Giant saphenous vein graft pseudoaneurysm to right posterior descending artery presenting with superior vena cava syndrome

Figure 3 Coronary angiography demonstrated a giant pseudoaneurysm of the saphenous vein grafts with patent flow to the right posterior descending art. A: Coronary angiography showing the ostial and proximal right coronary artery (RCA) occlusion; B: Angiographic image depicting the upper lobe of the SVG to RPDA giant pseudoaneurysm; C: Giant pseudoaneurysm of vein graft with wide neck beginning about 2 cm from the graft origin; D: Injection within the aneurysm sac revealing a patent bypass graft that continues into the distal right coronary artery with a sequential connection to the posterior descending artery; E: Computed tomographic 3-D reconstruction of the SVG giant bilobed pseudoaneurysm to the distal right coronary artery seen in relation to the thoracic structures. SVG: Saphenous vein grafts; RPDA: Right posterior descending artery.
