Baseline aneurysm geometry and flow predict Contour device outcomes

In 39 intracranial aneurysm cases treated with the Contour Neurovascular System, smaller pre-treatment dome and ostium areas predicted positive outcome (Cliff δ −0.57 and −0.43); device shape changes correlated with oscillatory flow.

• This retrospective image-based simulation study included 39 CNS-treated intracranial aneurysm cases.
• Aneurysm geometry showed the strongest association with outcome: smaller dome (Cliff δ −0.57) and ostium (δ −0.43) areas were linked to positive outcome.
• Oscillatory flow features were most associated with SM3 shape modification (δ ≈0.56–0.57); exploratory SVM showed limited discrimination (mean AUC 0.57).
