Microsurgical ressection for parasagittal meningiomas with preservation of the parasagittal sinus and excelent neurovascular control Ressecção microcirúrgica dos meningiomas parasagitais com excelente controle vascular e preservação do seio longitudinal superior

Objective: It was to observe whether a microsurgical gross total removal (GTR) of a parasagittal meningioma (PSM) outside the sinus is a safe and efficient procedure. Method: We identify 58 parasagittal meningiomas patients. Medical charts, operative reports, imaging studies and clinical follow-up...

Description
Summary:Objective: It was to observe whether a microsurgical gross total removal (GTR) of a parasagittal meningioma (PSM) outside the sinus is a safe and efficient procedure. Method: We identify 58 parasagittal meningiomas patients. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed. Results: GTR of the mass was achieved in 45 (77.7%) instances. The surgical mortality rate was 1.7%. The median follow-up time was 63 months. Conclusion: The surgical approach used in this group of patients afford that the great majority of tumors could be totally removed with low mortality, proving to be safe and effective.<br> Objetivo: Foi observar se a ressec&#231;&#227;o microcir&#250;rgica extrassinusal dos meningiomas parasagitais &#233; uma t&#233;cnica segura e efetiva. M&#233;todo: Foram estudados 58 pacientes portadores de meningiomas parasagitais. Quadros m&#233;dicos, relat&#243;rios de opera&#231;&#245;es, exames de imagem e seguimento cl&#237;nico foram revisados. Resultados: A remo&#231;&#227;o total da les&#227;o, fora do seio, ocorreu em 45 casos (77,7%). A taxa de mortalidade cir&#250;rgica observada nesta s&#233;rie foi de 1,7%. O tempo m&#233;dio de seguimento foi de 63 meses. Conclus&#227;o: A estrat&#233;gia microcir&#250;rgica empregada propiciou a remo&#231;&#227;o total dos meningiomas na maioria dos pacientes, com baixa mortalidade e morbidade, mostrando ser segura e efetiva.
