Transsylvian transopercular peri-central core hemispherotomy for treating epilepsy: anatomy, surgical technique, and clinical outcome.
The objective of this study was to display the anatomical landmarks, surgical technique, and clinical outcome of transsylvian transopercular peri-central core hemispherotomy (TTPH) for treating refractory epilepsy. ⋯ TTPH offers anatomical landmarks as intraoperative guides and has achieved good seizure control and low complication rates.

Timing, type, and impact of thromboembolic events caused by flow diversion: a 10-year experience.
Thromboembolic (TE) events are among the most feared complications after flow diversion (FD) and have been reported to occur even with adequate dual antiplatelet therapy. Herein, the authors characterize thrombotic and embolic events that developed after FD, focusing on the morbidity of each of these events and the predisposing factors associated with their development. ⋯ TE events after FD result from multiple factors, including age, aneurysm characteristics, aneurysm location, antiplatelet resistance, and procedural factors. In our cohort, we found the highest morbidity for patients with TE events presenting with large-vessel occlusion at the middle cerebral artery, and vertebrobasilar system.

Patient height and American Society of Anesthesiologists class as significant risk factors for posterior fossa surgery in the semisitting position.
To optimize surgical positioning for posterior fossa surgery (PFS) using the semisitting position (SSP) to avoid venous air embolism (VAE) and its possible life-threatening consequences, the authors evaluated their experiences with the SSP by analyzing a large cohort of PFS patients. ⋯ In summary, the data demonstrate that SSP can be used safely for PFS when taking special care to optimize positioning in tall and lower-grade ASA patients intraoperatively.

Cognitive outcome after stereo-electroencephalography-guided radiofrequency thermocoagulation in temporal lobe epilepsy.
Stereo-electroencephalography (SEEG)-guided radiofrequency thermocoagulation (RFTC) is being used incrementally in the invasive diagnosis of epilepsy. There is currently a lack of information regarding the potential cognitive consequences of the extended use of this technique. This work describes, for the first time, the cognitive outcomes after RFTC in patients with temporal lobe epilepsy (TLE), evaluated longitudinally and using a control group. ⋯ In the group-level comparisons, discernible cognitive impairment following RFTC was not evidenced. The majority of patients did not exhibit significant individual declines during the 1-year follow-up period. Notably, the procedural intervention yielded no substantial repercussions on memory functioning following hippocampal RFTC. These findings underscore the evidence supporting the cognitive preservation associated with SEEG-guided RFTC.

Awake versus asleep deep brain stimulation for Parkinson's disease: a comprehensive systematic review and meta-analysis.
Deep brain stimulation (DBS) has become an effective and safe treatment in patients with Parkinson's disease (PD) not responding to conventional treatments. With the growing body of literature regarding the use of DBS in different movement disorders, there remain controversies regarding performing awake or asleep DBS. This systematic review provides the most comprehensive review of the literature comparing the two techniques from various aspects in detail. ⋯ These findings suggest comparable clinical outcomes between the two DBS approaches. The two methods had their salient differences in terms of lead passes and specific adverse events. The decision to perform awake or asleep DBS should be based on the patient's preference, the surgeon's experience, the availability of advanced intraoperative imaging, and the patient's tolerance for specific adverse events.
