Use of the Neuroform Atlas Stent or LVIS Jr Stent for Treatment of Unruptured Intracranial Aneurysms in Parent Arteries of <2 mm in Diameter: A Multicenter Experience
Retrospective study demonstrates higher incomplete apposition with LVIS Jr than Neuroform Atlas stents in small parent vessels, highlighting anatomic risks during microstent selection.
Key Points
Stent assisted coiling secures unruptured intracranial aneurysms in vessels under 2 mm, but the lvis jr stent shows higher rates of incomplete stent apposition at the neck.
Conebeam ct revealed incomplete stent apposition in 11 lvis jr stents compared to only 1 neuroform atlas stent, confirming significantly poorer wall conformity.
Analysis of clinical records supports microstent coiling in narrow arteries, though elevated parent artery diameter mismatch ratio warrants careful stent selection.
