ReviewPatient-reported outcome measures in cerebrovascular neurosurgery.
The object of this study was to describe the use of patient-reported outcome measures (PROMs) in cerebrovascular neurosurgery and to outline a framework for incorporating them into future cerebrovascular research. ⋯ There are only a limited number of disease-specific PROMs available for cerebrovascular pathologies and outcomes. Further validation of existing measures in independent cohorts, expanded incorporation of disease-specific PROMs in prospective trials, and the development of new PROMs specific to cerebrovascular conditions are critical to a better understanding of the impact of cerebrovascular diseases and novel therapies on patient lives.

Meta AnalysisSurvival outcomes of intracranial extraventricular neurocytomas: a systematic review and individual patient data meta-analysis.
The rarity of intracranial extraventricular neurocytomas (EVNs) has precluded accurate definition of its surgical characteristics to date. The authors present the first survival analysis of this unique entity that aims to clarify tumor characteristics, surgical outcomes, and efficacy of postoperative adjuvant therapy. ⋯ Intracranial EVNs are rare tumors that portend a poorer prognosis than central neurocytomas, despite both being WHO grade 2 tumors. Complete surgical extirpation is the cornerstone of management. There is no clearly established role for adjuvant postoperative therapy, but each case should be managed on an individual basis.

Focal brain oxygen, blood flow, and intracranial pressure measurements in relation to optimal cerebral perfusion pressure.
Different paradigms for neurocritical care of traumatic brain injury (TBI) have emerged in conjunction with advanced neuromonitoring technologies and derived metrics. The priority for optimizing these metrics is not currently clear. The goal of this study was to determine whether achieving cerebral perfusion pressure (CPPopt) also improves other metrics like brain oxygenation and brain blood flow. ⋯ Although CPPopt was not targeted in the patients in this study, CPPopt was a physiologically significant value based on concurrent measurements of PbtO2 and blood flow. In summative data, achievement of CPPopt was associated with optimized PbtO2 and blood flow. Conversely, the correlation between achievement of CPPopt and the mean measurement value was not strong, strengthening the significance of CPPopt. In individual patients, achieving CPPopt is not always associated with optimal PbtO2 or blood flow. Further research should explore these relationships in treatment paradigms that specifically target CPPopt. These data do not support the premise that targeting and achieving CPPopt obviates the need for concurrent PbtO2 and blood flow monitoring. Although these data suggest that targeting CPPopt may be an appropriate initial treatment strategy, they do not provide evidence that CPPopt should be targeted with highest priority.
