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.
Figure 2 Significantly distended neck veins secondary to compression of the superior vena cava by the giant saphenous vein grafts pseudoaneurysm to right posterior descending artery.A: Coronal tomographic views showing upper and lower lobes of the SVG pseudoaneurysm (asterisks); B: Large hematoma (red arrow) is shown compressing the SVC (yellow arrow); C, D, E: Computed tomographic 3-D reconstruction of the SVG giant bilobed pseudoaneurysm and SVC compression (yellow arrow) in anterior, lateral and posterior views. SVG: Saphenous vein grafts; SVC: Superior vena cava.
