Abstract

Objective: Characterize clinical features and evaluate the clinical outcome of endovascular embolization treatment intracranial arteriovenous malformations in patients aged ≤ 18 years. Subjects and methods: A cohort of children (age ≤ 18 years) with arteriovenous malformations (AVMs) from 2020 to 6/2024 was included. Predictors studied included patient gender, age, and angioarchitectural features, including AVM location, nidus morphology and size, venous drainage, and associated aneurysms. Treatment method, complications and outcomes were recorded. Results: 23 patients aged ≤ 18 wwere included, mean of age 15.4 ± 2.5, male 52.2%. The most common location of AVM is temporal (21.7%), temporal parietal 14.7% and basal ganglia 14.7%. Nidus size 0-3 accounted for 62.5%. 31.9% of patients had the deformity completely obliterated. There was 1 patient with bleeding due to rupture of the pseudoaneurysm, 1 patient with cerebral infarction after intervention. At 90 days, the rate of patients achieved good functional outcome (mRS ≤ 2) was 60.9%. Conclusion: Endovascular intervention is feasible and safe for pediatric patients. The rate of complete occlusion can be achieved with small AVMs; for large AVMs, pseudoaneurysm can be obliterated or adequately reduced in size.
