Transarterial and transvenous access for neurointerventional surgery: report of the SNIS Standards and Guidelines Committee.

The purpose of this publication is to provide a comprehensive review on the techniques and tools used for vascular access in neurointerventional procedures. Using published literature, we reviewed data on access methods, sites, tools, and techniques for neurointerventions. Recommendations are provided based on quality of data/levels of evidence and, where appropriate, expert consensus.

Randomization of endovascular treatment with stent-retriever and/or thromboaspiration versus best medical therapy in acute ischemic stroke due to large vessel occlusion trial: Rationale and design.

Background: RESILIENT is a prospective, multicenter, randomized phase III trial to test the safety, efficacy, and cost-effectiveness of mechanical thrombectomy as compared to medical treatment alone in patients treated under the less than ideal conditions typically found in the public healthcare system of a developing country.

Methods: Subjects must fulfill the following main inclusion criteria: symptom onset ≤8 h, age ≥18 years, baseline NIHSS ≥8, evidence of intracranial ICA or proximal MCA (M1 segment) occlusion, ASPECTS ≥6 on CT or >5 on DWI-MRI and be either ineligible for or unresponsive to intravenous alteplase. The primary end-point is the distribution of disability levels (on the modified Rankin Scale, mRS) at 90 days under the intention-to-treat principle.

Safety and efficacy of intracranial aneurysm embolization using the "combined remodeling technique": low-profile stents delivered through double lumen balloons: a multicenter experience.

Purpose: Since appearance of the balloon-remodeling technique and stent-assisted coiling, complex aneurysms have been treated successfully by endovascular means worldwide. Although these two techniques have been widely proven, the combination of both traditionally made the procedures more complicated technically. The aim of our study was to determine the technical success, safety, and efficacy of the low-profile stents delivered through double lumen balloons.

LVIS Jr Device for Y-Stent-Assisted Coil Embolization of Wide-Neck Intracranial Aneurysms: A Multicenter Experience.

Background And Purpose: Complex wide-neck intracranial aneurysms are challenging to treat. We report a multicenter experience using the LVIS Jr stent for "Y-stent"-assisted coiling embolization of wide-neck bifurcation aneurysms.

Methods: Seven centers provided retrospective data on patients who underwent Y-stenting.

Dissecting spinal aneurysms: conservative management as a therapeutic option.

Objective: Isolated dissecting spinal aneurysms are rare lesions that pose a therapeutic challenge. We report our experience in the management of four patients with dissecting spinal aneurysms.

Methods: After institutional review board approval was obtained, the neurointerventional databases of the two participating institutions were retrospectively reviewed.

Successful Retreatment of Recurrent Intracranial Vertebral Artery Dissecting Aneurysms After Stent-Assisted Coil Embolization: A Self-Controlled Hemodynamic Analysis.

Background: Intracranial vertebral artery dissecting aneurysms (VADAs) tend to recur despite successful stent-assisted coil embolization (SACE). Hemodynamics is useful in evaluating aneurysmal formation, growth, and rupture. Our aim was to evaluate the hemodynamic patterns of the recurrence of VADA.
