Aim: was to evaluate the efficacy of MSCT in assessment of long-term graft patency after coronary artery bypass graft surgery (CABG).

Material and methods: 25 patients with multi-vessel coronary artery disease were included in the research. To assess the 5-year graft patency, MSCT arteriography was performed.

Results: a total of 96 grafts (22 left internal thoracic artery (LITA) and 74 saphenous venous grafts (SVG)) were analyzed using MSCT There were 12 venous sequential grafts and 19 venous Y-shaped grafts determined. During the assessment of graft patency, 13 occlusions of venous grafts and 1 hemodynamically significant stenosis were detected. Occlusion and hemodynamically significant stenosis of mammary grafts were not observed.

Conclusion: MSCT arteriography, allows to determine occlusive and hemodynamically significant stenoses of SVG. Results of study shows the prevalence of SVG occlusions and stenosis over arterial grafts. CT angiography can be highly informative for assessing the patency of grafts in late periods after CABG.
