Abstract:
Whether the time from intravenous thrombolysis (IVT) to endovascular treatment (EVT) in patients with acute ischemic stroke has an effect on the functional outcome is unknown. Methods The Endovascular Treatment in Ischemic Stroke (ETIS) registry is an ongoing, prospective, multicenter, observational study that perform EVT in France. Data were analyzed from patients treated by IVT and EVT between October 2013 and December 2018 in 6 comprehensive stroke centers. In the primary analysis, we assessed the association of time from IVT administration to start of EVT with functional outcome (measured with the modified Rankin Scale [mRS]), by means of ordinal logistic regression. Secondary end points included angiographic and safety outcomes. Results We analyzed 1,986 patients with acute ischemic stroke due to anterior circulation large vessel occlusion who underwent IVT and EVT. An increased IVT to start of EVT time was associated with a worse functional outcome at 90 days (mRS = 0–2, adjusted odds ratio [OR] per 30 minutes increase in time = 0.91, 95% confidence interval [CI] = 0.86–0.96; mRS = 0–1, adjusted OR per 30 minutes increase in time = 0.89, 95% CI = 0.84–0.94), a lower chance of modified Thrombolysis in Cerebral Infarction (mTICI) grade 2b to 3 reperfusion (adjusted OR per 30 minutes increase in time = 0.93, 95% CI = 0.87–0.98), and an increased probability of symptomatic intracerebral hemorrhage (adjusted OR per 30 minutes increase in time = 1.09, 95% CI = 0.99–1.18). Interpretation These findings provide a basis for further studies to determine if the functional outcome of patients with stroke can be greatly improved by optimizing IVT to EVT times.
