Very late sirolimus-eluting stent thrombosis due to stent fracture and late-acquired incomplete stent apposition detected on multislice computed tomography.

摘要

A 71-year-old man with hypertension, hyperlipidemia and diabetes mellitus was referred for coronary angi-ography (CAG) following an episode of chest pain on exertion. CAG showed a significant stenosis in the middle segment of his left anterior descending (LAD) coronary artery, which was treated with 2 overlapped sirolimus-eluting stents (SESs; 3.5x23mm and 3.0xl8mm) on 25 August 2005 (Figures A,B). Intravascular ultrasound (IVUS) immediately after SES implantation confirmed a well-expanded stent that was not in incomplete apposition (Figure C).
