Peri-procedural data from mechanical thrombectomy stratified for thrombus age. Numbers are expressed as frequency (percentage) or median (interquartile range).
Success of MT is defined as a TICI 2B score or higher after mechanical thrombectomy.
LVOS, large vessel occlusion stroke; fresh, fresh thrombus (<1 day old); old, old thrombus (>1 day old); rTPA, recombinant tissue plasminogen activator (thrombolysis); time to MT, median time to mechanical thrombectomy in minutes; ICA, internal carotid artery; M1/M2, M1 en M2 segment of the middle cerebral artery; VA, vertebral artery; TICI, thrombolysis in cerebral infarction grading system.
