Efficacy and safety of flow diverters in small intracranial aneurysms: a systematic review and single-arm meta-analysis.

ABSTRACT:

Objective

This study aimed to evaluate the efficacy and safety of flow diverters (FDs) in the treatment of small intracranial aneurysms (≤10 mm).

Methods

PubMed, Embase, Web of Science, and Cochrane Library were comprehensively searched up to July 2025. Eligible studies included retrospective cohort studies reporting angiographic and clinical outcomes of FD treatment in small intracranial aneurysms. Data analysis was conducted using STATA 15.0. Pooled proportions and 95% confidence intervals (CIs) were calculated using Freeman-Tukey double arcsine transformation. Publication bias was evaluated using funnel plots and Egger's test.

Results

Ten retrospective studies comprising 2,275 patients with 1,938 aneurysms were included. The pooled complete or near-complete occlusi
