Migraine is the most common type of primary headache in clinical practice. According to statistics, the prevalence of migraine in the population is 9.3, and almost one in ten people suffer from migraine. Migraines are very dangerous, not only because they cause severe and frequent head pain, but also because they are psychologically and mentally devastating. Many patients become depressed, and some are tortured to the point of death, or even commit suicide. So what causes this migraine? Many factors in life can trigger migraine attacks, such as excessive work pressure, fatigue, emotional stress, excitement, irregular diet, exposure to wind and cold, consumption of soy-based foods, pickled foods, chocolate, etc., and drinking coffee and red wine, all of which can easily trigger migraine attacks. However, these factors are only the triggering factors of migraine. According to scientific research, migraine is caused by abnormal compression, entanglement, adhesion, etc. of certain blood vessels on the patient’s scalp to the related nerves, which, together with the influence of these triggering factors or under some other conditions, can cause changes in the concentration of pain-causing transmitters in the blood and stimulate the nerves, resulting in an attack of headache. So migraine sufferers should try to avoid these triggers in their lives to prevent migraine attacks. But then again, many things are sometimes inevitable. So it is still important to seek the right way to solve the problem. Microvascular decompression is used to treat migraines by finding the vascular nerve compression points under a microscope, relieving the compression, and isolating and protecting the nerves. This minimally invasive procedure is less invasive and has a faster recovery, making it an effective treatment for intractable migraines.
