چکیده انگلیسی

BackgroundMost studies have investigated the diagnostic accuracy of 64-slice multi-detector computed tomography (MDCT) to detect coronary artery stent patency by using conventional coronary angiography (CCA) as the reference standard. In this study, we compared the diagnostic accuracy of MDCT and CCA by using intravascular ultrasonography (IVUS) as the reference standard.MethodsForty-six patients with previously implanted coronary artery stents (n = 87) underwent MDCT followed by CCA and IVUS within 24 h. Sensitivities, specificities, positive predictive values (PPV) and negative predictive values (NPV) of MDCT and CCA for detecting or excluding in-stent diameter restenosis (ISDR) by using in-stent area restenosis (ISAR) and minimal luminal area (MLA) ≤ 4.0 mm2 of IVUS as the reference standard were determined.ResultsEight stents (9%) were judged non-evaluable using MDCT for the detection of ISDR. ISDR was detected in 28% (22/79) of the evaluable stents using CCA. When ISAR was detected using IVUS, the sensitivity, specificity, PPV, and NPV for ISDR detection by using MDCT were 71%, 96%, 91% and 86%, and the corresponding values for CCA were 64%, 96%, 90% and 83%. When MLA ≤ 4.0 mm2 was detected using IVUS, the sensitivity, specificity, PPV, and NPV for ISDR detection by using MDCT were 87%, 96%, 91% and 95%, and for CCA were 78%, 96%, 90% and 92%.ConclusionsWhen ISAR with MLA ≤ 4.0 mm2was detected on IVUS, CCA and MDCT had similar diagnostic accuracies for ISDR detection. High specificity and NPV make 64-slice MDCT a reliable non-invasive method for excluding ISDR.
