Protocol for a future systematic review on pediatric limb arteriovenous malformationsPlanned review will study treatments for limb blood vessel tangles in kids

BackgroundPeripheral arteriovenous malformations (pAVMs) of the limbs are common in children, with distinct clinical features and high intervention difficulty. Existing research on its interventions is controversial due to non-standardized criteria, small-sample uncontrolled studies and inconsistent efficacy evaluation, leaving clinicians without high-quality evidence-based guidance.Methods and analysisThis study will conduct a PROSPERO-registered systematic review, searching PubMed, Embase and other databases for relevant clinical studies. Two researchers will independently screen literature, extract data and assess evidence quality via GRADE. RevMan 5.4 will be used for qualitative and quantitative statistical analysis, with subgroup and sensitivity analyses to explore heterogeneity. Primary outcome is short-term symptom improvement rate within 3 months post-intervention; secondary outcomes include adverse event incidence and quality of life.Ethics and disseminationEthical approval is not required because this study is a secondary analysis of existing data. We will disseminate the findings through peer-reviewed publications.Clinical Trial RegistrationPROSPERO (CRD420261326988).
