Endovascular treatment of acute ischemic stroke with ERIC device.

BACKGROUND AND PURPOSE: After 6 positive randomized trials, mechanical thrombectomy with stent-retriever is now recommended as a first-line treatment for acute ischemic stroke (AIS). The ERIC device is a device with several interlinked cage-like spheres fixed on a pusher wire. Neurothrombectomy France (NTF) is a registry conducted in France to analyze the results of mechanical thrombectomy. In order to analyze its performances, the subgroup of patients treated with the ERIC device was analyzed.

MATERIALS AND METHODS: NTF is a prospective, multicenter registry dedicated to the evaluation of endovascular treatment for AIS. Primary endpoint was modified Rankin Scale (mRS) at 3months. Secondary endpoints were revascularization at the end of the procedure evaluated with the Thrombolysis In Cerebral Infarction (TICI) scale and rate of procedural complications. Patients treated with the ERIC device were extracted from the NTF registry and analyzed.

RESULTS: From April 2013 to May 2014, 230 patients were included in the NTF registry. Thirty-one patients (13.5%) were treated with ERIC (male: 64.5%; median age: 61years). Median baseline NIHSS was 16. Median ASPECTS was 6. Occlusion location was internal carotid artery (51.6%), middle cerebral artery-M1 (45.2%), and basilar artery (3.2%). Cervical occlusion was associated in 16.1%. Revascularization (TICI 2b-3) was obtained in 87.1%. Good clinical outcome (mRS 0-2) at 3months was obtained in 55.2%. Death rate was 6.9% related to the stroke.

CONCLUSION: This prospective, multicenter series shows good performances of the ERIC device in the treatment of acute ischemic stroke with revascularization in 87.1% and favorable clinical outcome in 55.2%.
