Arteriovenous Malformation

Arteriovenous malformations of the brain are abnormal bunch of blood vessels that can rupture causing bleeding, or may cause seizures. Brain imaging (CT, MRI) is required for early diagnosis, while definitive treatment is carried out after cerebral angiography. Treatment implies craniotomy and excision of the AVM, which can be done safely in majority of the cases. Embolisation and radiosurgery are acceptable substitutes, but carry risk of further bleeding.
