Drawings summarizing true M1 and M2 occlusions. A, M1 occlusion; B, superior M2 occlusion; C, inferior M2 occlusion; D, M2 trifurcation occlusion. ACA indicates anterior cerebral artery.

Fig 4.
Drawings summarizing “M1-like” occlusions. A, Occlusion of both branches after MCA division, short M1 segment; B, occlusion of both branches after MCA division, distal to the MCA's genu; C, occlusion of both branches of a duplicated or accessory MCA; D, occlusion of either the superior or inferior division of the MCA if it is a dominant branch (ie, division branch feeding ≥75% of the MCA's cortical territory). ACA indicates anterior cerebral artery.
Fig 5.
Fig 5.
Drawings summarizing “M2-like” occlusions. A, Occlusion of 1 branch after MCA division, proximal (short M1 segment) or distal to the MCA's genu; B, occlusion of 1 branch of a duplicated or accessory MCA; C, occlusion of the anterior temporal artery if its trunk is large (ie, as big as M2). ACA indicates anterior cerebral artery.
