CTICasesEnlarging Saphenous Vein Graft Pseudoaneurysm

Imaging findings
A 'bump' was noted on imaging in 2004 following a coronary artery bypass graft (CABG). Follow-up imaging eleven years later demonstrated significant enlargement of this lesion. A CT confirmed contrast flowing through the graft, into an aneurysm or pseudoaneurysm, and then continuing distally.
Key takeaways
An extra 'bump' identified in the setting of a coronary artery bypass graft (CABG) should raise suspicion for a saphenous vein graft (SVG) pseudoaneurysm. These lesions can slowly enlarge over many years and require surveillance to monitor for complications such as rupture or compression of adjacent structures.
