A Ruptured Intraorbital Ophthalmic Artery Aneurysm, Associated with a Dural Arteriovenous Fistula: Combined Transarterial and Transvenous Endovascular Treatment.

Background: True aneurysms of the ophthalmic artery (OA) are extremely rare and most often arise at the origin of this artery. We present the endovascular management of a ruptured intraorbital OA aneurysm and of an associated dural arteriovenous fistula (dAVF). Patient: A patient with a ruptured intraorbital ophthalmic artery aneurysm, associated with a dAVF with cortical drainage presented with acute visual loss and intra- and periorbital hematoma. The aneurysm was treated by endovascular coil occlusion. The dAVF was occluded by transvenous obliteration of the draining basal vein of Rosenthal. Both intraorbital ophthalmic artery aneurysms and their rupture are extremely rare. Conclusion: Transvenous treatment of dAVFs is well feasible even with very far going catheterization, in this case to the origin of the basal vein of Rosenthal. [ABSTRACT FROM AUTHOR]
