Abstract
An 87-year-old man presented with extracranial vertebral artery (VA) occlusion and progressive vertebrobasilar ischemia despite maximal medical management. Cerebral angiography showed left proximal VA occlusion, termination of the right VA at the ipsilateral posterior inferior cerebellar artery, and hypoplastic bilateral posterior communicating arteries. Although the stump of the left VA ostium was not visualized, the distal patent artery was reconstituted via muscular branches from the left subclavian artery (SCA). Endovascular angioplasty with a stent for left VA occlusion was performed. The non-visualized VA ostium was extrapolated from the computed tomography angiography findings of the distal patent VA and the partial calcification of the SCA. The occluded VA was penetrated by the guide wire and revascularized by balloon angioplasty with the stent using the support of a snare wire inserted via the left brachial artery for stabilization of the guide catheter. This treatment resulted in resolution of the severe neurological findings.
