Figure 1 Transaxial tomographic views showing the right coronary artery origin and the saphenous vein grafts pseudoaneurysm lobes. A: The more cranial lobe of the pseudoaneurysm measured 4.7 cm × 5.4 cm in diameter and demonstrated mural thrombosis; B: The caudal lobe of the pseudoaneurysm also demonstrated mural thrombosis and measured 8 cm × 7 cm in its larger diameter; C, D: The caudal lobe of the giant pseudoaneurysm was patent and demonstrated flow into the distal right coronary and right posterior descending artery; E: Computed tomographic 3-D reconstruction of the saphenous vein grafts giant bilobed pseudoaneurysm to the right posterior descending artery.
