Computed Tomography-Guided Thalamotomy

Conference paper


Recent development of computed tomography (CT)-guided stereotaxis has opened a new era in functional stereotactic surgery. Until recently, contrast-medium enhanced ventriculography only gave information of the internal boundaries of the third ventricle, but nothing could be seen of the posterior and lateral extensions of the thalamus. Additionally, ventriculography could cause a dilatation and displacement of the third ventricle. The headaches and nausea increased the surgical risks of thalamotomy. With CT it is possible to define the posterior (cisterna ambiens) and lateral (internal capsule) margins of the thalamus and thus increase the chances of proper positioning of the therapeutic lesions.
