Dural arteriovenousfistula presenting as reversible dementia
Article | IMSEAR | ID: sea-225698
ABSTRACT
DAVF is an abnormal connection between arteries and veins, where supply is mainly through branches arising from the external carotid artery. A 30 years old male had multiple episodes of seizures and progressive behavioral and cognitive decline, inattentionand disorientation to time, place and person, along with ptosis and ophthalmoplegia in the right eye. DSA provided a definitive diagnosis of hypervascular Dural AV fistula at the right transverse sigmoid junction with significant cortical venous hypertension. Through femoral access, both underwent transarterial embolization through the Middle Meningeal branch of the right external carotid artery using onyx, resulting in complete occlusion of fistula and resolution of venous hypertension. Post embolisation,cognitive function assessment revealed increased attention span and improved orientation with time,place and person. Thus, DAVF can be one of the rare but reversible causes of dementia. Early diagnosis and treatment may help to dramatically improve patients� clinical condition and minimize long-term disability
