Background: Neuroendovascular treatment of cerebral aneurysms is considered a basic procedure for neurosurgeons and interventional neuroradiologists; however, its critical technical nuances, termed "tacit knowledge," are challenging to impart. This study aimed to evaluate the efficacy of our novel video recording and editing method in enhancing trainees' experience.
Methods: A wearable camera (wearable recording) and multiple media sources in a hybrid operating room (hybrid recording) were used to capture procedural details such as audio and conversation, thus enabling a re-experience.
Recent technologic advancements have facilitated the use of hypofractionated Gamma Knife-based radiosurgery (HF-GKRS) to treat large lesions or those in eloquent areas. This study aimed to analyze the preliminary results of HF-GKRS for these meningiomas, and to determine its effectiveness and safety. This single-center retrospective study analyzed data of patients who underwent HF-GKRS for large meningiomas or those in eloquent areas with > 6 months of follow-up.

- * In a study of 569 patients treated with SRS, only one case of RIM (gliosarcoma) was found, leading to a very low overall incidence rate of 0.12 per 1,000 patient-years over a long follow-up period (average of 12.5 years).
- * A systematic review of 14 studies indicated RIM incidence rates between 0.00% and 0.24%, with glioblastoma being
Article Synopsis
- The study evaluated how age impacts patient outcomes in those undergoing microsurgical clipping for WFNS grade I/II aneurysmal subarachnoid hemorrhage (SAH), analyzing data from 176 patients over a decade.
- Results indicated that younger patients (≤70 years) had significantly better outcomes (84%) compared to older patients (>70 years) who had only a 46% favorable outcome, making age a crucial prognostic factor.
- The researchers developed a prognostic model based on age and surgical complications, suggesting that tailored postoperative care, especially for older patients, can improve outcomes, highlighting age as a more significant factor than initial WFNS grading in these cases.
Article Synopsis
- Fibrous dysplasia (FD) is mostly symptomless but can lead to rare neurological issues, like abducens nerve palsy, particularly in older patients.
- A case was reported involving a 76-year-old woman who developed left abducens nerve palsy due to pressure from an FD-related cyst, which was successfully treated through endoscopic surgery.
- The case highlights that while FD usually affects younger individuals, it can cause serious complications such as nerve palsy in older patients, especially when cysts form and create pressure that necessitates surgical intervention.
