Abstract
BackgroundRevascularization surgery decreases the long-term risk of stroke in children with moyamoya but carries an increased risk of perioperative ischemic events. Evidence-based approaches to safe perioperative management of children with moyamoya are limited. We aimed to understand practice variability in perioperative moyamoya care. MethodsNeurologists, neurosurgeons, and intensivists practicing in North America with expertise in perioperative pediatric moyamoya care participated in a 138-item anonymous survey focused on interdisciplinary perioperative care surrounding indirect revascularization surgery. ResultsMany perioperative care practices vary substantially between participants. Timing of resumption of antiplatelet therapy postoperatively, choice of sedative agents and vasopressors, goal blood pressures, rate and duration of intravenous fluid administration, and red blood cell transfusion thresholds are among the most variable practices. ConclusionsThis practice variability survey highlights several important knowledge gaps and areas of equipoise that should be targets for future investigation and consensus-building efforts.
