Stereo-electroencephalography pattern and long-term seizure outcome in hypothalamic hamartoma treated by radiofrequency thermocoagulation.
The aim of this study was to investigate the long-term outcomes and clinical predictors for seizure freedom in patients with hypothalamic hamartomas (HHs) undergoing radiofrequency thermocoagulation (RFTC) guided by stereo-electroencephalography (SEEG). ⋯ The SEEG signal can guide HH ablation and serve as an important predictor for favorable seizure outcomes in both the short term and long term, a capability not exhibited by other factors thus far. Patients with a history of HH resection but who still experience NGSs should be considered carefully, as there may be a speculated mechanism of an NGS network re-forming, which can partly explain the outcome difference between patients with GSs and those with NGSs, as well as the progression of secondary epileptogenesis.

Outcomes following stereotactic radiosurgery for high-grade brain arteriovenous malformations: a systematic review and meta-analysis.
Arteriovenous malformations (AVMs) of the brain are a leading cause of stroke in the young and carry a lifetime risk of intracerebral hemorrhage. The management options for high-grade AVMs are limited. Resection is often associated with high rates of postoperative morbidity, and the results of stereotactic radiosurgery (SRS) for these lesions thus far have been mixed. The aim of this study was to summate the published data on the outcomes of SRS for high-grade AVMs in order to better inform the management of these otherwise untreatable lesions. ⋯ SRS for high-grade AVMs is associated with a modest rate of obliteration and is complicated by AREs in 9% of cases. Patients harboring previously ruptured AVMs or lesions with high-risk angioarchitectural features may be more likely to benefit from this treatment.

The influence of prestroke disability on outcome in patients with a low Alberta Stroke Program Early CT Score who underwent endovascular thrombectomy.
The definitive influence of prestroke disability on outcomes in patients with a low Alberta Stroke Program Early CT Score (ASPECTS) treated with endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO) remains unknown. This study aimed to investigate the impact of prestroke disability on outcomes in this specific population. ⋯ The present study indicated that prestroke disability was not associated with a return to the prestroke mRS score at 90 days or intracranial hemorrhage. Physicians should not routinely exclude AIS-LVO patients with a low ASPECTS who have prestroke disability from EVT based on prestroke disability alone.

Effects of the length of preoperative conservative management on postoperative outcomes after primary microvascular decompression for trigeminal neuralgia.
Although trigeminal neuralgia (TN) is initially managed conservatively, approximately half of all patients will eventually undergo surgery. Despite this outcome, there is limited understanding of the relationship between preoperative length of conservative management and pain outcomes after microvascular decompression (MVD). In this study, the authors aimed to describe the relationship between the duration of preoperative conservative management and postoperative outcomes in patients undergoing MVD for TN. ⋯ In the setting of primary MVD for patients with TN, a longer duration of preoperative conservative management was associated with higher postoperative BNI pain scores and increased risk of pain recurrence. These findings suggest a potential beneficial role for early surgical intervention.
