Short-term assessment of radial artery grafts with multidetector computed tomography

Abstract Background The clinical use of the radial artery (RA) in coronary bypass grafting (CABG) is still limited worldwide, although it has been recommended by several guidelines. Multidetector computed tomography (MDCT) widely used to evaluate graft patency, as invasive angiography could cause potentially serious risks including bleeding, dissection and stroke. This study aims report short-term results RA CABG with MDCT. Methods population consists 41 consecutive patients undergoing elective between 2017 2018, MDCT performed patency during follow-up, target vessels for were non-left anterior descending arteries > 70% stenosis. Results A total 150 grafts assessed follow-up (mean, 8.9 ± 5.1 months). clearly show structure grafts, even complex revascularization. Graft left internal mammary was 92.9% (39/42), 84.4% (38/45) saphenous vein 81.1% (30/37). And anastomosed system might have better than right (25/29, 86.2% vs 13/16, 81.3%, p = 0.686). Conclusions rate good, be associated when but not artery. provide excellent visualization CABG.
