#Chiari malformation type 3 how to

The classification of Chiari malformation recognizes five subtypes:Д¬hiari type 0 malformation: characterized by an alteration in Cerebro Spinal Fluid (CSF) hydrodynamics at the level of the foramen magnum. On the other hand, it is important to develop a consensus regarding the management and the therapeutic approach of these malformations, particularly, considering that in many cases they remain asymptomatic for years.ДЄ classification of the Chiari malformation and related issues about the disease, such as diagnosis and treatment is discussed below, as well as their social and health concernings. There are two types of therapies to treat these malformations: surgical therapy, that should be considered for symptomatic patients and which main goal is the decompression of the foramen magnum and non-surgical therapy, used to relieve the symptoms caused by neuropathic pain.ДЄlthough malformations of the craniocervical junction are considered rare diseases (RDs) due to their low incidence, the increasingly frequent use of neuroimaging techniques in clinical protocols has led to such a large increase in the diagnosis of tonsil herniations that there is discussion in the medical literature about whether the prevalence figures known for these diseases should be revised. In most cases syringomyelia is due to craniocervical malformations, mainly Chiari malformation and basilar impression, so all the problems due to those conditions added to those of syringomyelia, can severely affect the patient's quality of life if adequate and timely measures are not taken. Although most authors consider the average at presentation approximately 35 years, symptoms onset can occur at any age, from 1 year to older than 60 and are highly uncommon in people older than 65 years. The disease affects both genders, although with slight predominance in women, and all races. The word syringomyelia means reed- or flute-like spinal cord.

In general, patients complain of recurrent headache, cervical pain, and progressive spasticity of the lower limbs.ДЄmong the many malformations of the craniocervical junction, Chiari type I syndrome and syringomyelia are noteworthy because of their prevalence and the seriousness of their symptom. Symptoms typically appear during adolescence or adulthood, and are not usually accompanied by hydrocephalus.

The most extreme form consists of the herniation of structures of the lower cerebellum, the cerebellar tonsils, and brain stem through the foramen magnum, in such a way that parts of the brain enter the spinal canal, thickening and compressing it. In the mid-1970s, the term Chiari was again used to name the syndrome.Д¬hiari syndrome is a developmental malformation of the occipital mesodermal somites that can be associated to syringomyelia and hydrocephalus. The most detailed original description, however, was made by Chiari in 1891. The first case was described by Cleland in 1883. It is necessary that the physicians involved in the care of people with this condition comprehensively approach the management and follow-up of the patients, and that they organize interdisciplinary teams including all the professionals that can help to increase the quality of life of patients.ДЇor several decades, the eponyms Arnold and Chiari have been used as synonyms to define conditions with ectopia of the cerebellar tonsils below the level of the posterior edge of the foramen magnum.

It is important to determine the needs of the patients in terms of health-care, social, educational, occupational, and relationship issues, in addition to those derived from information aspects, particularly at onset of symptoms.Д¬urrently, there is no consensus among the specialists regarding the etiology of the disease or how to approach, monitor, follow-up, and treat the condition. Non-pharmacological therapies are primarly based on spinal or peripheral electrical stimulation. Pharmacological therapy use drugs that act on different components of pain. The most effective therapy for patients with Chiari type I malformation/syringomyelia is surgical decompression of the foramen magnum, however there are non-surgical therapy to relieve neurophatic pain: either pharmacological and non-pharmacological. The diagnosis of Chiari type I malformation in patients with or without symptoms is established with neuroimaging techniques.

Symptoms may vary between periods of exacerbation and remission. The onset of Chiari syndrome symptoms usually occurs in the second or third decade (age 25 to 45 years). Chiari disease (or malformation) is in general a congenital condition characterized by an anatomic defect of the base of the skull, in which the cerebellum and brain stem herniate through the foramen magnum into the cervical spinal canal.
