The Application of Neuroform Atlas Stent-Assisted Coiling in Ruptured Intracranial Aneurysms: A Multicenter Retrospective Study.

Abstract

The Neuroform Atlas stent is increasingly used in the management of ruptured intracranial aneurysms (RIAs). However, its safety and efficacy in RIAs remain to be fully established. This study aimed to assess the safety and efficacy of Neuroform Atlas stent-assisted coiling (SAC) for the treatment of RIAs. We conducted a multicenter retrospective cohort study of patients with RIAs treated with Neuroform Atlas SAC between January 2020 and May 2023. Clinical characteristics, angiographic outcomes, and follow-up data were analyzed. A total of 101 patients with 101 RIAs were included. All aneurysms were treated using Neuroform Atlas SAC. The mean aneurysm size was 4.9 mm, and the average neck width was 3.3 mm. Immediate Raymond-Roy occlusion class I was achieved in 59.4% of patients and increased to 87.7% at the latest follow-up. The mean follow-up duration was 257.9 days. Favorable clinical outcomes were observed in 92.1% of surviving patients with available follow-up. Our study demonstrated the safety and efficacy of Neuroform Atlas SAC in the treatment of RIAs.
