A 6-8 x 40 mm tapered open-cell stent (Acculink, Abbott Vascular, IL, USA) was placed at the site of the occlusion and postdilated with a 5 x 20 mm balloon (Viatrac, Abbott Vascular, IL, USA). A completion angiogram confirmed the patency of external carotid artery with no residual stenosis (Figure 1).
