Abstract
Coronary artery stenting has become an established treatment for symptomatic coronary artery disease. One of the most important variables that determine the successful clinical outcome of coronary artery stent application is the short and long-term patency rate of the stents. So far, conventional coronary angiography has been considered the standard of reference for evaluation of the patency and luminal stenosis of coronary artery stents. However, the main drawbacks of conventional coronary angiography for this purpose include invasiveness, patient discomfort, and risk of complications. A less invasive imaging modality is desirable for evaluation of patients suspected of having instent stenosis or occlusion. The aim of this study was to evaluate multi-detector row CT angiography as a less invasive technique in the assessment of the patency of the coronary arteries stents. This study included 28 patients with 49 coronary artery stents, 9 of them underwent conventional angiography as a gold standard for evaluation of the coronary artery stents. The indications of angiography were unstable angina & to assess stent patency after suspected instent re-stenosis. The mean age of the included patients was 60 with an age range between 50 and 70 years. Male patients were 24 (86%) while females were 4 (14 %).Patients were assessed by MSCT for follow up of their patency.
