Initial randomized trials of endovascular thrombectomy focused on large-vessel occlusions. These proximal occlusions of the intracranial carotid artery or the stem of the middle cerebral artery (MCA) represent the most severe form of anterior circulation ischemic stroke. The large clinical benefit from endovascular thrombectomy is consistent with the patent artery hypothesis and reperfusion associated with intravenous thrombolysis. Reperfusion success after endovascular thrombectomy is now routinely achieved in 90% of patients, but early reperfusion, as measured with computed tomographic (CT) angiography at approximately 2 to 4 hours after treatment with intravenous thrombolysis, occurs in only 35 to 40% of patients with large-vessel occlusions and in 50% of those with more-distal medium-vessel occlusions.  aICTUS 954458  aRADIOLOGÍA GENERAL954381  aNEUMOLOGÍA925628  aENFERMEDAD ARTERIAL PERIFÉRICA Y AÓRTICA954459  aNEUROLOGÍA  aGERIATRÍA91852  aMEDICINA DE URGENCIAS 953820  aCUIDADOS INTENSIVOS95208  aHill, Michael D. 9544910 022717922669dMassachusetts NEJM GroupoNEJM014tThe New England Journal of Medicine wESSALUDx0028-4793  cARTICULOSe2026-08-31zsqb  c22909d22909
