A case of very late stent thrombosis facilitated by drug eluting stent fracture: comparative images before and after stent fracture detected by 64-multidetector computed tomography.
A stent fracture (SF) is one of the responsible factors for in-stent restenosis after a percutaneous coronary intervention. Factors that have an important role for a SF are vessel tortuosity, the presence of a right coronary artery lesion, overlapping stents, and the use of a drugeluting stent (DES) such as a sirolimus-eluting stent. Unlike with the use of bare metal stents, most SFs have occurred with the use of DES, and a DES may be a possible factor for a SF. A SF can cause clinical problems that range from stable angina to acute coronary syndrome. We experienced a case of acute myocardial infarction that was combined with a SF. We describe here the coronary angiography findings and the 64-multidetector computed tomography images before and after the SF.
