Low-Profile Neuroform Atlas Stent-Assisted Coiling of Intracranial Aneurysms: Single-Center Initial Experience

Abstract

Background Neuroform Atlas stent is a relatively new device used for stent-assisted coiling (SAC) of wide-necked intracranial aneurysms. Purpose To elaborate the initial experience in a single center to assess the efficacy and initial results of Neuroform Atlas for SAC of intracranial aneurysms. Methods Between February 2017 and September 2018, eight patients (five females, three males; mean age 56 years) underwent SAC with Neuroform Atlas. Results Five unruptured and three ruptured wide-necked aneurysms were treated with Neuroform Atlas SAC. Immediate complete occlusion modified Roy-Raymond class 1 (MRRC 1) or mild neck residue class 2 (MRRC 2) was achieved in three patients and five other patients had minimal residual interstitial filling of the aneurysm (MRRC 3b). One patient with ruptured intracranial aneurysm succumbed to the illness in the first postoperative day due to massive rebleed. Other seven patients remained clinically asymptomatic in the follow-up period. Patent stent was noted at three to seven months follow-up magnetic resonance angiography (MRA) in five patients. Complete occlusion of the aneurysm was noted in three patients, and minimal residual aneurysm was seen in two patients. Conclusion Neuroform Atlas stent is safe and effective in achieving good angiographic outcome in complex intracranial aneurysms.
