Saphenous vein graft pseudoaneurysm should be considered in the differential diagnosis of a mediastinal mass or suspected right atrial myxoma in patients with a history of CABG, even decades later.
Answers are grounded in this paper and cite their sources.
May warrant including late SVG pseudoaneurysm in post-CABG mediastinal mass differentials; hypothesis-generating for surveillance imaging protocols.
Saphenous vein graft aneurysm is a relatively rare but serious complication of coronary artery bypass grafting (CABG). The diagnosis of such cases is clinically challenging and requires a high index of suspicion, especially if presented atypically or very late after CABG. Herein, we report a case of a saphenous vein graft pseudoaneurysm that presented 36 years after CABG and was masquerading as a right atrial myxoma on serial echocardiograms over a 2-year follow-up period.
