A, Right M1 trunk gives rise to the ATA with the posterior temporal branch filling on microcatheter injection. B, Lateral view baseline common carotid arteriogram confirms mid- and posterior temporal lobe cortical supply from the patent posterior temporal artery.
- Fig 2.
A, Anteroposterior: short M1 trunk with no ATA arising is shown. An isolated M2 holotemporal branch originates, simulating and giving origin to the ATA. It then exits the insular cistern, with multiple middle and posterior temporal arteries draping over and supplying the remainder of the temporal lobe (B). B, Lateral view common carotid arteriogram confirms filling of the holotemporal branch, with no other MCA branches filling.

Composite diagram of M1-M2 trunk anatomy based on IMS III post hoc analysis. The M1 trunk proximal to the lenticulostriate arteries (LS) is termed “M1P.” The anterior temporal artery arises from the holotemporal M2 branch (HoT). The M2 trunk is a continuation of the distal M1 trunk, beyond a holotemporal (HoT) or posterior temporal M2 branch. The M2 trunk divides into M2 divisions (M2 Div) or branches. M2 divisions divide further into M2 branches.
