Critical Care Nursing in Moyamoya Disease: Complexities and Considerations.

Moyamoya disease is a rare progressive cerebrovascular disorder involving stenosis of major intracranial arteries and the formation of fragile collateral vessels. Patients face lifelong risks of ischemic and hemorrhagic stroke. Surgical revascularization is the definitive treatment, aimed at restoring cerebral perfusion and reducing neurologic injury. Postoperative care is among the most complex in neuroscience nursing. Critical care nurses play a vital role in managing cerebral perfusion, conducting frequent neuro assessments, regulating blood pressure, and preventing seizures. Success requires individualized hemodynamic targets, early detection of complications like hyperperfusion or ischemia, psychosocial support, and close interdisciplinary collaboration.
