Evaluation of Previously Cannulated Radial Arteries as Patent Coronary Artery Bypass Conduits

Timothy Watson et al. Tex Heart Inst J. .

Abstract

In coronary artery bypass grafting, good-quality conduits are needed to maximize the potential for long-term patency. Revascularization has traditionally been achieved with use of the saphenous vein and the internal thoracic arteries. In recent years, total arterial revascularization with use of the radial arteries has been promoted. Meanwhile, use of the transradial approach for coronary angiography has also increased. The long-term effects of previous cannulation in radial artery bypass grafts are not known. Therefore, we used multidetector computed tomographic angiography to investigate radial-artery graft patency in a small series of patients who had undergone transradial angiography. We found a high patency rate, and we discuss those findings here.

Keywords: Coronary angiography/methods; coronary artery bypass/methods; radial artery/transplantation; risk factors; treatment outcome; vascular patency.
