Technical aspects of SEEG limitations and solutions using the Leksell Vantage frame.

ABSTRACT:

Background

Stereo-electroencephalography (SEEG) is an invasive electroencephalography method to precisely locate a seizure onset zone (SOZ). While today´s armamentarium allows any compromise between the historically strict orthogonal and oblique trajectories, the following aspects limit its effectiveness and safety. The shorter the distance from entry to the brain and target the less deviation of the electrode. The closer to orthogonal to the scull the more stable the anchor sits in the scull and deviation can be better controlled. Beyond that, limitations due to the stereotactic frame must be considered. In certain cases, a conflict between frame setup and entry point of the trajectory can arise. This conflict spurred us to explore the limits of stereotactic frame and the associat
