The coronavirus disease-19 (COVID) pandemic has presented a significant challenge to health care providers. Neurosurgical patients are often critically ill and at particularly high risk for COVID, and the pandemic has produced ever-shifting circumstances to allow their continued care. This study explores the psychologic impact of the pandemic on neurosurgical residents at a single institution. ⋯ There were no significant changes in perceived stress or depressive symptoms among neurosurgical residents during the pandemic.

Clinical and/or neuroimaging changes after whole-brain radiation therapy (WBRT) or stereotactic radiosurgery (SRS) for metastatic brain tumor(s) present the clinical dilemma of differentiating tumor recurrence from radiation necrosis. Several imaging modalities attempt to answer this clinical question, including magnetic resonance spectroscopy (MRS) and positron emission tomography (PET) computed tomography (CT). We evaluated our experience regarding the ability of MRS and PET CT to differentiate tumor recurrence from radiation necrosis in patients who have received WBRT or SRS. ⋯ MRS has better accuracy than PET CT and a high negative predictive value, therefore making it more useful in distinguishing recurrent tumor from radiation necrosis. We encourage correlation with symptoms at imaging to aid in clinical decision making.

Venous stenting (VS) for venous sinus stenosis in the setting of idiopathic intracranial hypertension has been increasing in acceptance by neurointerventionalists. Stent-adjacent stenosis (SAS) and in-stent stenosis leading to symptom recurrence and the need for retreatment are known delayed complications. However, the effect of the dual antiplatelet therapy (DAPT) duration on these complications has remained poorly characterized. ⋯ We found no differences between 3 and ≥6 months of DAPT in terms of the risk of stent stenosis or stent survival. However, patients with a higher venous pressure gradient before VS had a greater risk of stent failure.

To report our experience using the scan-and-plan workflow and review current literature on surgical efficiency, safety, and accuracy of next-generation robot-assisted (RA) spine surgery. ⋯ The scan-and-plan workflow allowed for a high degree of accuracy. It was a safe method that provided a smooth and efficient OR workflow without registration errors or robotic failures. After the placement of 4 pedicle screws, the per-screw time remained constant. Further studies regarding efficiency and utility in multilevel procedures are necessary.
