Interactive Image-Guided Surgery Using an Infrared-Based System
The surgical management of intracranial tumors has always been a challenge for the neurosurgeon, from the dual perspective of acquiring a complete resection on one hand and maintaining neurological function on the other. Stereotactic technology followed by computer-assisted neuronavigation has markedly changed the outcome of these operations. It has improved the accuracy of resection, diminished the neurological complication rate, and decreased the length of hospital stay and costs. Interactive image-guided surgery has extended its applications to other fields such as epilepsy and skull-base and spine surgery, and is even used in brain trauma. From December 1991 to December 1996, we used an infrared-based system for intraoperative image-guided resections; in 1995 we began using the same system for spinal applications as well. Our patient group includes 464 patients treated for intracranial pathology and 27 for spinal lesions. In this chapter we discuss our system, protocols used for different applications, and preliminary results in patient care. From our experience with this system we conclude that the infrared-based neuro-navigator is a very useful technology that increases accuracy and the safety of surgical resection.
