A dual-center validation of the PIRAMD scoring system for assessing the severity of ischemic Moyamoya disease

Prior Infarcts, Reactivity, and Angiography in Moyamoya Disease (PIRAMD) is a recently proposed imaging-based scoring system that incorporates the severity of disease and its impact on parenchymal hemodynamics in order to better support clinical management and evaluate response to intervention. In particular, PIRAMD may have merit in identifying symptomatic patients that may benefit most from revascularization. Our aim was to validate the PIRAMD scoring system

Year in Review: Synopsis of Selected Articles in Neuroanesthesia and Neurocritical Care from 2022

This review is a synopsis of selected articles from neuroscience, neuroanesthesia, and neurocritical care from the year 2022 (January–November 2022). The journals reviewed include anesthesia journals, critical care medicine journals, neurosurgical journals as well as high-impact medical journals such as the Lancet, Journal of American Medical Association (JAMA), New England Journal of Medicine (NEJM), and Stroke. The summary of important articles will serve to update the knowledge of neuroanesthesiologists and other perioperative physicians who provide care to neurosurgical and neurocritical cases

Acute atrial fibrillation in emergency surgery: Is it rare?

Atrial fibrillation (AF) is a common arrhythmia with an estimated clinical prevalence of approximately 1% in the general population and as high as 9% in individuals by the age of 80 years. The aetiology is multifactorial. Systemic disease, e.g., inflammatory processes, sarcoidosis, autoimmune disorders, has also been linked to the development of AF. Myocardial dysfunction observed in sepsis could contribute to arrhythmias and inflammation per se could induce or provoke AF. We describe the successful management of an acute AF in an elderly patient scheduled for emergency laparotomy and closure of hollow viscous perforation

Intraoperative Stimulation Mapping in Neurosurgery for Anesthesiologists—Part 1: The Technical Nuances

Brain mapping has evolved tremendously in the past decade, fueled by advances in functional neuroimaging technology in neuro-oncology and epilepsy surgery. Despite this, wide anatomic-functional interindividual variability and intraoperative brain shift continue to challenge neurosurgeons performing surgery within or near eloquent brain regions. As such, intraoperative direct cortical and subcortical stimulation mapping remains the gold standard for localizing eloquent brain regions with precision for a safe and tailored resection. Intraoperative stimulation mapping (ISM) allows for maximizing the extent of resection while minimizing postoperative neurological deficits, resulting in better patient outcomes. Understanding the technical nuances of ISM is imperative for the anesthesiologist to provide better anesthetic management tailored to the surgery and stimulation mapping planned. A comprehensive search was performed on electronic databases to identify articles describing intraoperative cortical and subcortical mapping, language, and motor mapping. In the first part of this narrative review, we summarize the salient technical aspects of ISM and the common neurophysiological tasks assessed intraoperatively relevant to the anesthesiologist
