PDFAbstract
Objective To explore the different diagnostic value of MSCT angiography (computed tomography angiography, CTA) and digital subtraction angiography(DSA) in the patients with restenosis after coronary stent implantation. Methods Retrospective analysis of 31 cases of coronary stent implantation in patients with CTA postprocessing images were compared with DSA images, observate the stent patency, stenosis and distal vascular. Results 8 cases with restenosis after stent implantation were been found by CTA, 10 cases were confirmed by DSA.The sensitivity was 83%, the specificity was 90%, the positive predictive value was 71% of the CTA examination.There was no significant difference between the CTA and DSA. Conclusion MSCT coronary artery imaging can obtain similar results with DSA.It is important to understand the prediction of in-stent restenosis. The combination of the two examination can be accurately determine and understand the patency of coronary stent and the degree of stenosis.
