ns when performing surgical, endovascular, and radiosurgical procedures, covering the full range of indications and potential adverse events. All chapters have a standardized format, simplifying the search for information on a specific disease process. Numerous intraoperative images are included, and, when appropriate, algorithms for the avoidance, early recognition, and management of complications are presented. Each chapter concludes with a checklist of preparatory steps and "emergency procedures" that each member of the team must perform in order to ensure the best possible outcomes.
