Defining ideal middle cerebral artery bifurcation aneurysm size for Woven EndoBridge embolization.
The Woven EndoBridge (WEB) device was approved to treat wide-necked bifurcation aneurysms. The device is designed as an intrasaccular flow disruptor covering aneurysm widths up to 10 mm. Although prior studies combined all aneurysm sizes, it is known that aneurysms behave differently in response to endovascular treatment based on their size. Therefore, the authors' objective was to identify ideal middle cerebral artery (MCA) aneurysm width and neck sizes most suitable for WEB treatment. ⋯ This study shows that MCA bifurcation aneurysms ≤ 6.1 mm in width and ≤ 4.6 mm in neck size are significantly better candidates for WEB treatment, leading to improved occlusion status and reduced retreatment rate, which are important considerations when using WEB devices.

Creating and validating a neurosurgical intervention rule-out tool for patients with mild traumatic brain injury and isolated subdural hematoma: a 5-year, six-center retrospective cohort study.
Because there is no reliable method on admission to predict whether a patient will require neurosurgical intervention in the future, the general approach remains to treat each patient with mild traumatic brain injury (mTBI) and subdural hematoma (SDH) as if they will require such an intervention. Consequently, there is a growing population of patients with mTBI and SDH that is overtriaged despite having a low probability of needing neurosurgical intervention. This study aimed to train and validate a predictive rule-out tool for neurosurgical intervention in patients with mTBI and SDH. ⋯ In this study, the largest of its kind to date, the authors successfully developed and validated a new tool for ruling out the necessity of neurosurgical intervention in patients with mTBI and isolated SDH. By successfully identifying more than half of patients who are unlikely to require neurosurgery within the first 2 days of admission, this tool can be used to improve treatment efficiency and provide patients and clinicians with valuable prognostic information.

Rapid response system and outcomes in patients who underwent cranial neurosurgery: a nationwide cohort study.
Hospitals use rapid response systems (RRSs) to identify and treat patients whose conditions rapidly worsen after admission. However, no study has examined the effects of RRS deployment on the clinical outcomes of patients undergoing cranial neurosurgery. Thus, the authors investigated whether use of RRS affects clinical outcomes in these patients. ⋯ This population-based cohort study revealed that implementing RRS was associated with enhanced short- and long-term survival outcomes in patients who underwent cranial neurosurgery. The authors' findings indicate that the introduction of RRS can enhance patient survival rates after cranial neurosurgery.

Frailty and outcomes after unilateral MRI-guided focused ultrasound thalamotomy for tremor.
Frailty is recognized as an important predictor of neurointerventional outcomes. MRI-guided focused ultrasound (MRgFUS) thalamotomy is a treatment option for patients with refractory essential tremor (ET) and tremor-dominant Parkinson's disease (TdPD). The aim of this study was to evaluate whether frailer MRgFUS thalamotomy patients had worse tremor outcomes or more complications. ⋯ Increasing frailty is not associated with worse outcomes, suggesting that MRgFUS may be appropriate even for frailer patients. ET patients are frailer than TdPD patients selected for MRgFUS.

Effect of pituitary stalk preservation during craniopharyngioma removal on pituitary function, extent of resection, and recurrence: systematic review and meta-analysis.
Optimal management of the pituitary stalk during craniopharyngioma resection remains a controversial subject. This meta-analysis aimed to evaluate the effect of pituitary stalk preservation on postoperative diabetes insipidus (DI), anterior pituitary function (PF), extent of resection, and recurrence. ⋯ Pituitary stalk preservation was demonstrated to confer protective benefit on PF, although the benefit persisted on long-term follow-up for posterior PF only. Stalk preservation in pediatric patients should be given careful consideration, as it is associated with higher rates of incomplete resection. These results should be interpreted with caution due to inclusion of small studies and inadequate reporting of outcomes in the literature.
