Management of Arteriovenous Malformations in Pediatric Population: about two Cases

The annual incidence of brain arteriovenous malformations (AVMs) in the general population is estimated between 0.1 and 4% with an annual hemorrhage rate between 2 and 10% and a 50% risk of neurological morbidity [1]. The re-rupture rate is estimated to be 2–4% resulting in a mortality rate up to 25% [1]. This risk is higher within the first 5 years after diagnosis. In comparison with the adult population, the literature regarding pediatric presentation is scarce. However, AVMs reportedly carry a higher rate of rupture in children than in the adult population. Several morphologic AVM characteristics are associated with hemorrhagic AVM presentation, including small AVM size, deep venous drainage, and the presence of associated arterial aneurysms. We report 2 cases of hemorrhagic presentation of brain AVMs in the pediatric population and their management.
