Abstract

A cross-sectional descriptive study of 89 patients diagnosed with cerebral arteriovenous malformations (AVMs) using digital subtraction angiography (DSA) at the National Children’s Hospital from 2020 to 2024. The results showed the most common age group being 5 to 10 years old (50.6%) and a male-to-female ratio of 1.11:1. Out of 89 patients, 74 were admitted with cerebral hemorrhage, presenting with common symptoms such as headache (87.6%), vomiting (73%), focal paralysis (15.7%), and seizures (13.5%). All patients underwent DSA, which revealed that 89.9% of the malformations were located supratentorial, with the middle cerebral artery being the most common blood supply to the malformation (29.2%). The malformations were often small less than 30 mm (66.3%), and were mostly classified as Spetzler-Martin grade II and III (38.2% and 37.2%). Cerebral arteriovenous malformations in children are often diagnosed when they rupture. DSA helps to evaluate detailed characteristics such as location, size, and associated lesions of the malformation.
