FRED-UK: Multicentre UK experience of FRED and FRED Jr flow re-direction endoluminal device for intracranial aneurysms: 6 months and 1 year clinical and anatomical results.

Background: Flow diverting stents (FDS) are an established endovascular treatment for intracranial aneurysms but are reported to have varying rates of adequate occlusion and thromboembolic complications. This study reports clinical safety and efficacy results of the FRED and FRED Jr FDS in clinical practice in the UK at 6 months and 1 year.

Methods: The FRED-UK study is a single arm, multicentre, prospective, observational study conducted in the UK.

Evaluation of flow diverters for cerebral aneurysm therapy: recommendations for imaging analyses in clinical studies, endorsed by ESMINT, ESNR, OCIN, SILAN, SNIS, and WFITN.

Background: Multiple studies and meta-analyses have described the technical and clinical outcomes in large cohorts of aneurysm patients treated with flow diverters (FDs). Variations in evaluation methodology complicate making comparisons among studies, hinder understanding of the device behavior, and pose an obstacle in the assessment of further advances in FD therapy.

Methods: A multidisciplinary panel of neurointerventionalists, imaging experts, and neuroradiologists convened with the goal of establishing consensus recommendations for the standardization of image analyses in FD studies.

Contour Neurovascular System for endovascular embolization of cerebral aneurysms: a multicenter cohort study of 10 European neurovascular centers.

Background: Intrasaccular devices have become increasingly popular in the treatment of cerebral aneurysms, particularly at the bifurcation. Here we evaluate the Contour Neurovascular System, an intrasaccular device for the endovascular treatment of cerebral aneurysms, in a multicenter cohort study, the largest to the best of our knowledge.

Methods: Consecutive patients with intracranial aneurysms treated with the Contour Neurovascular System between February 2017 and October 2022 at 10 European neurovascular centers were prospectively collected and retrospectively reviewed.

Microsnare retrieval as a bail-out technique of Detached Woven EndoBridge device: Illustrative series.

Background: The Woven EndoBridge (WEB) device (MicroVention, Tustin, CA, USA) has an excellent safety profile. While major complications such as device malposition and migration are rare, they can have serious consequences if not addressed promptly. Our case series describes the safety and efficacy of Amplatz goose neck microsnare device (Medtronic in Irvine, CA, USA) in endovascular retrieval of a detached WEB device.
