Conventional angiogram and intravascular ultrasound (IVUS) immediately, 25 months, and 50 months after drug-eluting stent (Eluvia) placement. A: Angiography immediately after drug-eluting stent (Eluvia) placement. Angiography showing optimal expansion. B: Angiography 25 months after drug-eluting stent (Eluvia) placement. Angiography showing no significant stenosis or peri-stent contrast staining in the distal part of the right superficial femoral artery. C: Angiography 50 months after drug-eluting stent (Eluvia) placement. Angiography demonstrating peri-stent contrast staining in the distal part of the drug-eluting stent (Eluvia) placement site (red arrow). a-c: Images of IVUS immediately after drug-eluting stent (Eluvia) placement. IVUS demonstrating optimal expansion of drug-eluting stent (Eluvia) (a-c). Maximum vessel diameter was 7.3 mm at the distal edge of the drug-eluting stent (Eluvia) placement site (b). d-f: Images of IVUS 25 months after drug-eluting stent (Eluvia) placement. IVUS revealing vessel enlargement with a maximum vessel diameter of 10.0 mm at the distal edge of the drug-eluting stent (Eluvia) placement site (d-f). g-i: Images of IVUS 50 months after drug-eluting stent (Eluvia) placement. IVUS showing further enlargement of the maximum vessel diameter to 12.0 mm at the distal edge of the drug-eluting stent (Eluvia) placement site (g-i). Enlargement of the lumen and stent malapposition (g and h)
