Fuga del LCR - Overview

Nombres alternativos

Hipotensión intracraneal

Definición:

La fuga o filtración de LCR (líquido cefalorraquídeo) es un escape del líquido que rodea el cerebro y la médula espinal.

Causas, incidencia y factores de riesgo:

Cualquier ruptura o agujero en la membrana que rodea el cerebro y la médula espinal (duramadre) puede dejar que se escape el líquido que rodea esos órganos.

Este líquido se denomina líquido cefalorraquídeo (LCR). Cuando se escapa hacia afuera, la presión alrededor del cerebro y la médula espinal disminuye.

Las causas de la fuga a través de la duramadre abarcan:

Ciertas cirugías de la cabeza, el cerebro o la columna
Traumatismo craneal
Colocación de sondas para administrar anestesia epidural o analgésicos
Punción raquídea (punción lumbar)

Algunas veces no se puede encontrar ninguna causa. Esto se denomina fuga espontánea de LCR.
