Abstract

Objective: To evaluate the outcomes and safety of endovascular intervention in the treatment of pial arteriovenous fistulas (pAVF) in pediatric patients at Vietnam National Children's Hospital. Materials and Methods: A retrospective descriptive study was conducted on pediatric patients diagnosed with pial arteriovenous fistulas (pAVF) and treated with endovascular intervention at National Children's Hospital from July 2019 to February 2025. Clinical data, imaging findings, interventional techniques, complications, and treatment outcomes were collected and analyzed. Results: A total of 13 pediatric patients (5 males, 8 females) were treated, with a mean age of 541 ± 810 days. The most common clinical symptoms included seizures (46.2%), heart failure/pulmonary hypertension (30.8%), intellectual developmental delay (23.1%), and intracranial hemorrhage (30.8%). The majority of lesions were supratentorial (84.6%) and had multiple fistulous connections (84.6%). Endovascular techniques primarily utilized n-butyl cyanoacrylate (n-BCA), coils, or a combination of embolic materials to occlude the fistulas. In all cases, the occlusion rate was >50%, with 38.5% of cases achieving complete obliteration. Complications were observed in 30.8% of cases. Conclusion: Pial arteriovenous fistulas (pAVF) are rare vascular malformations but can lead to high morbidity and mortality rates. Endovascular intervention is an effective treatment method with a low complication rate.
