The study evaluates chronic subdural hematoma (cSDH) middle meningeal artery (MMA) embolization efficacy and safety. A prospective interventional study was conducted in Viet Duc Hospital from November 2021 to April 2024. All consecutive cSDH MMA embolization patients were included. Clinical and imaging data were collected before and one month after treatment. The study included 31 42-cSDH patients. Of these, 25.8% had hematoma evacuation, 83.9% were treated with surgery and embolization, and 16.1% with embolization alone. 92.9% of procedures used polyvinyl alcohol particles. The success rate was 92.9% and complications 7.1%. Asymptomatic external carotid artery vasospasm and MMA rupture occurred. Functional improvement occurred in 91.7% of patients one month after treatment. Significantly lower mean modified Rankin Scale (mRS) score (0.2±0.7 vs. 1.7±0.9; P=0.000) and higher proportion of patients with ≤2 mRS score (95.8% vs. 74.1%) were observed after treatment. Hematoma thickness decreased significantly (P=0.00) from 21.5±7.9 mm to 8.3±4.1 mm. The midline shift decreased significantly from 7.4±5.0 mm to 0.7±1.2 mm (P=0.00). Just one patient (4.2%) needed surgery. MMA embolization alone or with surgery appears to treat cSDH safely and effectively.
