[Surgical treatment of cortical and subcortical cavernomas. General principles and personal series of 20 cases treated between 2000 and 2006]. / Traitement chirurgical des cavernomes corticaux et sous-corticaux. Principes généraux et série personnelle de 20 cas opérés entre 2000 et 2006.

ABSTRACT

The surgical treatment of cortical or subcortical hemispheric cavernomas is founded on a series of questions Is the cavernoma located in an eloquent or non-eloquent area? Is the cavernoma tangent to the cortex and visible immediately after the dura opening or deep seated in the hemisphere? Does the cavernoma lie in the depth of a sulcus and identifiable on the pretrans-sulcal approach MRI? Will perilesional tissue have to be removed to cure the epilepsy? What is the appropriate technology for each particular case preoperative functional MRI, angiography, preoperative stereotactic guidance, peroperative ultrasonography, neuronavigation, peroperative neurophysiology and cortical stimulation, preoperative MRI? Based on a personal series of 20 cases operated on between 2000 and 2006, we describe our personal experience.
