Abstract:
Even though drug-eluting stent (DES) implantation is an effective treatment for coronary artery stenosis, there are growing concerns related to the real usefulness of DESs due to their increased incidence of thrombosis, stent fracture, and late stent malapposition in comparison to bare metal stents. We have previously reported a case of stent fractures and multiple microaneurysms in both the left anterior descending and left circumflex coronary arteries. In the present case, we demonstrate the ability of dual-source spiral computed tomography to evaluate the various complications of DESs.
