Patient-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.

Survival 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.

Stereotactic radiosurgery for noncavernous sinus dural arteriovenous fistulas: treatment outcomes and their predictors.
Stereotactic radiosurgery (SRS) has emerged as a safe and effective treatment modality for dural arteriovenous fistulas (dAVFs), particularly cavernous sinus (CS) dAVFs. However, the long-term outcomes of non-CS dAVFs are not well known. This study aimed to evaluate the efficacy and safety of SRS for non-CS dAVFs and to investigate the risk factors for incomplete obliteration. ⋯ SRS for non-CS dAVFs is safe, and its efficacy is highly variable according to location. High-flow shunts may indicate greater radioresistance. In the retreated cases, new fistulas tended to be accompanied by sinus steno-occlusion and formed in the adjacent sinus segments.

Association of carotid endarterectomy at low-volume centers with higher likelihood of major complications and nonroutine discharge.
Carotid artery stenosis (CAS) is associated with an annual stroke risk of 2%-5%, and revascularization with carotid endarterectomy (CEA) can reduce this risk. While studies have demonstrated that hospital CEA volume is associated with mortality and myocardial infarction, CEA volume cutoffs in studies are relatively arbitrary, and no specific analyses on broad complications and discharge disposition have been performed. In this study, the authors systematically set out to identify a cutoff at which CEA procedural volume was significantly associated with major complications and nonroutine discharge. ⋯ CEA patients, asymptomatic or symptomatic, are at a higher risk of major complications and nonroutine discharge at low-volume centers. Analysis of CEA as a continuous variable demonstrated a cutoff at 7 cases per year, and further study may identify factors associated with improved outcome at the lowest-volume centers.
