Subintimal recanalization for non-acute occlusion of intracranial vertebral artery in an emergency endovascular procedure: A case report

Figure 5 The subintimal microwire re-entered the true lumen. A: The microcatheter angiography at the level of anterior inferior cerebellar artery (AICA) orifice revealed the true lumen’s position (orange arrow), the AICA branch (the orange dashed arrow), and the subintimal “tubular” dissection (black arrow); B: Under the guidance of a roadmap, the microwire (orange arrows) and the microcatheter (the orange dashed arrows) were manipulated to re-enter the true lumen; C: The microcatheter angiography showed the microwire was advanced to the superior cerebellar artery (orange arrows). AP: anterior-posterior; L: lateral.
