Abstract

Objective Clinical data on the new Neuroform Atlas stent for treatment of intracranial aneurysms is limited. We report our experience in stent-assisted coiling procedures of complex, predominantly wide-necked aneurysms. Methods This is a retrospective study of consecutive patients treated with the Neuroform Atlas stent between August 2014 and November 2018 at three German tertiary care centers. We evaluated the complication rate, clinical outcome and angiographic result at mid-term follow-up. Results Thirty-seven aneurysms (elective: 23, previous subarachnoid hemorrhage: 14) were treated in 37 patients (mean age: 59.4 years, 62.2% females). Stent-assisted coiling was successful in all cases, achieving immediate complete aneurysm occlusion by coiling in 83.8% and neck remnants in 16.2%. At 6-month angiographic follow-up, complete aneurysm occlusion was obtained in 80.8% (21/26), neck remnants in 11.5% (3/26) and aneurysm remnants in 7.7% (2/26). Retreatment was necessary in 7.7%. Ischemic stroke occurred in one patient (2.7%). At 6-month clinical follow-up, procedure-related permanent morbidity was 2.7%. Conclusions Our results demonstrate that treatment of intracranial aneurysms with the Neuroform Atlas stent is associated with low morbidity and a high aneurysm occlusion rate at mid-term follow-up. Further studies will be necessary to confirm our results.
