Our study suggests that seizures mainly occur in AVMs with superficial drainage. Other predisposing factors include male sex, increasing AVM size, and frontal lobe and arterial borderzone location. Whether or not interventional treatment has an effect on the long-term risk of epilepsy remains to be determined.
Diaphragms are a rare cause of recurrent embolic strokes which are often not detected with non-invasive imaging. Stenting appears to be a therapeutic option in stroke secondary prevention. These observations suggest that conventional angiography should be performed in cases of recurrent ischaemic strokes in the territory of a single artery and in cases of ischaemic stroke of undetermined aetiology in young adults when the usual investigations are negative.
BACKGROUND AND PURPOSE:Recently some series have been published about the use of Onyx for the treatment of DAFVs with satisfactory results. Our aim was to describe the treatment of different types of intracranial DAVFs with transcatheter injection of Onyx through an arterial approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
