Endovascular treatment as first-line therapy in Spetzler-Martin grade III brain arteriovenous malformations: a systematic review and meta-analysis

Key Points

• The aim is to evaluate the effectiveness of endovascular treatment as the primary therapy for Spetzler-Martin grade III arteriovenous malformations.
• Conducted a systematic review and meta-analysis of available literature
• Analyzed rates of functional independence and obliteration
• Assessed morbidity and mortality associated with treatment
• Endovascular treatment is linked to high rates of functional independence
• Obliteration rates are moderate
• Permanent morbidity rates are low
• Mortality is negligible
• Nearly half of patients may need additional treatments
