Stereotactic radiosurgery (SRS) of larger arteriovenous malformations (AVM) is associated with an elevated incidence of adverse radiation effects (ARE). To date, volume-response and dose-response models have been used to predict such effects. To understand radiological outcomes and their hemodynamic effects on the regional brain. ⋯ Transit times and vessel diameters are valuable predictors of the subsequent parenchymal response after SRS. A more quantitative understanding of blood flow is critical for predicting the effects on the regional brain after AVM radiosurgery.

Multicenter Study
Complications of the Prone Transpsoas Lateral Lumbar Interbody Fusion for Degenerative Lumbar Spine Disease: A Multicenter Study.
The prone transpsoas (PTP) approach for lateral lumbar interbody fusion (LLIF) is a novel technique for degenerative lumbar spine disease. However, there is a paucity of information in the literature on the complications of this procedure, with all published data consisting of small samples. We aimed to report the intraoperative and postoperative complications of PTP in the largest study to date. ⋯ In this multicenter case series, the PTP approach was well tolerated and associated with a satisfactory safety profile.

Although female neurosurgery residents are increasing, women remain underrepresented in academic leadership. ⋯ Without publicly available, self-identified gender designation for each resident, we were limited to review/designate gender based on male-presenting/female-presenting status from gender conventions of names/appearance. Although not an ideal measurement, this helped show that during neurosurgical residency, male residents publish significantly more than female counterparts. Given similar preresidency h- indices and publication records, this is unlikely explained by differences in academic aptitude. In-residency gender barriers to academic productivity must be acknowledged and addressed to improve female representation within academic neurosurgery.

The management of octogenarians with vestibular schwannomas (VS) has received little attention. However, with the increase in octogenarian population, more effort is needed to clarify the value of stereotactic radiosurgery (SRS) in this population. The aim of this study was to evaluate the safety and efficacy of SRS in this patient age group. ⋯ SRS resulted in tumor and symptom control in most octogenarian patients with VS.

Mechanical thrombectomy failure (MTF) occurs in approximately 15% of cases. ⋯ Anterior circulation MTF is associated with more complications and worse outcomes. No differences were found between techniques or devises used for the first pass during MT. Rescue intracranial stenting may decrease the likelihood of MTF for posterior circulation MT.
