Abstract

Image-guided stereotaxis is an accurate and safe method of directing therapy to target volumes defined in 2D multi-planes or 3D perspectives using computer reconstruction of image data. The major limitations of stereotactic techniques are the lack of intraoperative visualization and the ability to directly monitor the procedures, and changes of intracranial coordinates after decompression of cystic lesions or aspiration of cerebrospinal fluid in the management of intraventricular lesions. Stereotactic neuroendoscopy involves integration of rigid-flexible endoscopy and the Nd-YAG laser in 2D/3D multiplanar image-guided stereotactic procedures. The major advantages of endoscopic laser surgery include being minimally invasive (burrhole or small craniotomy surgery), direct intraoperative visualization, hemostasis, evacuation or resection assessment, and wide exploration of intracranial cavities or ventricles. We used endoscopic laser surgery in the management of 202 patients undergoing biopsy, aspiration, resection, and internal decompression of deep and subcortical intracranial lesions, and for different types of fenestration procedures. Image-guidance combined with endoscopic techniques may offer a safe, accurate alternative to conventional neurosurgical procedures in treating small solid, cystic, intraventricular lesions, and in fenestration procedures.
