Syringomyelia is a chronic myelopathy with the formation of cavities in the spinal cord. The most common cause of syringomyelia is the obstruction of the cerebrospinal fl uid tract at the craniovertebral junction level in patients with Chiari malformation. The main method of treatment of syringomyelia is surgical, aimed at stopping the progression of the disease. To date, controversial data on the postoperative regression of myelopathic symptoms and factors contributing to a positive clinical outcome are presented in the world literature Goal of the study: to assess the dynamics of myelopathic symptoms of syringomyelia at the postoperative stage.Material and methods. 44 patients with syringomyelia associated with Chiari 1 malformation, who underwent decompression of the posterior cranial fossa and had positive postoperative radiological dynamics of the syringomyelitis cavity were included to our retrospective study. Patients were evaluated by clinical and MRI parameters at the preoperative and distant postoperative stages.Results. Analysis of clinical and MRI indicators at the preoperative and remote postoperative stages allowed us to determine the frequency of regression of myelopathic symptoms and to identify it’s main dynamics predictors.
Syringomyelia is a chronic disease with progressive cavitation and clinical presentations of spinal cord injury. The paper describes clinical cases of a rare benign variant of syringomyelia with spontaneous cavity collapse. The peculiarity of the described clinical cases is childhood-onset of the disease, lack of progression and/or development of myelopathic symptoms, and signs of syringomyelia cavity collapse according to magnetic resonance imaging findings. The authors designate this childhood-onset variant of the disease as abortive. The tendency towards collapse in the cavity in these patients may be due to a single pathogenetic mechanism, which is of interest for a further investigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
