Abstract

CENTENO, Ricardo Silva et al. Stereoelectroencephalography in the era of imaging guide surgery. J. epilepsy clin. neurophysiol. [online]. 2009, vol.15, n.4, pp.178-183. ISSN 1676-2649.  http://dx.doi.org/10.1590/S1676-26492009000400008.

INTRODUCTION: The stereoelectroencephalography (SEEG), introduced by Talairach in 50', is an invasive method of tridimensional analysis of epileptogenic zone based on the intracranial placement of depth electrodes (DE). The advent of modern imaging guided surgery had a tremendous impact in DE implantation techniques. OBJETIVE: The aim of this article is to discuss the main principles of SEEG and its evolution along the years since Talairach era until the imaging guide surgery era, with its new perspectives. CONCLUSIONS: Although the main principles of SEEG have remained intact, the placement of depth electrodes (DE) which is the surgical technique that supports this method has suffered a tremendous evolution along the last three decades due the advent of the modern imaging, the computer systems and the new stereotactic techniques. The use of robotic, the new imaging and computed systems and the use of probes of micro dialise adaptated to EP opened a tremendous perspective to DE and SEEG application as an investigative and therapeutical method. The discovery of new targets in deep brain localization and the manufacturing of "smart" DE, can increment, in a near future, the number of indications to this method.
