N2 - BACKGROUND AND PURPOSE: Recent reports have indicated that mechanical thrombectomy may have potential to treat acute ischemic stroke. However, few comparative studies of neurothrombectomy devices are reported. This study aims to compare the safety and effectiveness of two retrievable stent systems in acute ischemic stroke patients. METHODS: A prospective study comparing the clinical, radiological, and functional outcome of 33 patients with an angiographically verified occlusion of the anterior cerebral circulation. Patients were treated either with Trevo RetrieverTM or Solitaire StentTM according to the neurointerventionalist preference. Successful recanalization was defined as TICI grade 2a to 3. Good outcome was defined as a modified Rankin Scale score ≤ 2 at 3 months. RESULTS: Revascularization was achieved in 10 patients (77%) in the Trevo group and in 12 (60%) of the Solitaire group (P = .456). Rate of symptomatic ICH was 0% for Trevo versus 15% for Solitaire (P = .261). Four patients (30%) died during the 3-month follow-up period in the Trevo versus 5 patients (25%) in the solitaire group (P = 1.000). Rate of good outcome was 38% and 40% for Trevo and Solitaire respectively (P = .435). CONCLUSIONS: Our study showed no significant differences between both stentrievers. Moderately high recanalization rates are possible with both, however larger series may depict safety-related variations. © 2012 by the American Society of Neuroimaging.
