Clinical and Anatomic Insights From a Series of Ethmoidal Dural Arteriovenous Fistulas at Barrow Neurological Institute

Transnasal flow reduction in endovascular treatment for anterior cranial fossa dural arteriovenous fistula

“…TAE for ACF–dAVF is a useful option following recent developments in endovascular devices; for example, flexible and trackable microcatheters, microguidewires, embolic agents and imaging devices [ 1–5 ]. TAE can be performed safely and successfully only in patients with less tortuous dilated OphAs; therefore, only 19–46% of patients with ACF–dAVF undergo TAE, and the success rate is 0–63% [ 1 , 3 , 5 ].…”

“…For anterior cranial fossa–dural arteriovenous fistula (ACF–dAVF), transarterial embolization (TAE) is a useful option as endovascular devices have progressed [ 1–5 ]. Liquid embolic agents are usually injected from a microcatheter positioned just proximal to the shunt pouch.…”

“…Liquid embolic agents are usually injected from a microcatheter positioned just proximal to the shunt pouch. However, TAE can be performed only in selected patients with suitable angiographic anatomy, to reduce complications such as vision loss [ 1 ].…”

Cerebral Dural Arteriovenous Fistulas—an Update on Pathophysiology, Natural History and Treatment

“…[33][34][35][36][37][38] This often includes ethmoidal fistulas that cannot be safely accessed via the ophthalmic artery without considerable risk to vision as well as tentorial/petrosal fistulas lacking an adequate caliber transarterial conduit. 38,39 Fortunately, these two fistula types are relatively facile surgical targets. In one study of 20 patients with high risk dAVFs undergoing surgical disconnection, angiographic cure was achieved in all cases with a morbidity/mortality rate of 10%.…”

“…35 In particular, surgical results for ethmoidal fistulas are excellent, with high obliteration rates (99-100%) and low morbidity (1-2%). [39][40][41] 22 Borden-Schucart 1995 23 Cognard-…”
