    Background And PurposeWide-necked brain aneurysms therapy remains a challenge for neurointerventionalists, mainly for the high recurrence rate. Low-profile stents make feasible the treatment of these aneurysms. In our multicenter series we analyzed clinical and angiographic results of Neuroform Atlas stent-assisted coiling.Materials And MethodsFrom January 2016 to March 2017, 113 wide-necked aneurysms were discovered with CTA, MRA and DSA. The Atlas stent-assisted coiling procedures were performed under general anesthesia with sequential or jailing techniques. Six months follow-up DSA was performed to assess the recurrence rate through the modified Raymond-Roy occlusion scale (RROC). Moreover, patients were evaluated clinically to analyse the degree of disability according to the mRS. MRI was performed at 12 months evaluating both the cerebral tissue and the vessels.ResultsIn all the procedures it was feasible to navigate the Neuroform Atlas to the goal vessel and deploy the stent across the aneurysmal neck. Intra-procedural complications account for the 6.2% (7/113). The immediate occlusion rate was RROC 1 in 88%, 2 in 9% and 3 in 3% of cases. The 6 months clinical data showed mRS Score 0-1 in 96.5% of patients; 3 patients died of complications related to SAH. The 12 months follow-up showed RROC of 1 in 82%, 2 in 13% and 3 in 5% of cases. No aneurysm has been retreated.ConclusionsIn our multicenter experience the Neuroform Atlas stent assisted-coiling has shown to be a safe and effective technique for the treatment of wide-necked intracranial aneurysms with encouraging clinical and angiographic results.Copyright © 2019 Elsevier Masson SAS.
