  "abstract": "Introduction Endovascular treatment of intracranial aneurysms has evolved significantly, with intrasaccular devices (e.g., Contour) offering an alternative to coiling or stent-assisted techniques. However, real-world efficacy and safety data remain limited.Aim of study To evaluate technical success, safety, and short-term occlusion rates of intrasaccular flow disruption using the Contour device at a single neurointerventional centre.Method A retrospective review of consecutive patients treated from 2023 to 2025 was performed. Demographics, aneurysm features, procedure details, complications, and follow-up at 6 and 24 months were analyzed. Technical success was defined as device deployment without bailout stenting. Occlusion was rated by the Raymond-Ray (RR) classification.Results Seventeen patients (18 unruptured aneurysms) were treated (mean age 61.8 years). Aneurysm location included middle cerebral artery (44.4%), anterior communicating artery (33.4%), and basilar artery (22.2%). Median aneurysm diameter was 6.0 mm, with dome-to-neck ratio below 2 in all cases (mean 1.52 (95% CI 1.38–1.65)). Technical success was achieved in 94% (17/18), with one device failure to open. No procedural complications occurred. At 6 months, 9 patients presented for follow-up: RR I or II was achieved in 88.8% (8/9). One residual aneurysm (RR III) demonstrated only neck remnant (RR II) at 24 months.Conclusion Our single-centre experience demonstrates that Contour intrasaccular flow disruption achieves a high technical success rate and favorable occlusion outcomes with minimal complications. Short-term follow-up indicates durable aneurysm closure, though further research is needed to assess long-term outcomes.Conflict of Interest No",
