Second-dose intravenous thrombolysis with tenecteplase in alteplase-resistant medium-vessel-occlusion strokes: A retrospective and comparative study.
Introduction: In intracranial medium-vessel occlusions (MeVOs), intravenous thrombolysis (IVT) shows inconsistent effectiveness and endovascular interventions remains unproven. We evaluated a new therapeutic strategy based on a second IVT using tenecteplase for MeVOs without early recanalization post-alteplase.
Patients and methods: This retrospective, comparative study included consecutively low bleeding risk MeVO patients treated with alteplase 0.9 mg/kg at two stroke centers. One center used a conventional single-IVT approach; the other applied a dual-IVT strategy, incorporating a 1-h post-alteplase MRI and additional tenecteplase, 0.25 mg/kg, if occlusion persisted. Primary outcomes were 24-h successful recanalization for efficacy and symptomatic intracranial hemorrhage (sICH) for safety. Secondary outcomes included 3-month excellent outcomes (modified Rankin Scale score of 0-1). Comparisons were conducted in the overall cohort and a propensity score-matched subgroup.
Results: Among 146 patients in the dual-IVT group, 103 failed to achieve recanalization at 1 h and of these 96 met all eligible criteria and received additional tenecteplase. Successful recanalization at 24 h was higher in the 146 dual-IVT cohort patients than in the 148 single-IVT cohort patients (84% vs 61%, p < 0.0001), with similar sICH rate (3 vs 2, p = 0.68). Dual-IVT strategy was an independent predictor of 24-h successful recanalization (OR, 2.7 [95% CI, 1.52-4.88]; p < 0.001). Dual-IVT cohort patients achieved higher rates of excellent outcome (69% vs 44%, p < 0.0001). Propensity score matching analyses supported all these associations.
Conclusion: In this retrospective study, a dual-IVT strategy in selected MeVO patients was associated with higher odds of 24-h recanalization, with no safety concerns. However, potential center-level confounding and biases seriously limit these findings' interpretation.
期刊介绍：
Launched in 2016 the European Stroke Journal (ESJ) is the official journal of the European Stroke Organisation (ESO), a professional non-profit organization with over 1,400 individual members, and affiliations to numerous related national and international societies. ESJ covers clinical stroke research from all fields, including clinical trials, epidemiology, primary and secondary prevention, diagnosis, acute and post-acute management, guidelines, translation of experimental findings into clinical practice, rehabilitation, organisation of stroke care, and societal impact. It is open to authors from all relevant medical and health professions. Article types include review articles, original research, protocols, guidelines, editorials and letters to the Editor. Through ESJ, authors and researchers have gained a new platform for the rapid and professional publication of peer reviewed scientific material of the highest standards; publication in ESJ is highly competitive. The journal and its editorial team has developed excellent cooperation with sister organisations such as the World Stroke Organisation and the International Journal of Stroke, and the American Heart Organization/American Stroke Association and the journal Stroke. ESJ is fully peer-reviewed and is a member of the Committee on Publication Ethics (COPE). Issues are published 4 times a year (March, June, September and December) and articles are published OnlineFirst prior to issue publication.
