Intraosseous Cranial Dural Arteriovenous Fistula Treated with Transvenous Embolization

Abstract

BACKGROUND AND PURPOSE:We analyzed the angiographic architecture of intraosseous dural arteriovenous fistulas (DAVFs) and evaluated the use of transvenous embolization for curative treatment.

Intraosseous Arteriovenous Malformation of the Sphenoid Bone Presenting with Orbital Symptoms Mimicking Cavernous Sinus Dural Arteriovenous Fistula: A Case Report

“…Angiographic diagnosis of intraosseous AVM in the skull base was difficult because the nidus was located on the left side sphenoid body and adjacent greater wing, not far from the usual osseous type of skull base DAVF 4)7). In contrast to a typical osseous DAVF, our patient's condition was characterized by a polygonal shaped venous chamber - not a network of fine vessels - within the bone as a large ectatic draining vein.…”

Endovascular Treatment of Intracranial Dural Arteriovenous Fistulas

“…These vessels can have submillimeter calibers and be extremely tortuous, making penetration with even dilute liquid embolics problematic. 17 This follows from observations that closure of a fistula is more likely if the microcatheter can be positioned immediately adjacent to the fistula, which by definition is on the inner side of the calvarium.…”

Intracranial Dural Arteriovenous Fistulae

“…Rates of complete fistula obliteration by this technique are high, with reported ranges of 71% to 87%. [68][69][70][71] Specific risks include venous infarction and dural sinus perforation. 1,66 DAVF involving the cavernous sinus are particularly amenable to transvenous embolization, with high rates of successful lesion closure.…”
