MT, Mechanical Thrombectomy; mTICI, Modified treatment in cerebral ischemia; NIHSS, National Institutes of Health Stroke Scale; sICH, symptomatic intracerebral hemorrhage; ECASS III, European Cooperative Acute Stroke Study. Technical characteristics (technical thrombectomy attempt) did not have a significant influence on first-pass success, successful recanalization, complete recanalization, post treatment parenchymal hemorrhage and post treatment sICH (all values p > 0.05).
