Objective To investigate the safety and efficacy of Neuroform Atlas stent-assisted coiling in the treatment of intracranial wide-necked aneurysms.Methods This was a retrospective analysis of 29 patients harboring 29 intracranial wide-necked aneurysms treated with Neuroform Atlas stent-assisted coiling from March 2022 to February 2023.Results Of the 29 aneurysms,9 patients presented with acute ruptured aneurysms and 20 patients with unruptured aneurysms.A total of 29 Neuroform Atlas stents were successfully releases in 29 cases and there was 1 case with intraoperative complication.Immediate postoperative DSA revealed that 25 cases (86.2％) were classified as grade Ⅰ of the modified Raymond scale,1 case (3.4％) was classified as grade Ⅱ,and 3 cases (10.3％) were classified as grade Ⅲa.After the operation,1 patient died of acute pulmonary embolism.During the postoperative follow-up period of 3～6 months,the clinical follow-up was completed in 28 cases,of whom 26 cases had an mRS score of 0,1 case had a score of 1,and 1 case had a score of 3;the imaging follow-up was completed in 18 cases,of whom 15 cases (83.3％) were classified as grade Ⅰ of the modified Raymond scale,1 case (5.6％) was classified as grade Ⅱ,and 2 cases (11.1％) were classified as grade Ⅲa.No stenosis of the parent artery or delayed thrombotic events were found.Conclusion Neuroform Atlas stent-assisted coil embolization for wide-necked intracranial aneurysms has a high aneurysm occlusion rate and a low incidence of perioperative complications,with good safety and efficacy.However,its long-term efficacy still requires further follow-up and observation.
