Multimodal Biocollection Linked to the French Register of Intracranial Aneurysms
Nantes University Hospital

Conditions
Summary
The purpose of the bCAN study is to create a prospective collection of multimodal data and human samples, linked to the French Intracranial Aneurysm Registry (FRAN). The aim of bCAN is to enable risk stratification of ruptured ICAs by redefining "intracranial aneurysm disease". The description of genotypically and phenotypically specific subgroups of cases will pave the way for improved patient management based on new diagnostic/prognostic strategies among AIC carriers, either in a familial context, or at the level of the general population.
