In this article, we present an overview of the principles, practices and procedures of the presurgical evaluation of the epilepsies in use in our center and in the majority of French teams. Surgery for epilepsy is offered to patients presenting with severe epilepsy with partial seizures. Its aim is to stop the seizures, or to significantly reduce their frequency. ⋯ The phase II is often required and is aimed to precisely define the anatomical localization of the epileptogenic zone and the relationships with a structural lesion. This invasive phase is mainly based on stereoelectroencephalography (SEEG). Finally, the surgical procedure must be adapted according to the distribution and dynamics of the anatomical and functional abnormalities which individually define each case of epilepsy.

Many coagulation disorders have been associated with cerebral venous thrombosis. These disorders may be primary like protein C and S deficiency, antithrombine III deficiency and activated protein C resistance. Antiphospholipid antibodies represent an acquired disorders of coagulation. A prothrombotic state induced by more common factor including oral contraceptive, pregnancy and puerperium increases the venous thrombosis risk.
