Abstract

ABSTRACT
Background: The recently developed 128 row multidetector CT had made a revolution in coronary artery bypass grafts
(CABG) patency evaluation due to high temporal and spatial resolution beside it is being non invasive.
Subjects and Methods: 50 patients were enrolled for ECG gated CT of coronary arteries bypass grafts between January 2015
and May 2017.
Patients underwent conventional coronary angiography within 2 weeks of MDCT exam. Administration of beta blocker and
nitroglycerin was done prior to CT exam. Breath hold training was mandatory.
Results: 46 grafts were arterial and 74 were venous. 36 of the arterial grafts (78.2 %) were patent, 6 (13 %) were significantly
narrowed and 4 (8.8 %) were completely occluded. Regarding venous grafts, 52 (70.2 %) of them were patent, 14 (19 %) were
significantly narrowed and 8 (10.8 %) were completely occluded. CT angiography compared to the conventional angiography
as a gold standard technique gave us a sensitivity of 100%, a specificity of about 98% and an accuracy of about 93.6% in the
assessment of any type of coronary artery grafts.
Conclusion: MDCT is considered the imaging modality of choice at the current days to evaluate the patency and stenosis of
coronary artery bypass grafts than the conventional coronary angiography due to its multiple drawbacks.
