ROLE OF ENDOVASCULAR EMBOLIZATION IN THE MULTIDISCIPLINARY MANAGEMENT OF RUPTURED BRAIN ARTERIOVENOUS MALFORMATIONS

Brain arteriovenous malformations (bAVMs) are congenital defects of vasculogenesis, the natural history of which is characterized by a significant morbidity and mortality related to the risk of bleeding. Their management remains challenging, since complete eradication is often difficult. Embolization, surgery, or radiosurgery alone are safe and effective for small unruptured AVMs, while a multidisciplinary approach should be pursued for larger ones. We report a case of intracerebral haemorrhage due to the rupture of a large bAVM, for which a multidisciplinary approach was adopted: endovascular partial embolization followed by complete surgical removal.
