Clinical comparison of intravenous thrombolysis and bridging artery thrombectomy in hyperacute ischemic stroke with unknown time of onset

Abstract

Introduction The aim of the study was to explore the clinical efficacy and safety of intravenous thrombolysis and bridging artery thrombectomy for hyperacute ischemic stroke with unknown onset time. Material and methods One hundred and twenty-eight patients with hyperacute cerebral infarction and without a clear time of onset were randomly divided into intravenous thrombolysis (n = 66) and bridging artery thrombectomy groups (n = 62). Results In the intravenous thrombolysis group, 37 patients’ vessels had recanalization, 32 patients’ 24-hour National Institute of Health Stroke Scale (NIHSS) score improved, and 42 patients’ 90-day modified Rankin Scale (mRS) score was good. In the bridging artery thrombectomy group, 62 patients’ vessels had recanalization, 28 patients’ 24-hour NIHSS score improved, and 38 patients’ 90-day mRS score was good. Conclusions The benefits and adverse events between intravenous thrombolysis and bridging artery thrombectomy for ischemic stroke with unknown time of onset are similar.
