“…However, angiography is an invasive procedure ordinarily requiring hospitalization and a definite risk of complication is associated with it. Noninvasive or minimally invasive methods for analyzing the functioning of bypass grafts, such as radionuclide ventriculography [2,3], thallium-201 scintigraphy [4], and positron emission tomography [5], are of limited value because they only indirectly assess bypass graft patency. The direct, noninvasive or minimally invasive methods include specific graft identification with MR angiography, digital subtraction angiography, and Doppler sonography.…”

The patency of coronary artery bypass grafts was evaluated by helical computed tomographic (CT) scan. One hundred forty patients who received an enhanced chest CT scan and a coronary angiography after bypass surgery were studied before discharge at the Fukui Cardiovascular Center. Among them was a total of 398 grafts and 436 anastomoses. For the evaluation of 248 vein grafts, the CT scan showed a 99.5% correct positive ratio and an overall accuracy of 96.4%. In 122 internal thoracic arteries tested, an overall accuracy of 64.7% was obtained. In gastroepiploic artery tests the overall accuracy was 33.3% and in radial artery tests it was 45.5%. Thirty‐seven venous sequential anastomoses in 34 grafts and 1 internal thoracic artery sequential anastomosis were also evaluated. In the venous sequential anastomosis, the CT scan showed a 73.0% of accuracy overall. This study showed that the helical CT scan was useful to evaluate graft patency following bypass surgery. Cathet.
