    Application of optical frequency domain imaging to recanalized unruptured internal carotid artery aneurysm treated by flow-diverting stent-assisted coiling

    Here we report the application of optical frequency domain imaging (OFDI), a new optical coherence tomography (OCT) device, for intravascular visualization in the treatment of a recanalized unruptured internal carotid artery aneurysm that was treated initially by stent-assisted coil embolization. OFDI revealed malapposition of the stent and lack of neointimal growth at the aneurysm neck, which was treated by deployment of a Pipeline Embolization Device to overlap the stent. An angiogram performed one year after the procedure revealed perfect healing of the aneurysm and OFDI clearly demonstrated good stent apposition and total endothelialization over the aneurysm neck.
