Abstract Background: There have been few studies on endovascular treatment (EVT) of the brain arteriovenous malformations (BAVMs) involving the anterior cerebral artery (ACA). Methods and materials: This study continuously enrolled 60 patients with ACA-BAVMs treated with EVT. ACA-BAVMs were divided into three types: type I BAVMs were those located below and in front of the corpus callosum genu, type II BAVMs were those located in the upper area of the corpus callosum from the genu to the anterior trunk, and type III BAVMs were those located in the upper area from the anterior trunk to the splenium of the corpus callosum. Results: The patients were aged 10 to 72 years (mean, 35.4 ±17.0 years) and included 28 females (46.7%, 28/60). BAVMs were type I (15%, 9/60), type II (25%, 15/60), and type III (60%, 36/60). Statistical analysis showed that posterior cerebral artery (PCA) tended to be involved in type II and III BAVMs. For EVT, immediate complete or nearly complete embolization was achieved in 34 (56.7%, 34/60) cases. During EVT, there were 3 cases of intraoperative bleeding (5%, 3/60), which tended to occur in type I and II ACA-BAVMs. At discharge, 80% of patients had a GOS score of 5. During the follow-up, 89.3% of patients had mRS scores of 0 and 1. Conclusion: This study showed that EVT carries a risk of intraoperative bleeding for type I and II BAVMs, for type II and III BAVMs, the PCA can often be involved in EVT. In general, EVT can result in a good prognosis for ACA-BAVMs.

Bleeding from ruptured brain arteriovenous malformations (bAVMs) represents the most prevalent cause of pediatric intracranial hemorrhage, being also the most common initial bAVM manifestation. A therapeutic approach in these patients should aim at preventing rebleeding and associated significant morbidity and mortality. The purpose of this study was to determine the clinical outcomes of pediatric patients who initially presented at our institution with ruptured bAVMs and to review our experience with a multimodality approach in the management of pediatric ruptured bAVMs. We retrospectively reviewed pediatric patients’ medical records with ruptured bAVMs who underwent interventional treatment (microsurgery, embolization, or radiosurgery; solely or in combination) at our institution between 2011 and 2020. We identified 22 patients. There was no intraoperative and postoperative intervention-related mortality. Neither procedure-related complications nor rebleeding were observed after interventional treatment. Modified Rankin Scale (mRS) assessment at discharge revealed 19 patients (86.4%) with favorable outcomes (mRS 0–2) and 3 patients (13.6%) classified as disabled (mRS 3). Microsurgery ensured the complete obliteration in all patients whose postoperative digital subtraction angiography (DSA) was available. Management of high-grade bAVMs with radiosurgery or embolization can provide satisfactory outcomes without a high disability risk.
