Eficácia da fenestração da lâmina terminal associada à fenestração da membrana de Liliequist na prevenção de hidrocefalia crônica em pacientes operados na fase aguda por aneurisma cerebral roto

Resumo

Objetivos Hidrocefalia tardia que requer implante de derivação liquórica é frequente após hemorragia subaracnóidea por aneurisma cerebral roto, e contribui para a morbimortalidade tardia. Alguns autores reportam que a fenestração microcirúrgica da Lâmina Terminal, durante a cirurgia do aneurisma diminui a incidência de hidrocefalia tardia.

Material e Método No período de Janeiro de 2010 a Janeiro de 2012 realizamos a fenestração da Lâmina Terminal associada à fenestração da Membrana de Liliequist, em 17 pacientes operados na fase aguda por aneurisma roto. Monitoramos por tomografia a presença de hidrocefalia após 6 e 16 meses.

Resultados Nenhum paciente apresentou hidrocefalia tardia.

Conclusão A fenestração da Lâmina Terminal associada à fenestração da Membrana de Liliequist é eficaz na prevenção da hidrocefalia tardia pós hemorragia subaracnóidea por aneurisma roto.

Abstract

Objectives Chronic hydrocephalus requiring shunt placement is common following aneurysm subarachnoid hemorrhage, and contributes to the late morbidity and mortality Some authors report that microsurgery fenestration of Lamina Terminalis during aneurysm surgery affords a reduction in the development shunt-dependent hydrocephalus.

Methods From January 2010 to January 2012 we performed microsurgery fenestration of Lamina Terminalis and Liliequist's Membrane, in 17 patients operated in the acute phase. CT scans were performed after 6 and 16 months

Result There was no development of hydrocephalus in this series.

Conclusion Microsurgery fenestration of Lamina Terminalis associated with Liliequist's Membrane fenestration is effective in preventing late hydrocephalus after subarachnoid hemorrhage due to ruptured aneurysm.
