BACKGROUND AND PURPOSE The purpose of this study was to examine the efficacy and safety of the 6F Closer S device (Perclose; Redwood City, CA) versus manual compression to close arteriotomy sites after neurointerventional procedures in both virgin vessels and those previously treated with the device. METHODS This single-center, multiple-operator, controlled, prospective study included 475 pro...

Background Increased interest in radiation dose reduction in neurointerventional procedures has led to the development of a method called "spot fluoroscopy" (SF), which enables the operator to collimate a rectangular or square region of interest anywhere within the general field of view. This has potential advantages over conventional collimation, which is limited to symmetric collimation cente...

Endovascular Stroke Training The paper “Performance and Training Standards for Endovascular Ischemic Stroke Treatment” and the accompanying editorial both make the claim that this training standard was approved by the NeuroVascular Coalition. As Founder, first Co-Chair, creator of the name and the abbreviation (NVC), and owner of the Web address (www.neurovascularcoalition.org), I would like to...

BACKGROUND Endoluminal optical imaging, or angioscopy, has not seen widespread application during neurointerventional procedures, largely as a result of the poor imaging resolution of existing angioscopes. Scanning fiber endoscopes (SFEs) are a novel endoscopic platform that allows high-resolution video imaging in an ultraminiature form factor that is compatible with currently used distal acces...

Background We compared technical and clinical outcomes of transradial (TRA) versus transfemoral (TFA) access for mechanical thrombectomy acute ischemic stroke due to large vessel occlusion in the left anterior cerebral circulation bovine origin. Methods A single‐center retrospective review a prospectively maintained neurointerventional database from volume service tertiary academic center. Proc...

Background Two recent trials demonstrated a benefit for endovascular therapy (EVT) in the treatment of basilar artery occlusion (BAO). In light expected increase use EVT BAO, we sought to understand technique preferences neurointerventionalists performing BAO. Methods We conducted an international online survey physician opinions on BAO between January and March 2022. The was distributed throug...

BACKGROUND Human placenta is a convenient resource for biomedical research, and has not yet been used for neurointerventional surgery research. OBJECTIVE Our objective was to explore the feasibility of using human placenta to test various endovascular interventions and for training. DESIGN 18 placentas soon after delivery were prepared for six pilot studies. (1) Study on anatomical similari...
