Overview

Retrospective analysis identifies factors affecting occlusion outcomes in unruptured intracranial aneurysms treated with the Surpass Evolve stent.

Key Points

  • The study found that larger aneurysms are linked to poor occlusion rates, with an odds ratio of 0.89.
  • The overall favorable occlusion rate was 79.4% observed over a mean follow-up of 17.5 months.
  • Multivariate analysis indicated that branch incorporation significantly increases the risk of poor occlusion (OR=8.26).
  • Treatment with the Surpass Evolve stent demonstrated feasibility regarding safety, with very low rates of mortality and morbidity.
