Migraines have been around since ancient times. History records that Cao Cao had migraines during the Three Kingdoms, and had recurrent headaches. In modern society, frequent migraines are not uncommon. According to statistics, the incidence of frequent migraine is about 10%. But in terms of treatment, the effect is not ideal. Frequent migraine belongs to the category of intractable migraine. Emotional tension, overload of mental stress, overexertion and poor life and diet and habits may trigger migraine. Modern medical research confirms that it is a chronic neurological disorder. In normal people, the blood vessels and nerves on the scalp are in a companion relationship and do not compress each other, while in migraine patients, the blood vessels or other tissues on the scalp may cause compression of the nerves by jamming, entangling, or adhesions. This compression does not directly lead to migraine attacks, but when the blood vessels in the compressed section are overly diastolic due to various reasons such as physical fatigue, mood swings or improper diet, as well as endocrine changes that cause abnormal changes in the concentration of pain-causing neurotransmitters in the blood, the blood vessels in the compressed section produce an abnormal stimulation of the nerves and trigger pain attacks. For frequent migraines, microvascular decompression is introduced. Under a microscope, the painful point is found before surgery, and then the responsible blood vessel is isolated, removed or blocked under the microscope, thus reducing the vasodilatation’s irritation to the nerve.
