ObjectiveCerebral arteriovenous malformations (AVMs) are a challenging pathology in pediatric patients, carrying a high risk of morbidity and mortality. Treatment modalities include resection, endovascular embolization, and stereotactic radiosurgery. There is currently no consensus favoring one modality over another. Timing of multimodal therapy with embolization/stereotactic radiosurgery and resection is not well explored in the literature. We present a series of pediatric patients with AVMs, with special attention directed to the timing of treatment.MethodsElectronic medical records of all pediatric patients (<18 years old at treatment) with AVMs treated at our institution were retrospectively reviewed after institutional review board approval. Demographic information, AVM characteristics, treatment variables, and outcomes were recorded.ResultsIn our cohort of 27 patients, 21 (77.8%) presented with a ruptured AVM. Of these patients, 6 (28.6%) had a Glasgow Coma Scale score of 3-10 and underwent treatment within 24 hours of presentation, and 10 (47.6%) with a Glasgow Coma Scale score of 12-15 were treated between 24 and 120 hours after presentation. The remaining 5 patients (23.8%) were treated 3 weeks to 14 months after AVM rupture. Regardless of rupture status, 96% of our cohort had a modified Rankin Scale score of 1-2 at most recent follow-up.ConclusionsWe present our institution's experience with pediatric AVMs, focusing on the timing of treatment. Based on our experience, early treatment of AVMs seems to be safe and effective regardless of rupture status.Copyright © 2024 Elsevier Inc. All rights reserved.
