Post-craniotomy neuronavigation based purely on intraoperative ultrasound imaging without preoperative neuronavigational planning.
Neuronavigation has become an established technology which provides objective data for localization in 3D space and thus decreases uncertainties regarding tumor localization, relation to vasculature, safe trajectories, and craniotomy design during surgery. We have evaluated whether neuronavigation based purely on 3D ultrasound without any preoperative navigational imaging can provide necessary information for navigation and resection control. This application is a new way of utilizing ultrasound-guided neuronavigation. ⋯ The two biopsies yielded representative material. It was possible to use operative neuronavigation based on intraoperative ultrasound without relying on preoperative navigational imaging. Neuronavigation based solely on intraoperative ultrasound was feasible and may increase surgical safety when preoperative neuronavigational image is not feasible or unavailable.
