- Abstract
In the diagnostic work-up of patients suspected of a dural arteriovenous fistula (dAVF), imaging has a key role in order to diagnose the dAVF, assess its bleeding risk and choose optimal treatment strategy. Digital subtraction angiography (DSA) is the gold standard for the most detailed image of a dAVF. Nowadays four-dimensional CT angiography (4D-CTA) could possibly be an additional first-line tool in the work-up of a patient suspected of a dAVF. We describe three cases clinically suspected of a dAVF which had a diagnostic work-up with 4D-CTA as well as DSA. We evaluated the angioarchitecture of the dAVF both on 4D-CTA and DSA, with emphasis on the patterns of venous drainage as this is important in assessing the bleeding risk of a dAVF.
