title: Emergent management of ruptured pericallosal-callosomarginal artery aneurysm using stent-assisted coil embolization.
abstract: We present a case of a ruptured bilobed pericallosal aneurysm successfully treated with coil embolization through a Neuroform stent. A 48-year-old male presented with subarachnoid hemorrhage (SAH) following rupture of a previously clipped aneurysm at the bifurcation of the pericallosal and callosomarginal arteries, primarily along the pericallosal artery, Hunt and Hess grade 5. After an initial unsuccessful attempt to embolize the wide-neck aneurysm with a detachable coil, a 4x15 Neuroform stent was uneventfully deployed across the aneurysm neck followed by successful coil embolization using detachable coils. We believe this case describes the first successful use of the Neuroform stent to assist in coiling of a wide-neck pericallosal-callosomarginal aneurysm. This case highlights the expanding role of emergency endovascular therapies to manage severe SAH.
