Microvascular Decompression (MVD)
Microvascular decompression (MVD) is a surgical procedure that relieves abnormal compression of a cranial nerve. It is performed to treat trigeminal neuralgia, vagoglossopharyngeal neuralgia, and hemifacial spasm. These conditions are often caused by an artery or vein compressing the nerve root as it leaves the brainstem. When compressed, normal nerve impulses can recruit nearby nerve fibers and send faulty messages. Medications often provide relief to patients with these conditions, but when medications become ineffective or cause serious side effects, one treatment option is MVD.
