A 74-year-old woman with 90% restenosis at the origin of the right internal carotid artery (ICA), demonstrated by ultrasound, was admitted to our institute in May 2006 for redo percutaneous transluminal angioplasty (PTA) and stenting. She had already undergone carotid endarterectomy (May 2005) and digital subtraction angiography (DSA) followed by carotid stenting (September 2005) at a different hospital for a right internal carotid artery stenosis (>90%) and restenosis (>85%), respectively (Fig. 1). Careful examination of the previous DSA revealed the presence of two bare stents which were only minimally overlapping . Specifically, a 6–8 × 30-mm Protegè and a 7 × 30-mm Wallstent had been deployed in the ICA, with complete resolution of the stenosis (Figs. 2a and 2b).

(a) Following deployment of two stents, the control angiogram shows complete resolution of the stenosis. The two stents are minimally overlapping. (b) DSA (mask image) shows that the stent overlap (between lines) is precariously minimal
