Endovascular Recanalization for Chronic Symptomatic Intracranial Vertebral Artery Total Occlusion
Figure 1
A 62-year-old man (case 3) with right intracranial vertebral artery (ICVA) total occlusion and tandem occlusion of the V3 by CTA (a) and DSA ((b), (c)). Contralateral severe stenosis of the V4 and tortuosity of the V1 were confirmed by CTA (a). The lesion was predilated with a 2 × 20 mm Invatec balloon and covered with a 3 × 18 mm Apollo stent for the V4 and a 3 × 15 mm Apollo stent for the V3 ((d), (e)). A 24-month CTA follow-up showed patency of the right V3 and V4 without in-stent stenosis (f).
