Abstract

Ethmoidal dural arteriovenous fistulas (dAVFs) are rare, accounting for 1–1.5% of all intracranial malformations.1 However, they may have angiographic features that increase the risk of rupture: cortical venous drainage, venous ectasia, venous stenosis and high arterial flow. If the dAVF has these angiographic features, treatment may be indicated regardless of the clinical presentation.2–4 In this neurosurgical …
