Objective To investigate the safety and efficacy of the Neuroform Atlas stent in the treat-ment of small and micro internal carotid artery aneurysms.Methods The clinical data of 58 patients with small or micro internal carotid artery aneurysms embolized with Neuroform Atlas stent-assisted coils from August 2020 to August 2023 were analyzed retrospectively.There were 42 cases(72.4％)of small aneurysms and 16 cases(27.6％)of microaneurysms.Results Intraoperative stent implantation failed in 2 patients(3.4％),and the rest 56 patients were embolized with the assistance of Neuroform Atlas stents.Intraoperative aneurysm rupture occurred in 2 cases(3.4％)and postoperative ischemic event occurred in 2 cases(3.4％).Immediately after operation,Raymond grade Ⅰ was observed in 33 cases(78.6％),grade Ⅱ in 6 cases(14.3％)and grade Ⅲ in 3 cases(7.1％)of small aneurysms,respectively.In microaneurysm cases,Raymond grade Ⅰ was in 7 cases(43.8％),grade Ⅱ in 8 cases(50.0％)and grade Ⅲ in 1 case(6.2％),respectively.The emboli-zation degree of small aneurysms immediately after operation was better than that of microaneurysms(P＜0.05).During the follow-up of 3～6 months after operation,there were 38 cases of Raymond grade Ⅰ(90.5％),3 cases of grade Ⅱ(7.1％),1 case of grade m(2.4％)in patients with small aneurysms,and 13 cases of Raymond grade Ⅰ(81.2％),2 cases of grade Ⅱ(12.5％),1 case of grade Ⅲ(6.3％)in patients with microaneurysms.There was no significant difference between the two groups(P＞0.05).One month af-ter operation,there were 51 cases whose modified Rankin scale(mRS)score was between 0 and 2,and at six months after operation,mRS score of all the patients was between 0 and 2.There was no significant difference in postoperative mRS scores between patients with small aneurysms and patients with microaneurysms.Conclu-sion The success rate of Neuroform Atlas stent-assisted coil implantation in the treatment of small and micro internal carotid artery aneurysms is high,and the incidence of intraoperative and postoperative complications is low,and the long-term prognosis of the patients is good.
