Tratamiento quirúrgico de la epilepsia en pacientes con cavernomas. Revisión bibliográfica

Abstract

Cavernous malformation respresents about 5-10% of vascular malformations of brain and spine. Seizure is the most frecuent
clinical manifestation of supratentorial cavernomas, after a first seizure the risk of recurrence is about 94% and 35-40% of
these patients will develop refractory epilepsy. The aim of the present review is to discuss the role of surgery in patients with
early onset seizure and in patients with refractory epilepsy. We also mention pre-surgical considerations in the treatment of
temporal and extra-temporal cavernomas. For surgical planning it is important an accurrate preoperative study as well as
considering location of the lesion and time of evolution of seizure. Surgery offer good outcome, 75% of patientes are seizure
free after surgery, better results are achieved in non refractory patients.
