Background

Time is considered a fundamental driver of treatment success in ischemic stroke reperfusion therapy. First‐pass reperfusion (FPR) is associated with improved outcomes. We explored the association between time to reperfusion, FPR, and functional outcomes in an analysis of the STRATIS (Systematic Evaluation of Patients Treated With Neurothrombectomy Devices for Acute Ischemic Stroke) registry data.

Methods

Registry patients with anterior circulation stroke, treated with endovascular thrombectomy and achieving complete or near‐complete expanded Thrombolysis in Cerebral Infarction scale (eTICI) 2c/3 reperfusion per core laboratory assessment were included. FPR was considered eTICI 2c/3 reperfusion in a single device pass. Patients undergoing multipass …

Background Aspiration thrombectomy devices, such as the AngioVac, allow the removal of thrombus, especially in patients with contraindications to anticoagulation use. The AngioVac was approved by the U.S. Food and Drug Administration to remove fresh, soft thrombi or emboli during extracorporeal bypass for up to six hours. Real-world data on the most common modes of failure and complications associated with the AngioVac are unavailable.

Methods The Manufacturer and User Facility Device Experience database was queried for reports of the AngioVac device failure and adverse events from April 2013 to March 2022. Categorical variables were described as numbers, and all statistical …

Background

A better understanding of real‐world practice patterns in the endovascular treatment for large vessel occlusion acute ischemic stroke is needed. Here, we report the methods and initial results of the Society of Vascular and Interventional Neurology (SVIN) Registry.

Methods

The SVIN Registry is an ongoing prospective, multicenter, observational registry capturing patients with large vessel occlusion acute ischemic stroke undergoing endovascular treatment since November 2018. Participating sites also contributed pre‐SVIN Registry data collected per institutional prospective registries, and these data were combined with the SVIN Registry in the SVIN Registry+ cohort.

Results

There were 2088 patients treated across 11 US …

Background and purpose: The purpose of the COMPLETE (International Acute Ischemic Stroke Registry With the Penumbra System Aspiration Including the 3D Revascularization Device) registry was to evaluate the generalizability of the safety and efficacy of the Penumbra System (Penumbra, Inc, Alameda) in a real-world setting.

Methods: COMPLETE was a global, prospective, postmarket, multicenter registry. Patients with large vessel occlusion-acute ischemic stroke who underwent mechanical thrombectomy using the Penumbra System with or without the 3D Revascularization Device as frontline approach were enrolled at 42 centers (29 United States, 13 Europe) from July 2018 to October 2019. Primary efficacy end points were …

Background It is unknown whether endovascular thrombectomy (EVT) is cost effective in large ischemic core infarcts.

Methods In the prospective, multicenter, cohort study of imaging selection study (SELECT), large core was defined as computed tomography (CT) ASPECTS(CTP) ischemic core volume (rCBF

Results From 361 patients enrolled in SELECT, 105 had large core on CT or CTP (EVT 62, MM 43). 19 (31%) EVT vs 6 (14%) MM patients achieved modified Rankin Scale (mRS) score 0–2 (OR 3.27, 95% CI 1.11 to 9.62, P=0.03) with a shift towards better mRS (cOR 2.12, 95% CI 1.05 to 4.31, P=0.04). Over the projected …
