Abstract
Background: To describe technical features and initial results of a novel large-bore reperfusion catheter as first thromboaspiration approach for endovascular stroke treatment in terminal internal carotid artery (T-ICA) occlusions.Methods: All patients treated with A Direct Aspiration first-Pass Technique (ADAPT) using JET 7 "Standard Tip" Penumbra Reperfusion catheter for acute T-ICA occlusion were retrospectively included in the study. Baseline data, puncture to recanalization time, number of attempts, switch to second device/technique rate and successful recanalization rate were assessed. Successful recanalization was defined by a thrombolysis in cerebral infarction (TICI) score ≥ 2b and favorable functional outcome was defined according to modified Rankin scale (score, 0-2). Catheter specifics and thromboaspiration reperfusion technique with JET 7 were reported.Results: A total of 21 patients who underwent ADAPT with JET 7 Reperfusion catheter were enrolled for the final analysis. ADAPT was performed as first approach in all cases (100%). First attempt successful recanalization (eTICI ≥2b) was obtained in 90,5% of cases. Mean puncture to recanalization time was 16 minutes. Final successful recanalization was reached in 96.5%. Functional independence at 90 was achieved in 57,1% cases. Symptomatic intracranial hemorrhage occurred in one patient within 24 h.Conclusion: The large-bore JET 7 reperfusion catheter could be considered as first-line in patients with acute T-ICA occlusion, allowing rapid recanalization and low rate of rescue therapy with stent retriver. Further series and/or trial evaluation are required to confirm our results. [ABSTRACT FROM AUTHOR]
