Interdependence of First-coil and Global volume embolization ratios (VERs) calculated by Sim&Size in predicting aneurysm occlusion outcomes.

ABSTRACT: BackgroundCoil embolization is a standard therapeutic approach for intracranial aneurysms. Recurrence risk during follow-up is not negligible, with inadequate packing density identified as a potential risk factor. This study aims to identify patient- and procedure-related factors contributing to recurrence.MethodsWe retrospectively enrolled consecutive patients with unruptured intracranial aneurysms treated only with coils between January 2021 and December 2022. Aneurysms were included if 3D-rotational angiography and follow-up imaging were available. For each patient, the volume embolization ratio (VER) was computed using Sim&Size^® (Sim&Cure, France) for both the framing coil (First-coil VER) and the entire coiling procedure (Global VER).
