Dural arteriovenous fistula of the anterior fossa treated with the Onyx liquid embolic system and the Sonic microcatheter

Abstract

We report an association of new technologies (the Onyx liquid embolic system and the Sonic microcatheter) for transarterial embolization through the anterior branch of the middle meningeal artery of a dural arteriovenous fistula (DAVF) of the anterior fossa. The place of endovascular treatment in anterior fossa DAVFs is reviewed, and its clinical implications discussed in light of the case of a patient whose management was modified by this association of new technologies.

The Use of Onyx in Different Types of Intracranial Dural Arteriovenous Fistula

“…This can present technical challenges to selective navigation of the microcatheter, and we must respect the anatomic limitations to avoid complications. [14][15][16] Another distinguishing feature of our study was the use of Onyx 34 in a subset of DAVF treatments. This higher attenuation version of the Onyx copolymer was used in 6 patients to mitigate distal migration of the embolic agent in fistulas that contained a high-flow shunt.…”

The Usefulness of Subcutaneous Infiltration of Epinephrine-Containing Lidocaine for Curative Transarterial Embolization of Dural Arteriovenous Fistula

“…In the past decade, many reports have described the feasibility of transarterial embolization (TAE) with liquid embolic materials as a curative treatment for high-grade d-AVFs [2][3][4][5][6][7][8][9][10][11][12][13][14][15] . Those reports used NBCA or ethylene vinyl al-to reduce the blood flow from transosseous competing feeders.…”

Arteriovenous Fistula Arising From the Persistent Primitive Olfactory Artery With Dual Supply From the Bilateral Anterior Ethmoidal Arteries -Case Report-

“…Arteriovenous fistula (AVF) in the anterior cranial fossa is a rare but aggressive entity manifesting as intracerebral hemorrhage or subarachnoid hemorrhage, 1,5,11) and usually supplied by the anterior ethmoidal artery or exceptionally by the branches of the anterior cerebral artery. 2,3) Surgical obliteration of the abnormal shunt is the preferred therapeutic option, but recently endovascular management or radiosurgery and multidisciplinary approaches have also become potential therapeutic approaches.…”

“…2,3) Surgical obliteration of the abnormal shunt is the preferred therapeutic option, but recently endovascular management or radiosurgery and multidisciplinary approaches have also become potential therapeutic approaches. 1,[4][5][6]9,11) The persistent primitive olfactory artery (PPOA) is a rare remnant of the fetal arteries that usually dwindles but infrequently persists as a small branch accompanying the olfactory nerve into the nasal cavity, and a larger derivative extends laterally to enter the mesial part of the anterior perforated substance as the recurrent artery of Heubner at 44 days ovulation age. The PPOA remains only as part of the recurrent artery of Heubner in normal vascular developments.…”
