As a common disease of modern people, many migraine patients have been taking conservative treatment to suppress or reduce the pain and some accompanying symptoms by medication, which is effective for mild migraine and can get temporary relief after taking medication. However, in patients with intractable migraine, the effect of medication is no longer obvious, and even if the patient takes too much medication for a long time, the kidneys and other organs will be damaged to different degrees, which is not worth the loss. In recent years, with the emergence of microvascular decompression, more and more migraine patients have seen the light of hope, and the successful treatment cases of migraine have gradually entered the public eye and become more and more well-known. How is migraine surgery done? Are there any risks? The pathogenesis of migraine has not been accurately determined yet, and many experts and scholars have their own opinions and different positions. The neurovascular theory explains that migraine is caused by the adhesion, compression or entanglement of blood vessels and nerves on the scalp, and in such an abnormal state, when stimulated for some reason, painful transmitters are released, resulting in painful spots and migraine. The microvascular decompression procedure is the principle of this theory, in which the nerve compression by blood vessels or other tissues is found, and the relationship is removed and the nerve is isolated to prevent future attacks. After the surgery, the patient’s headache will be significantly improved. Microvascular decompression is a minimally invasive procedure with an incision of only about 3-5 cm, with minimal trauma and quick recovery.
