Craneotomía para derivación cerebral

Toggle: English / Spanish

Para realizar una derivación cerebral se corta un colgajo en el cuero cabelludo y se taladra un pequeño hueco en el cráneo. Luego se introduce un pequeño catéter dentro del ventrículo cerebral. Se conecta una bomba (válvula que controla el flujo de líquido) al catéter para mantener el líquido alejado del cerebro. La acumulación excesiva de líquido alrededor del cerebro puede ocasionar un aumento en la presión intercraneal. El exceso de presión puede causar una disminución de flujo sanguíneo al cerebro, lo que puede conllevar a daño cerebral.
