Isotropic half-millimeter angiography of coronary artery bypass grafts with 16-slice computed tomography

Visualisation of non-invasive coronary bypass imaging: 4-row vs. 16-row multidetector computed tomography

“…Therefore, a precise patient history and detailed information on the grafting performed is crucial for a proper evaluation. Dewey et al report on 75 bypass grafts they evaluated, of which 99% of the distal anastomoses were described as eligible for assessment [29]. However, in our results visualization of the distal anastomosis was equal in both groups.…”

Current Status and Clinical Applications of Cardiac Multidetector Computed Tomography

“…Bypass grafts are well shown by MDCT [26,89,90,91,92,93,94,95,96,97]. Saphenous vein grafts are usually larger than the native coronary arteries and move less with cardiac motion than the native vessels.…”

“…6). Feasibility of assessing distal anastomosis has been reported for 74% [93], 94% [26] and 99% of grafts [90]. Distal to the anastomosis, the coronary vessel may be relatively small and more difficult to assess for significant narrowing.…”

Angiografia coronariana minimamente invasiva através de tomografia com múltiplos detectores

“…Various authors [21][22][23][24][25][26][27][28] have studied patients who had undergone surgical revascularization using multislice CTs. The angio-CT technique proved to be precise for the evaluation of various types of anastomosis and coronary artery bypass grafts (fi g.5), in various locations, in patients that were asymptomatic or had angina symptoms.…”
