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.

Although it is generally agreed upon that surgery for high-grade spondylolisthesis (HGS) is associated with more complications than low-grade spondylolisthesis, its description is primarily based on case reports and relatively small case series. ⋯ This study provides short-term complication rates associated with surgical treatment for HGS in adult and pediatric patients and may prove valuable for patient counseling, surgical planning, and in efforts to improve the safety of patient care.

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.

Inferior petrosal sinus sampling (IPSS) is a useful technique for confirming a pituitary source of adrenocorticotropic hormone (ACTH) overproduction in Cushing disease. Uncertainty remains regarding the appropriate course of therapy when an ectopic tumor is predicted by IPSS but none can be found and in circumstances when the procedure cannot be successfully completed owing to technical or anatomic limitations. ⋯ Transsphenoidal surgery should be considered in cases of ACTH-dependent Cushing disease and noncentralized or technically unsuccessful IPSS without evidence of ectopic tumor.
