Abstract:

The linking of digitizing pointers to computer programs that reformat diagnostic studies has resulted in the development of image-guided surgery, also called frameless stereotactic surgery. With frameless stereotaxy, the neurosurgeon transposes the three-dimensional physical space of the patient's skull and cranial contents in the operating room with the three-dimensional image space of preoperative computerized tomography (CT) or magnetic resonance imaging (MRI) scans shown in the computer.

Abstract:

The following paper discusses a number of issues relevant to the use of topical hemostatic agents in neurosurgical procedures. We initially describe the basic application of such products and review their relative benefits in neurosurgical interventions, emphasizing the use of oxidized, regenerated cellulose. We then discuss their role in specific operations, such as cortical debridement, cavernous sinus, and other skull base approaches, and aneurysms and arteriovenous malformations of the brain.
