Introduction Ruptured cerebral aneurysms require immediate intervention to prevent rebleeding and reduce the risk of intracranial pressure-related complications. Endovascular approaches are the preferred option in most emergency cases. The Contour intracranial remodeling device has been proposed for use in wide-neck aneurysms due to its rapid deployment, simplified sizing, and ease of handling.Aim of study To evaluate the safety, feasibility, and early efficacy of the Contour device in the urgent endovascular treatment of ruptured intracranial aneurysms.Method A retrospective study was conducted across two tertiary neurovascular centers, including 15 patients who underwent emergency treatment with the Contour device. Primary outcomes were the absence of rebleeding and acute procedural complications. Secondary outcomes included follow-up angiographic assessment of aneurysm recurrence, device stability, and long-term occlusion. Procedural parameters such as sizing, deployment time, and operator experience were also analyzed.Abstract A351 Figure 1Results All patients achieved immediate occlusion of the aneurysm sac with no post-procedural rebleeding or acute device-related complications. Follow-up imaging showed a small number of neck recurrences. One patient experienced device migration with partial aneurysm reperfusion, requiring retreatment. Overall, the device allowed short procedure times and was effective even in hemodynamically unstable patients. Its simplified sizing system reduced the need for device exchange. The procedure was safely performed by operators with varying experience levels.Abstract A351 Figure 2Conclusion The Contour device appears to be a safe and efficient option for the urgent management of ruptured aneurysms, particularly in wide-neck morphologies. These preliminary results support its use in emergency settings, though further prospective studies are needed to assess long-term outcomes and refine patient selection.Conflict of Interest No
