title: [Results of surgical treatment].
abstract: In this chapter we report the results of the main papers of the international literature, but it is difficult to make an objective synopsis because only the best results are published and failure and complications remain confidential. Few papers describe "general complications" as thrombo phlebitis, wound infection, cardio respiratory insufficiency... which are probably as frequent as for all intracranial or spinal surgical procedures. The postoperative neurological status depends essentially on the location of the lesion. In non eloquent area, the postoperative neurological status is almost always excellent. But in a hemispheric functional area, basal ganglia and brain stem it is frequent to observe neurological sequellae; in the better series of the literature, 80% of the patients achieve a good outcome equivalent to or better than before the operation, but 20% are worsened. It is important to remember this fact before discussing the surgical indication. The risk of hemorrhage disappears after total surgical resection; and it is one of the benefits of the treatment, but this objective can be reached only when the lesion is unique. The risk persists in multiple forms and "de novo" cavernomas are always possible especially in familial forms. The main benefit is the treatment of epilepsy for seizure control. In case of good concordance between the location of the cavernoma and the clinical and electrical data, lesionectomy alone or lesionectomy with resection of the perilesional hemosiderin ring provide good results. In the event of severe epilepsy without good concordance between the site of the cavernoma and symptoms, the surgical approach may be functional and outcome less satisfactory.
