Treatment of Intracranial Aneurysms with the FRED X Flow Diverter Stent: Mid-term Angiographic and Safety Results.

Purpose: The aim of our study was to assess the mid-term efficacy and safety of the FRED X flow diverting stent (FDS) in the treatment of intracranial aneurysms. The FRED X FDS is relatively new with limited data on its longer-term effectiveness and safety profile.

Methods: Patients with intracranial aneurysms treated with the FRED X FDS at two UK centres, between March 2021 and July 2022 with at least 18 months follow-up, were retrospectively reviewed.

A new classification system for the anatomical variations of the human circle of Willis: A systematic review.

The circle of Willis (CoW) is an anastomotic arterial network located on the base of the brain. Studies have shown that it demonstrates considerable anatomical variation in humans. This systematic review aimed to identify and catalogue the described anatomical variations of the CoW in humans to create a new, comprehensive variation classification system.
