There has been controversy regarding the management of syringomyelia associated with tethered spinal cord. Previous reports on the topic have included only a small number of patients, considered open/closed spinal dysraphism together, or had a short follow-up. ⋯ Untethering alone may be sufficient for the management of syringomyelia associated with tethered cord. A transient increase in the syrinx index during the initial postoperative period may be observed without additional surgery if patients are symptomatically stable.

The SAMMPRIS (Stenting vs Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis) trial, comparing aggressive medical vs stent treatment in patients with symptomatic intracranial stenosis, was halted after a 14% stroke and death rate was observed in the stent-treated group. ⋯ The overall 30-day postprocedure stroke and death rate in our study was lower in both SAMMPRIS-eligible and -ineligible groups than the reported 14% stroke and death rate in the SAMMPRIS trial. We hypothesize that a more judicious use of primary angioplasty may be responsible for better postprocedure outcomes and should be considered an acceptable treatment in future trials.

Lead migration is a significant concern with spinal cord stimulator (SCS) placement with rates ranging from 10% to 60%. ⋯ We present a novel technique in the hopes of decreasing the incidence of lead migration after minimally invasive placement of spinal cord stimulator laminectomy paddle leads. Our results have been promising thus far with no cases of lead migration.

The Rotterdam computed tomography (CT) score was developed for prognostic purposes in traumatic brain injury (TBI). ⋯ For head-injured patients undergoing DC, the Rotterdam CT score provides great prognostic discrimination and is an independent predictor of unfavorable outcomes. We suggest that the Rotterdam CT score be included as a prognosticator in the overall assessment of clinical condition of TBI patients before DC.

Subdural hematoma (SDH) in patients with cancer is poorly described, and its frequency and causes may have changed with recent oncologic advances. ⋯ Leukemia and prostate cancer are the most common systemic cancers associated with SDH, and gliomas may predispose to SDH more often than previously recognized. Coagulopathy is common and associated with the worst outcome, but many patients experience good functional outcome and survival.
