of the basilar artery blood supply is incomplete; except ⑦ Neurosis, and other intracranial tumors from blame; ⑧ vertebral artery blood flow charts and EEG only reference value, diagnosed require vertebral artery angiography. Vertebral artery angiography for the main signs of vertebral artery stenosis, or lesions in the vertebral artery segment loss of the original form, representing a small adjacent segments, and a displacement; site or bending under pressure, circuitous or obstruction. Vertebral artery angiography and positioning of surgical procedure to select. In addition, the use of digital subtraction angiography will be more satisfied with the vertebral artery imaging.
