Tratamiento Quirúrgico de los Meningiomas Espinales

Objective: We make a presentation about our experience in spinal meningiomas surgical treatment. Material and methods: This descriptive-retrospective study included 24 patients with spinal meningiomas diagnosis, surgically treated, from September 2009 to December 2016. Epidemiological data, personal history, symptoms, radiological characters, operative findings, neuropathology description, post operative evolution and degree of resection has been analyzed. Results: Twenty four patients underwent surgery; 83% were female. Lesion localization was 79% in thoracic, 17% in cervical y 4% in lumbar spine. Neuropathology revealed grade 1 (WHO) for all cases. In 63% of all patients, hemilaminectomy was used as surgical approach, reaching a good resection level for all of them (Simpson 1 and 2). Nearly about 66% of the patients showed a good neurological recovery. Average period of follow up was 14.9 months. Conclusion: Surgery is still the gold standard treatment for spinal meningiomas. Hemilaminectomy approach type is useful and valid for lateral implantation tumors. Ventral lesions, with a calcic component and motor deficit present before surgery, are often technically complicated and with a poor prognosis.
