What is microvascular decompression?

microvascular decompression (MVD) is a procedure used as a trigeminal treatment of neuralgia. Trigeminal neuralgia is a neuropathic disease with symptoms of intense face pain. One of the causes of this disorder is the compression of the cranial nerve in, trigeminal nerve, enlarged blood vessels such as superior brain artery. Microvascular decompression, also called Janetta procedure, works insulation or increased distance between blood vessels and nerve. As a neurosurgical procedure, it includes craniotomy, opening the skull to reveal the fifth cranial nerve and neighboring blood vessels. Paroxysms of pain in trigeminal neuralgia are assumed to be associated with the pulsation of the involved blood vessels that compress the nerve. The department of nervous and blood vessels is therefore necessary to mitigate the symptom of pain. The patient's head then turns so that the symptomatic party is accessible neurosurgone. Patient brain activity, face and hearing function is performed during the procedure.

Then a cut that exposes the brain, called the dura and part of the brain known as the brain. In a microscopic autopsy, a trigeminal nerve is exposed and mobilized is an offensive blood vessel, which may be superior to the cerebral artery or branch of petrosal vein. A small fungal material is then inserted between the container and the nerves to make the compression easier.

Not all patients with trigeminal neuralgia can undergo microvolial decompression. The physician usually suggests as a candidate for this procedure, if the patient has trigeminal neuralgia that cannot be controlled by medication and other treatments, facial pain, which only affects the trigeminal nerve, or all three divisions, and symptoms recurrence after graduated procedures such as percutaneous rhizotomy or radio. Patients with basic health, hearing loss or multiple sclerosis can be excluded as candidates.

SUCCESS RIGHTSti microvolial decompression varies, but this procedure can provide a relief of up to 95% of patients. For ten years ponies, about 68% maintain relief from symptoms, but about 32% have a recurrence of symptoms. Microvascular decompression is non -destructive and has the best potential for long -term pain relief among available trigeminal neuralgia. It has a low risk of complications such as hearing loss, insensitivity of the face, stroke and infection.
