ACCESS: ACtive Catheterization for EndovaScular TreatmentS-A First-in-Human, Single-Center, Nonrandomized, Open Clinical Study of the G60 Active Device for Endovascular Neurointerventions.

The catheterization of supra-aortic vessels during neuroendovascular interventions may be challenging in the setting of complex aortic arch anatomy. Evaluation of a new mechatronic controllable directional device in conjunction with different sheath and guide catheters to ease the cannulation of the supra-aortic vessels was conducted in the setting of a first-in-human clinical study. The evaluation assessment included access to the aortic arch, the technical success of the device in terms of time to target vessel, target vessel catheterization, adverse events, and clinical outcome.

Outcome of Aneurysmal Subarachnoid Hemorrhage Not Altered With Transatlantic Airplane Transfer: A Bicentric Matched Case-control Study.

Objective: It is recommended that ruptured cerebral aneurysms are treated in a high-volume center within 72 hours of ictus. We assessed the impact of long-distance aeromedical evacuation in patients presenting aSAH.

Methods: This case-control study compared patients with aneurysmal subarachnoid hemorrhage (aSAH) who had a 6750 km air transfer from Guadeloupe (a Caribbean island) to Paris, France, for neurointerventional management in a tertiary center with a matched cohort from Paris region treated in the same center over a 10-year period (2010 to 2019).

Mechanical thrombectomy in basilar artery occlusions: impact of first-line strategy as a function of the occlusion level.

Background: Retrospective studies suggest the superiority of first-line contact aspiration (CA) thrombectomy over stent-retriever (SR) in basilar artery occlusions (BAO). We aimed to investigate the impact of first-line mechanical thrombectomy per the occlusion level, considering differences in stroke etiology prevalence between proximal and distal BAO.

Methods: A retrospective, multicentric analysis of the Endovascular Treatment in Ischemic Stroke Registry (ETIS) included consecutive BAO patients treated from January 2016 to May 2022.

Long-term outcome of endovascular treatment for indirect carotid-cavernous fistulas.

Objective: Endovascular treatment (EVT) is the primary approach used to treat indirect carotid-cavernous fistulas (CCFs). In this study, the authors evaluated the immediate and long-term efficacy and safety of different endovascular techniques for indirect CCFs.

Methods: The databases of two endovascular centers were retrospectively reviewed to collect the patients with indirect CCFs treated using endovascular techniques between 2013 and 2023.

Embolization of the middle meningeal artery for the prevention of chronic subdural hematoma recurrence in high-risk patients: a randomized controlled trial-the EMPROTECT study protocol.

Background: Middle meningeal artery (MMA) embolization has been proposed as a treatment of chronic subdural hematoma (CSDH). The benefit of the procedure has yet to be demonstrated in a randomized controlled trial. We aim to assess the efficacy of MMA embolization in reducing the risk of CSDH recurrence 6 months after burr-hole surgery compared with standard medical treatment in patients at high risk of postoperative recurrence.
