SANCHEZ GONZALEZ, Federico et al. Planeamiento neuroquirúrgico informático: resultados con su utilización. Rev. argent. neurocir. [online]. 2009, vol.23, n.1, pp.9-14. ISSN 1850-1532.

Objective: To describe the results obtained with the method of computerized neurosurgical planning in a group of patients with intracranial pathology. Method: 10 patients (7 men and 3 women, median age 60,2 years) presenting intracranial lesions (1 abscess, 5 intra-axial and 4 extra-axial tumors) were operated on. Images of CT and/ or MRI in DICOM format were obtained before each surgery. They were processed with a software (MRIcro V1.40) generating three-dimensional reconstructions of the head of the patients. Intracranial regions of interest were defined, projecting them towards the surface. A photograph of the patient and the 3D reconstruction were then merged, allowing us to plan the most indicated site for the incision and craniotomy. In the cases without cortical expression, the planning was made with this technique combined with stereotaxis. Results: In all the cases, the incisions and craniotomies were adequate to reach the surgical targets. When comparing this method with the stereotactic, coincidence was observed in the planning of the approach. All the patients evolved without new or added postoperative neurological deficit. Conclusion: the computerized neurosurgical planning allowed an adequate location of the intracranial lesions in a simple way, and with a low cost.
