Key Points

This study aims to assess the efficacy and safety of flow diverters for treating middle cerebral artery aneurysms.
Retrospective analysis of 139 patients treated with flow diverters for MCA aneurysms from 2017 to 2024.
Clinical and imaging data (DSA, MRA, CTA, MRI) collected at various follow-up intervals.
Outcomes evaluated using modified Rankin Scale (mRS) and predictors of occlusion analyzed.
Complete occlusion achieved in 55.1% of aneurysms, and adequate occlusion in 76.4%.
High occlusion rates with p48 MW-HPC (91.7%) and PED Vantage (89.5%) devices.
Complications occurred in 9.5% of patients; permanent deficits were 2.6%, and mortality rate was 0.9%.
