Image-guided Stereotactic Neurosurgery: Practices and Pitfalls

Endoscopic and stereotactic neurosurgery.

PURPOSE OF REVIEW Review of the anesthetic considerations for neuroendoscopy and stereotactic procedures. RECENT FINDINGS Minimally invasive procedures are increasingly applied in novel ways in the diagnosis and treatment of neurological pathologies. Endoscopic third ventriculostomy, endoscopic shunt revisions and drainage of intraventricular hematoma using a neuroendoscope have become routin...

3D Laser Scanning for Image-Guided Neurosurgery

This paper describes on-going work by the Environmental Research Institute of Michigan (ERIM) and The University of Michigan Medical Center to develop a new approach to frameless stereotsxy, in which patient-image registration is accomplished using a 3D laser imaging sensor and precaptured CT scans. Alternative methods under development for frameless stereotactic neurosurgery are reviewed and c...

Distance sonification in image-guided neurosurgery

Image-guided neurosurgery, or neuronavigation, has been used to visualise the location of a surgical probe by mapping the probe location to pre-operative models of a patient's anatomy. One common limitation of this approach is that it requires the surgeon to divert their attention away from the patient and towards the neuronavigation system. In order to improve this type of application, the aut...

CT-guided stereotactic neurosurgery: experience in 24 cases with a new stereotactic system.

Twenty-four cases have been operated upon using a prototype Brown-Roberts-Wells, CT-guided stereotactic neurosurgical system. This device has proved to be practical and flexible in clinical use. No CT scanner modifications were required, a fact which simplified its use in more than one hospital. Multiple targets can be biopsied with ease and relative safety. Drainage and other therapeutic proce...
