Abstract: Introduction: Remote ischemic conditioning (RIC) is a noninvasive, transient procedure that induces brief ischemia and reperfusion. Currently, an assessment of its efficacy in treating moyamoya disease (MMD) remains lacking. This meta‐analysis synthesized data from existing randomized controlled trials (RCTs) to estimate the efficacy of RIC in MMD patients. Methods: Embase, PubMed, Wanfang, Cochrane Library, Web of Science, Scopus, and CNKI were comprehensively searched from database inception to May 8, 2026. The Cochrane risk of bias tool was used to assess the quality of the included RCTs. Statistical analyses were carried out using Review Manager Version 5.4.1. Results: RIC was associated with a lower incidence of ischemic stroke in patients with MMD (n = 228, OR: 0.22, 95% CI: 0.07–0.67, p = 0.008). No significant reduction was observed in the incidence of transient ischemic attacks (TIA) (n = 184, OR: 0.73, 95% CI: 0.36–1.47, p = 0.38), CHS (n = 152, OR: 0.28, 95% CI: 0.07–1.12, p = 0.07), or seizures (n = 152, OR: 0.26, 95% CI: 0.04–1.62, p = 0.15). Conclusion: RIC may have potential neuroprotective effects in patients with MMD, particularly regarding ischemic stroke. However, the current evidence remains limited by small sample sizes, sparse events, and substantial heterogeneity. Further adequately powered multicenter RCTs are required to confirm these findings.
