Key Points

This meta-analysis seeks to define the incidence of cerebral hyperperfusion syndrome following moyamoya revascularization surgery.
Performed a meta-analysis of studies on moyamoya revascularization surgery.
Analyzed trends across various patient populations and surgical techniques.
Conducted meta-regression to identify variations in incidence.
Identified varying incidence rates of cerebral hyperperfusion syndrome post-revascularization across studies.
Meta-regression revealed significant trends associated with specific surgical procedures.
Cumulative evidence suggests heightened awareness of CHS risk in moyamoya intervention.

Implication

Meta-analysis examines incidence of cerebral hyperperfusion syndrome in patients undergoing moyamoya revascularization, indicating trends across populations.

Abstract

This meta-analysis aimed to determine the precise incidence of cerebral hyperperfusion syndrome (CHS) following revascularization surgery for moyamoya disease (MMD) across different patient populations and surgical procedures.
