Multidetector CT and coronary artery bypass grafts.
The aim of this review is to provide--starting from anatomical, surgical and pathophysiological data--elements for evaluating the status of coronary artery bypass grafts with multidetector computed tomography (CT), taking into consideration the most common conduits used (left and right internal mammary arteries, saphenous vein, radial artery, gastroepiploic artery) and early and late complications (stenosis or obstruction, vasospasm, aneurysms and pseudoaneurysms, malposition). Some of the major problems regarding the examination technique and image analysis are also discussed. Finally, we offer general guidelines for reporting the examination results.
