Posterior−anterior view of the right internal carotid artery showing an incidental wide-necked anterior communicating artery aneurysm (A). Three-dimensional reconstruction showing the aneurysm with a neck width of 5 mm (B). Dyna-CT reconstruction showing the position of a 4-15-6 mm pCONUS2 HPC within the aneurysm and along the right A1 segment (C). Procedure was performed under acetylsalicylic acid (ASA) as single antiplatelet therapy. Working projection for coil occlusion of the aneurysm 39 days after pCONUS HPC implantation (D). Final run after coiling of the aneurysm with small neck remnant visible (E). No high signal intensity spots were observed in the diffusion-weighted imaging performed the following day. Follow-up angiogram 8 months after coil occlusion (F, G) showed complete occlusion of the aneurysm and severe intimal hyperplasia along the stent-shaft (compare D and H). VerifyNow confirmed insufficient inhibition for ASA (ARU:569).
