Breaking Barriers for Cerebrospinal Fluid Flow in Chiari Malformation Type I: “What and How Much Is Enough?” A Retrospective Analysis of 74 Cases

Indian Journal of Neurosurgery, 2018
Introduction: Chiari malformation type I is a collection of hindbrain abnormalities, for which natural history of the disease process is not clear. The challenge is to identify which patients will benefit most from posterior fossa decompression.

Cranio-cervical decompression associated with non-instrumented occipito-C2 fusion in children with mucopolysaccharidoses: Report of twenty-one cases

North American Spine Society Journal, 2022
Background: Mucopolysaccharidosis (MPS) is a multisystemic storage disorder of glycosaminoglycan deposits. Infiltration of the dura mater and supporting ligaments caused spinal cord compression and consecutive myelopathy, especially at the cranio ...

Fourth ventricular stenting in foramen magnum decompression for type 1 Chiari malformations with syringomyelia. [PDF]

Surg Neurol Int
Background: Chiari malformation type 1 (CM-1) with syringomyelia is a common craniocervical abnormality and in symptomatic patients, there is ongoing debate regarding the optimum surgical strategy for decompressing the foramen magnum. The placement of a fourth ventricular-subarachnoid stent is a novel approach intended to increase symptom response ...

Surgical Management of Chiari Malformation Type I and Instability of the Craniocervical Junction Based on Its Pathogenesis and Classification

Neurologia Medico-Chirurgica, 2022
We investigated the mechanism underlying Chiari malformation type I (CM-I) and classified it according to the morphometric analyses of posterior cranial fossa (PCF) and craniocervical junction (CCJ).

Unusual Complication of the Foramen Magnum Decompression

Nepal Journal of Neuroscience, 2019
The pathophysiology of Chiari-Imalformation lies with the abnormal CSF flow across Foramen magnum and Foramen magnum decompression (FMD) restores this flow. However, recent data suggests that FMD itself can alter the CSF dynamics in an abnormal fashion resulting in raised intracranial pressure. We report such a case where FMD has led to the development

Delamination technique together with longitudinal incisions for treatment of Chiari I/syringomyelia complex: a prospective clinical study

Cerebrospinal Fluid Research, 2009
Background Treatment modalities in Chiari malformation type 1(CMI) accompanied by syringomyelia have not yet been standardized. Pathologies such as a small posterior fossa and thickened dura mater have been discussed previously.
