comparison of solitaire-fr and trevo-provue thrombectomy in patients with anterior circulation large artery occlusion

Background: recent randomized controlled trials have recommended stentriever thrombectomy as an important modality in treating acute ischemic stroke. objectives: this study compares solitaire-fr (st) and trevo-provue (tv) in terms of their angiographic recanalization rates and clinical outcomes in acute ischemic stroke patients with anterior circulation large artery occlusion. patients and methods: forty-seven patients who underwent stentriever thrombectomy using st or tv were retrospectively reviewed. successful angiographic recanalization was defined as a modified treatment in cerebral ischemia (mtici) score of 2b-3 and a good outcome was defined as a modified rankin scale score (mrs) of 0 - 2 at 3 months. we compared angiographic and clinical outcomes of st- and tv-treated patients. results: twenty-one patients (mean age ± sd: 67.7 ± 13.5 years; 14 men) were treated with st and 26 patients (70.7 ± 9.7 years; 13 men) were treated with tv. there were no differences in baseline characteristics, initial national institute of health stroke scale score, location of occlusion, onset to puncture time, or total procedure time between groups. the rate of successful recanalization and symptomatic intracranial hemorrhage (sich) between st and tv groups were not different. [for st group, mtici 2b-3: 19 (90.55%) and sich: 2 (9.5%); for tv group, mtici 2b-3: 23 (88.5%) and sich: 3 (11.5%)]. good outcomes (mrs 0 - 2) were not significantly different between the groups [st: 10 (47.7%) and tv: 13 (50%); p = 0.81]. conclusion: the two stentriever devices showed similar recanalization rates and clinical outcomes in patients with anterior circulation large artery occlusion.
