Long-term coronary artery graft patency evaluation by computed tomographic coronary angiography

Aamena Ali, Shazia Yusuf, Shazia Zeb, Romasa Zeb, Uswa Zeb.

Abstract
Objective: To evaluate long-term coronary graft patency post coronary artery bypass graft (CABG) surgery in coronary artery disease (CAD) patients using 64-slice coronary computed tomographic angiography (CCTA).
Methodology: In this retrospective study, a total of 11 CAD patients with history of CABG were included. All patients had CCTA at least 5 years after CABG. Patency rates for both arterial and venous grafts were calculated.
Results: Out of 11 patients with a total of 29 grafts, comprised of 9 left internal mammary artery (LIMA) grafts and 20 saphenous vein grafts (SVGs). Overall, 62.06% grafts were patent, 37.93% showed disease, including 2 (18.18 %) arterial and 9 (81.81 %) venous grafts. The patency rate for LIMA grafts was 77% and SVGs was 55%.
Conclusion: The LIMA grafts showed significantly higher long-term patency rate than SVG, 5 years after CABG.

Key words: Atherosclerosis, occlusion, tomography.
