Cervicogenic hypertension is due to cervical spine osteophytes, cervical degenerative disease, vertebral instability, atlantoaxial joint subluxation, cervical disc herniation and other reasons, resulting in imbalance of spinal mechanics and imbalance of muscle tension, mild displacement of bone and joint, stimulation or compression of the vertebral artery and sympathetic nerve in the neck, resulting in abnormal cervical sympathetic ganglion or vertebral artery vasodilatation function Disorder, which leads to ischemia and hypoxia and dysfunction of brain cells, secondary to the rise of blood pressure, dizziness, panic, dizziness and other symptoms, or even tinnitus and deafness, chest tightness and panic, dry eyes, insomnia and forgetfulness. It is more common clinically and is one of the important causes of secondary hypertension disease. It is one of the most important causes of secondary hypertension and is receiving more and more attention. About 15% of hypertension patients are associated with cervical spondylosis. I. Causes 1, chronic strain injury: in the development of cervical spondylosis, chronic strain injury is the primary culprit, long-term local muscle, ligament, joint capsule injury, can cause local hemorrhage edema, inflammatory changes, gradually appear in the lesion site inflammatory mechanization, and the formation of osteophytes, affecting the local nerves and blood vessels. 2, trauma: trauma is a direct factor in the occurrence of cervical spondylosis. Often, people already have varying degrees of lesions before trauma, which puts the cervical spine in a highly dangerous state, and trauma directly induces the occurrence of symptoms. 3, bad posture: bad posture is another major cause of cervical spine injury. Long hours of low work, lying in bed watching TV, reading, like high pillows, long hours of computer operation, violent rotation of the neck or head, sleeping in a moving car, these bad posture will make the neck muscles in a long-term fatigue state, prone to injury. 4, developmental abnormalities: cervical spine dysplasia or defects is also one of the causes of cervical spondylosis can not be ignored, Asian species compared to Europeans and Americans The volume of the vertebral canal is smaller, and it is more likely that the spinal cord will be compressed and produce symptoms. In patients with unilateral vertebral artery agenesis, the incidence of vertebral artery-type cervical spondylosis is almost 100%, and the difference is only a matter of time. In addition, skull base depression, hook and loop, congenital fused spine, root canal stenosis, small spinal canal and so on are all congenital developmental abnormalities, which are also important causes of this disease. 5.Inflammatory infection: the pharyngeal cavity is adjacent to the front of the cervical spine and only a thin layer of soft tissue is spaced, and local inflammatory infection is an important cause of local ligament inflammation and joint loosening in the cervical spine. Second, symptom characteristics 1, the onset of the situation: there is no large-scale epidemiological survey data reported, according to the existing case statistics show that most occur in the 20-50 years of age, gradually younger development. In recent years, cervicogenic hypertension has been reported to account for 6.7%-18% of cervical spondylosis and 15-21.9% of hypertension in the population. 2. Blood pressure changes are closely associated with the onset of cervical spondylosis symptoms: when the patient develops cervical spine pain, headache or dizziness, blood pressure rises and falls when cervical spine symptoms are relieved. This feature is especially obvious in the early stage of the disease. This feature gradually decreases in those with long duration of illness. The early stage of cervical spondylosis is almost always reversible, and the reversible changes in symptoms become smaller in the later stage due to bone changes or ligament sclerosis and ossification. 3. Hypotension or unstable blood pressure: There is a long period of hypotension or unstable blood pressure before hypertension. Some people observe this process for 5-30 years, and about 70%-80% become hypertensive. Therefore, any patient with cervical spondylosis who has hypotension or unstable blood pressure should think about the possibility of becoming hypertensive. A small pulse pressure difference is another characteristic of early to mid-stage cervicogenic hypertension, accounting for about 70-80%. 4, more insensitive to antihypertensive drugs: cervicogenic hypertension is not sensitive to antihypertensive drugs, often apply antihypertensive drugs to reduce blood pressure, a short time after rising again, and for cervical spine-related treatment (such as Chinese and Western medicine combined with orthopedic treatment, traction physiotherapy, etc.) is effective, often lasting. 5, cervical spine disease symptoms: such patients mainly have cervical spine disease symptoms, neck pain, restricted movement, and if unilateral rotation or lateral deviation is restricted significantly, it is mostly related to cervical spine or circumflex joint misalignment. The majority of migraine headaches with hypertension accompanying cervical spine symptoms are cervicogenic hypertension, and about 90% of them are cervical joint subluxation or disorders. Most of these patients can recover with manual therapy.
