We sought to determine the safety and feasibility of mechanical thrombectomy using the new ERIC retrieval device.MATERIALS AND METHODS: We identified 36 consecutive patients from our Stroke Center registry with acute ischemic stroke who were treated with the new ERIC retriever from September 2013 to December 2014. Patients with ischemic stroke meeting the following criteria were eligible: onset-to-treatment time of <=4.5 hours or wake-up stroke (n = 10) with relevant CT perfusion mismatch, NIHSS score of >=4, and proof of large-vessel occlusion in the anterior circulation on CT angiography. We assessed the baseline characteristics including age, sex, comorbidities, stroke severity, site of vessel occlusion, presence of tissue at risk, and treatment-related parameters such as onset-to-treatment time, recanalization grade, and outcome.RESULTS: The mean age was 70 {\textpm} 13 years, and the median NIHSS score on admission was 18 (interquartile range, 10{\textendash}20). Seventeen of 36 patients were on platelet inhibitors or anticoagulants before endovascular treatment (47.2\%); 20 patients received intravenous thrombolysis (55.5\%). The ERIC was used as the sole retriever in 28 patients (77.8\%) and as a rescue device in 8. Excellent recanalization was achieved in 30/36 patients (83.3\%) with TICI 3 in 19/36 and 2b in 11/36, respectively. Median procedural time in these patients was 90 minutes (interquartile range, 58{\textendash}133 minutes). No intraprocedural complications occurred.CONCLUSIONS: In this observational study, the new ERIC retrieval device was technically feasible, safe, and effective in acute ischemic stroke with large-vessel occlusion.AbbreviationsERICEmbolus Retriever with Interlinked CagesIQRinterquartile rangeIVTintravenous thrombolysissICHsymptomatic intracerebral hemorrhage}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/early/2015/08/20/ajnr.A4463}, eprint = {https://www.ajnr.org/content/early/2015/08/20/ajnr.A4463.full.pdf}, journal = {American Journal of Neuroradiology} }
