Case Reports
Patients with refractory epilepsy treated using a modified multiple subpial transection technique.
: Multiple subpial transection (MST) is a potential surgical treatment for patients with epileptogenic foci located in cortical areas with higher functions. As neurosurgical teams have become more experienced with MST, the original technique has adapted. ⋯ : BA, Brodmann areaEEG, electroencephalogramFDG, 18-fluorodeoxyglucoseioECoG, intraoperative electrocorticographyMRE, medically refractory epilepsyMST, multiple subpial transectionMSTa, multiple subpial transection aloneMST+, multiple subpial transection with other procedures.

[Application of intraoperative magnetic resonance imaging and multimodal navigation in surgical resection of glioblastoma].
To evaluate the efficacy of intraoperative magnetic resonance imaging (iMRI) and multimodal navigation in surgical resection of glioblastoma. ⋯ Combined with multimodal navigation, iMRI helps maximize surgical resection of glioblastoma, preserving neurological function while increasing progression-free survival and overall survival.

Deep brain stimulation (DBS) requires precise and safe navigation to the chosen target. Optical measurements allow monitoring of gray-white tissue boundaries (total light intensity [TLI]) and microvascular blood flow during stereotactic procedures. ⋯ Laser Doppler is useful for intraoperative guidance during DBS implantation because simultaneous measurement of tissue grayness and microvascular blood flow can be done along the trajectory with millimeter precision. Typical but different TLI trajectories were found for the Vim and STN.

High-field, intraoperative magnetic resonance imaging (iMRI) achieves free tumor margins in glioma surgery by involving anatomic neuronavigation and sophisticated functional imaging. ⋯ Perfusion-weighted iMRI may be implemented easily into imaging protocols and may assist the surgeon in detecting residual tumor volume.
