Traumatic ophthalmic artery pseudoaneurysm coiled with a steerable microcatheter.

Traumatic pseudoaneurysms of the ophthalmic artery (OphA) are a rare phenomenon.1,2 They can result in subarachnoid hemorrhage if they occur within the dura. Left untreated these lesions are dangerous and have a very high risk of rehemorrhage. In these cases, the acute angulation of the OphA off the internal carotid artery, the proximal location of these intradural lesions and the inability to achieve distal microwire purchase make the catheterization and coil embolization of these lesions challenging. We utilized a deflectable tip microcatheter for the treatment of this lesion. This publication describes the use of a deflectable tipped microcatheter in a case of a traumatic intradural pseudoaneurysm of the OphA treated by endovascular therapy. We review the techniques which were applied to take best advantage of the unique properties of this novel microcatheter and facilitate the catheterization and dense coil packing of this difficult aneurysm.
