Use of Tenecteplase in Acute Ischemic Stroke in the Time of SARS-CoV-2.

Tenecteplase (TNK) is a fibrinolytic drug that is administrated in a single bolus, recommended in eligible patients with acute ischemic stroke prior to mechanical thrombectomy. This study explores its usefulness in adverse situations, such as the SARS-CoV-2 pandemic. We conducted a retrospective study involving consecutive patients with suspected acute ischemic stroke treated either with intravenous fibrinolysis with alteplase during 2019 or with TNK (.25 mg/kg) between March 2020 and February 2021. A comparative analysis was made to compare patient treatment times and prognosis. A total of 117 patients treated with alteplase and 92 with TNK were included. No significant differences were observed in age, main vascular risk factors or previous treatments. The median National Institutes of Health Stroke Scale was 8 in the alteplase group and 10 in those treated with TNK (P = .13). Combined treatment with mechanical thrombectomy was performed in 47% in the alteplase group and 46.7% in the TNK group; Thrombolysis In Cerebral Infarction scale 2b-3 recanalization was achieved in 83% and 90.7%, respectively (P = .30). There was a decrease in onset-to-needle median time (165 min vs 140 min, P < .01) and no significant variations in door-needle median time. There was no significant difference in the incidence of symptomatic hemorrhagic transformation in mortality or functional independence at 3 months. The easier administration of TNK has improved the accessibility of fibrinolytic therapy, even in adverse circumstances, such as the COVID-19 pandemic. Its use appears to be safe and effective, even in patients who are not candidates for mechanical thrombectomy.
