Reperfusion of medium vessel occlusions is correlated with good outcomes. However, optimal techniques and medical devices are still unclear. In this study, we sought to evaluate the safety and efficacy of mechanical thrombectomy with Embolus Retriever with Interlinked Cages (ERIC™) retrieval device in patients with acute ischemic stroke due to distal medium vessel occlusions. A retrospective review of the prospectively collected mechanical thrombectomy database revealed 50 patients who had fulfilled the inclusion criteria. The data collected includes clinical patient characteristics, procedural measures, timestamps at each stage, and patient outcomes. Intravenous thrombolytics application, pre- and post-intervention imaging findings, device-related adverse events and any type of intracranial hemorrhage were recorded. There were 25 men (50%) and 25 women (50%) with a median of 67 years (interquartile range (IQR) 41-84). Median presenting NIHSS was 14 (IQR, 3-23). First pass rates were: eTICI3 in 16 cases (32%), eTICI-2c in eight cases (16%), eTICI-2B67 in nine cases (10%), eTICI2B50 in three cases (6%) and mTICI 0-2A in 18 cases (36%). Final recanalization rate of mTICI 2b-3 was 90% and 2c-3 was 70%. In conclusion, the ERIC thrombectomy device offers a high rate of first-pass success along with a favorable safety profile. Larger series and multi-center studies are needed for further investigation.
