Noninvasive evaluation of the glymphatic system in diffuse gliomas using diffusion tensor image analysis along the perivascular space.
The aim of this study was to noninvasively explore the glymphatic system (GS) in glioma and its association with glioma characteristics and prognosis by using diffusion tensor image analysis along the perivascular space (ALPS). ⋯ GS function was impaired in glioma and correlated with tumor characteristics, and worse contralateral GS function was associated with a shorter survival time.

Multicenter Study Comparative StudyDecompressive craniectomy in symptomatic intracerebral hemorrhage after ischemic stroke: a multicenter retrospective cohort study.
Symptomatic intracerebral hemorrhage (sICH) after stroke is a devastating neurological complication. Current guidelines support a "possible benefit" of decompressive craniectomy (DC) for large supratentorial sICH with significant mass effect. ⋯ DC after sICH did not improve functional outcome at 90 days according to multivariable analysis, although younger age and absence of previous cancer history were associated with improved outcomes.

Randomized Controlled Trial Multicenter StudyREACT: a randomized trial to assess the efficacy and safety of clazosentan for preventing clinical deterioration due to delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.
Ischemic complications account for significant patient morbidity following aneurysmal subarachnoid hemorrhage (aSAH). The Prevention and Treatment of Vasospasm with Clazosentan (REACT) study was designed to assess the safety and efficacy of clazosentan, an endothelin receptor antagonist, in preventing clinical deterioration due to delayed cerebral ischemia (DCI) in patients with aSAH. ⋯ Clazosentan administered for up to 14 days at 15 mg/hour had no significant effect on the occurrence of clinical deterioration due to DCI. Clinical trial registration no.: NCT03585270 (ClinicalTrials.gov) EU clinical trial registration no.: 2018-000241-39 (clinicaltrialsregister.eu).

Meta AnalysisAnterior choroidal artery aneurysms: a systematic review and meta-analysis of outcomes and ischemic complications following surgical and endovascular treatment.
Anterior choroidal artery (AChA) aneurysms account for 2%-5% of all intracranial aneurysms. Treatment considerations include microsurgical clipping, flow diversion, or coiling with or without adjunctive devices. AChA aneurysms pose challenges in treatment due to the origination of the aneurysm from the origin or proximal segment of the AChA. The AChA is particularly susceptible to vasospasm and occlusion during treatment with devastating neurological deficits, including hemiparesis, hemianesthesia, lethargy, neglect, and hemianopia. In this study, the authors performed a meta-analysis to quantify the outcomes and complication rates across treatment modalities for AChA aneurysms and to identify risk factors reported in the literature. ⋯ Flow diversion showed significantly lower total and ischemic complications and improved outcomes compared to clipping and coiling. There may be differences in outcomes between treatment types, especially when considering the varied patient presentations that guide treatment selection.

Comparative StudyPipeline embolization device placement under local versus general anesthesia: a propensity score-matched study.
Pipeline embolization device (PED) placement for the treatment of intracranial aneurysms is safe and effective under general anesthesia (GA). However, GA is associated with certain risks, longer procedural time, and higher hospital cost. The authors aimed to compare clinical outcomes and hospital cost between GA and local anesthesia (LA) procedures in patients who underwent PED placement for intracranial aneurysm treatment. ⋯ PED placement under LA can achieve satisfactory outcomes similar to those of PED placement under GA; however, the use of LA reduces procedural time and hospital cost.
