Endovascular Recanalization for Chronic Symptomatic Intracranial Vertebral Artery Total Occlusion
Figure 3
A 61-year-old man (case 4) with bilateral intracranial vertebral artery (ICVA) total occlusion (a). Following stenting of right ICVA (b), cerebellum hemorrhage due to perforation was found on the postprocedure CT (c). A 71-year-old man (case 7) with the left ICVA total occlusion and the right ICVA severe stenosis (d). D asymptomatic distal dissection and proximal perforation adjacent to the occlusion occurred during the procedure (e). The perforation resolved after balloon occlusion (f). A 37-year-old man (case 8) with the left ICVA total occlusion and the right ICVA severe stenosis (g). Both ICVA were recanalized but in-stent thrombosis occurred on the left ICVA as shown on day 1 after procedure CTA ((h), (i)).
