Stroke is a devastating complication after intracranial aneurysm clipping. Understanding the risk factors that prognosticate perioperative stroke may help to identify patients that would benefit from neuroprotective therapy. This study assesses patient-specific independent predictors of perioperative stroke in relation to surgical aneurysm clipping. ⋯ In the absence of aneurysm rupture, patients presenting with new-onset stroke were more likely to suffer postoperative complications, stay in the intensive care unit longer, and be discharged to in-patient rehabilitation compared to patients without new-onset stroke. This study suggests that severity of subarachnoid hemorrhage based on the patient's clinical condition increases the risk of perioperative stroke in patients with surgical aneurysm clipping. SSEP changes and high-grade H/H scores can serve as independent predictors of perioperative stroke, with the latter having the greatest predictive value.

Meningiomas are the commonest type of primary brain tumours. Whilst most patients are seizure-free prior to surgery, antiepileptic drugs are frequently administered to reduce the risk of developing post-operative seizures. However, evidence to support their efficacy in providing this outcome is sparse. ⋯ Based on the results of this systematic review, the routine use of antiepileptic drugs for seizure prophylaxis in seizure-naïve patients undergoing meningioma resection could not be substantiated. However, limitations of a systematic review should be considered on interpretation. High quality prospective randomised controlled trials are required to definitively answer this important clinical question.

Comparative Study
A matched cohort comparison of cervical disc arthroplasty versus anterior cervical discectomy and fusion: Evaluating perioperative outcomes.
Cervical disc arthroplasty (CDA) is a recent alternative to anterior cervical discectomy and fusion (ACDF) in patients suffering cervical disc herniation and degeneration. To date, a systematic analysis of their comparative advantages and risks following elective surgery remains elusive. ⋯ In a matched cohort analysis, CDA performs comparably to ACDF and is associated with decreased operation time and HLOS, and increased likelihood of discharge to home, without differences in 30-day complications or reoperation rates. Future prospective studies are warranted.

Reversible cerebral vasoconstriction syndrome (RCVS) combined with posterior reversible encephalopathy syndrome (PRES) is a rare complication in patients treated with immunosuppressants. A 52-year-old male patient presented with seizures after heart transplantation. ⋯ Digital subtraction angiography (DSA) revealed the classic "sausage on a string" appearance of the cerebral arteries - potential feature of RCVS. To our knowledge, this is the first case report to describe RCVS combined with PRES after heart transplantation.

Randomized Controlled Trial Comparative Study
Comparison of 20% mannitol and 3% hypertonic saline on intracranial pressure and systemic hemodynamics.
Mannitol and hypertonic saline (HS) are most commonly used hyperosmotic agents for intraoperative brain relaxation. We compared the changes in ICP and systemic hemodynamics after infusion of equiosmolar solutions of both agents in patients undergoing craniotomy for supratentorial tumors. Forty enrolled adults underwent a standard anesthetic induction. ⋯ Urine output was significantly higher with mannitol. The perioperative complications, overall hospital stay, and Glasgow outcome score at discharge were comparable in between the two groups. To conclude, both mannitol and hypertonic saline in equiosmolar concentrations produced comparable effects on ICP reduction, brain relaxation, and systemic hemodynamics.
