[Assessment of coronary artery stents in computed tomography: state of the art].
Percutaneous coronary interventions (PCI) with stent implantation play an important role in the revascularization therapy of coronary artery disease. Introduction of drug eluting stents (DES) diminished problem of restenosis but brought several new major problems like i.e. late stent thrombosis. This makes bare metal stents (BMS) still popular choice for some patients. Coronary-artery-computed-tomography becomes useful device in the noninvasive diagnostics measure of restenosis after PCI. Development of 64-slice computed tomography (CT) enables the noninvasive imaging and evaluation of stents with diameter higher than 3,0 mm and detection of significant restenosis with a low number of false positive results. CT allows with high accuracy to exclude in-stent restenosis among patients with atypical angina, especially those localized in proximal segments of coronary arteries. Future development of CT is needful since evaluation of significant number of examinations remains difficult or impossible due to presence of artifacts.
