Background and purpose To evaluate the feasibility, safety, efficacy of endovascular treatment with flow diverters (FD) in patients recanalised multitreated aneurysms, a retrospective, multicenter, single-arm study. Materials methods The study included 29 aneurysms who were treated by FDs (Silk or Pipeline device). Per post procedural complications morbidity mortality rates evaluated. Additionally, functional outcomes (mRS) at 1 month (short-term) 3–4 months (mid-term) compared pre-operative mRS (before procedure). Mid-term angiographic follow-up was performed assessing aneurismal occlusion 3-grades scale (complete occlusion, neck remnant, aneurysm remnant). Results FD placement achieved all patients. Two misdeployments necessitated balloon dilatation two associated stent delivery one patient. Permanent related to 6.9% (2/29), transient 10.3% (3/29) due 0.0% (0/29). One patient died from myocardial infarct four weeks after procedure. 25/29 (86.2%) had final good outcome, 26/29 (89.7%) unchanged whereas 2/29 (6.9%) clinical worsening. Angiographic showed complete 17/28 (60.7%), remnants 6/28 (21.4%) residual 5/28 subjects (17.9%). Conclusion Flow diverter is feasible safe aneurysms. procedure high percentage as well anatomical results mid-term (82.1%). Disclosures L. Pierot: 2; C; Covidien, Microvention, Stryker. A.
