Microvascular decompression is a surgical procedure typically used to relieve symptoms of trigeminal neuralgia, hemifacial spasm, and other disorders caused by the compression of nerves by blood vessels in the brain. During the procedure, a neurosurgeon carefully moves the offending blood vessel away from the affected nerve, reducing or eliminating the pressure causing the symptoms. Microvascular decompression is considered to be a highly effective treatment option for certain neurological disorders and can provide long-lasting relief for patients.
