Fig 1. A, Pretreatment arteriogram with M1 occlusion and patent ACA. Baseline NIHSS 25. B, Control arteriogram after 45 minutes of IA treatment demonstrates A2 occlusion, with partial M1 recanalization. C, Final arteriogram after IA treatment demonstrates persistent occlusion of the distal left pericallosal artery superimposed on partial filling of the right ACA, complete recanalization of the M1 trunk with TICI 2 perfusion. D–F, A 24-hour CT demonstrates deep, insular, and inferior frontal infarct. MCA infarct extends superiorly (E) toward the distal posterior frontal lateral cortical borderzone and the distal ACA infarct (F).
