Case Reports WebcastsHead-up display may facilitate safe keyhole surgery for cerebral aneurysm clipping.
The head-up display (HUD) is a modern technology that projects images or numeric information directly into the observer's sight line. Surgeons will no longer need to look away from the surgical view using the HUD system to confirm the preoperative or navigation image. The present study investigated the usefulness of the HUD system for performing cerebral aneurysm clipping surgeries. ⋯ The HUD images superimposed on the microscope field of view were remarkably useful for less invasive and more safe aneurysm clipping and, in particular, keyhole clipping.

Neuronavigation systems are routinely used during neurosurgical procedures. Currently, new imaging technologies are emerging, such as virtual, augmented, and mixed reality. With mixed-reality devices, the user can analyze and interact with the real environment using virtual objects. The aim of this prospective pilot study was to offer a proof of concept by testing the clinical feasibility and accuracy of a wearable mixed-reality device (Hololens) for preoperative neurosurgical planning. ⋯ This prospective clinical study offers a proof of concept of the clinical feasibility of the Hololens for brain tumor surgery planning in the operating room, with quantitative outcome measures. Further development is needed to improve the accuracy of this wearable mixed-reality device.

To investigate how frameless navigational techniques can be implemented to support standard frame-based stereotactic procedures. ⋯ In a setting with intraoperative imaging, the combination of frameless and frame-based techniques offers new possibilities. Because of the high registration accuracy, the additional navigation provides improved safety and redundancy. Furthermore, the stereotactic procedure is supported by enhanced intuitive intraoperative visualization during the advancement of a biopsy needle or electrode. However, further technical refinements are necessary, such as possibilities to track microelectrodes during the advancement with a microdrive.

To investigate the clinical efficacy of navigation-guided minimally invasive surgery in patients with hypertensive basal ganglia hemorrhage. ⋯ Under certain conditions, compared with standard craniotomy and hematoma evacuation, navigation-guided hematoma puncture aspiration and catheter drainage is simple, effective, and safe as a treatment for hypertensive basal ganglia hemorrhage.

An intraoperative motor tract positioning method in brain tumor surgery: technical note.
Intraoperative 3D recognition of the motor tract is indispensable to avoiding neural fiber injury in brain tumor surgery. However, precise localization of the tracts is sometimes difficult with conventional mapping methods. Thus, the authors developed a novel brain mapping method that enables the 3D recognition of the motor tract for intrinsic brain tumor surgeries. ⋯ Safe tumor resection with an arbitrary safety margin can be performed by adjusting the length of the plastic tubes. The motor tract positioning method enabled the 3D recognition of the motor tract by surgeons and provided for safe resection of tumors. Tumor resections were performed safely before damaging motor tracts, without any postoperative neurological deterioration.
