Purpose: To determine technical feasibility and results of stent-assisted coiling of visceral artery aneurysms (VAAs) with self-expandable LEO PLUS neurointerventional stent.
Materials And Methods: In this retrospective study, 11 consecutive patients (mean age 61.9 y ± 8.9; range, 45-76 y) with VAAs (splenic, n = 3; common hepatic, n = 2; renal, n = 5; celiac, n = 1) treated with neurointerventional stents were included. MR angiography was evaluated for aneurysmal occlusion and patency of the parent arteries.
Results: Technical success was 90.9%. A minor technical complication developed in 1 patient (9%), and thrombosis of the distal part of the stent was seen just after deployment in another patient, but it resolved after tirofiban injection. Complete occlusion was determined in all patients on MR angiography at 6-month follow-up.
Conclusions: Self-expandable LEO PLUS neurointerventional stents could become a useful tool in the treatment of VAAs. Studies with larger groups of patients, including control groups, are needed to assess the true outcome of this treatment method.

Distal Access Catheter Improves Balloon Guide and Stent Retriever Thrombectomy Outcomes in Nonagenarians.

Neurointerventional Department CDI, Hospital Clinic de Barcelona, Barcelona, Spain.
Background And Purpose: The safety and effectiveness of endovascular techniques in elderly patients with large vessel occlusion (LVO) remain controversial. We investigated the angiographic and clinical outcomes of nonagenarians treated with different endovascular techniques using a balloon guide catheter (BGC), distal aspiration catheter (DAC), and/or stent retriever (SR).
Methods: We analyzed the data from the Registry of Combined versus Single Thrombectomy Techniques (ROSSETTI) of consecutive nonagenarian patients with anterior circulation LVO and compared the outcomes of those treated with BGC+noDAC+SR (101-group), BGC+DAC+SR (111-group), and noBGC+DAC+SR (011-group).
The Artisse Intrasaccular Device: A New Intrasaccular Flow Diverter for the Treatment of Cerebral Aneurysms.

From the Institute of Neurointervention (C. Hecker, C. Hufnagl, A.O., C.J.G., M.K-O.), Paracelsus Medical University, Salzburg, Austria
Background And Purpose: This animal study was designed to evaluate in vivo the acute and short-term safety and efficacy of the new Artisse intrasaccular device (ISD) for aneurysm occlusion and to gain knowledge about the behavior in the aneurysms.
Materials And Methods: The device was implanted in 7 white New Zealand rabbits with bifurcation aneurysms. Immediate and 90-day angiographic follow-up as well as histologic and scanning electron microscope imaging were evaluated.
Managing thrombosis risk in flow diversion: A review of antiplatelet approaches.
Neuroradiol J
January 2025
Department of Radiology, Montefiore Medical Center, Albert Einstein College of Medicine, USA.
Flow diversion is a transformative approach in neurointerventional surgery for intracranial aneurysms that relies heavily on effective antiplatelet therapy. The ideal approach, including the timing of treatment, the use of dual antiplatelet therapy (DAPT), and the number of flow-diverter devices to use, remains unknown. DAPT, which combines aspirin with a thienopyridine like clopidogrel, prasugrel, or ticagrelor, is the standard regimen, balancing thromboembolic protection and hemorrhagic risk.

Objective: In recent years, the application of robotic assistance in diagnostic and therapeutic endovascular neurointerventional procedures has gained notable attention. In this systematic review and meta-analysis, we aim to evaluate the feasibility, safety, and current indications of robotic-assisted neurointerventions and to assess the degree of robotic assistance and reasons for unplanned manual conversion from robotic assistance.
Methods: We searched Medline, Scopus, Web of Science, and Cochrane Library databases following PRISMA guidelines and included studies with ≥ 4 patients reporting on robotic-assisted neurointerventions.
Association between perforator stroke after middle cerebral artery elective stenting and arterial remodeling patterns: a high-resolution MRI-based retrospective cohort study.

Department of Neurointervention, the First Affiliated Hospital of Zhengzhou University, Henan Provincial Neurointerventional Engineering Research Center, Zhengzhou, China.
Background: Patterns of arterial remodeling may be associated with outcomes in patients with severe middle cerebral artery (MCA) stenosis after endovascular treatment (EVT). This study aims to investigate the potential correlation between arterial remodeling patterns in patients with severe MCA stenosis, and plaque characteristics and procedure-related perforator stroke (PS).
Methods: Consecutive patients with MCA atherosclerotic disease who underwent EVT at the First Affiliated Hospital of Zhengzhou University from January 2018 to June 2023 were retrospectively enrolled in this study.
