| Summary: | Purpose The balloon-stent technique (BST) has certain strengths as an assisted technique for
the treatment of complex aneurysms. After Atlas release, the BST can be executed without an
exchange maneuver of the balloon to the stent-delivery catheter. The purpose of this article is
to share our experience with the BST using the Scepter-Atlas combination.
Materials and Methods Device inspection led us to a simple method to avoid failure in loading
Atlas to the Scepter. From March 2018 to December 2019, 57 unruptured distal internal carotid
artery (dICA) aneurysms were treated with coil embolization; among which, 25 aneurysms in 23
patients were treated with BST. Clinical and angiographic data were retrospectively collected
and reviewed. Results The technical success rate of the Scepter-Atlas combination increased from 50% to 100% after
careful inspection. BST angiographic results were comparable to the stent-assisted coil (SAC)
group treated during the immediately post-embolization same period (modified Raymond-Roy classification
[MRRC] 1 & 2 84% in BST, 96.3% in SAC) and during short-term follow-up (MRRC 1 & 2 95.8% in
BST, 88.4% in SAC). A small number of patients showed periprocedural complications, but none had
clinical consequences.
Conclusion BST using the Scepter-Atlas combination can provide an effective and safe method for
the treatment of dICA aneurysms. Scepters can be used as delivery catheters for Atlas.
