Aneurysm of saphenous vein bypass graft to coronary artery

Aneurysmal saphenous vein graft presenting as an anterior mediastinal mass

“…This case represents a rare and unusual presentation of atherosclerosis of a lbyear-old saphenous vein graft presenting as an anterior mediastinal mass. The severe aneurysmal dilatation of this saphenous vein graft was quite grafts and graft thrombosis are commonly found in autopsy studies [8]. Most cases [ 1,9-131 present 5 to 14 yrs after coronary artery bypass grafting.…”

“…Most cases [ 1,9-131 present 5 to 14 yrs after coronary artery bypass grafting. Two cases occurred within 6 mon of bypass grafting [7,8] and were felt to be secondary to pre-existing vein wall weakness or to unrecognized vascular trauma at the time of harvesting. One case [2] underwent autopsy after sudden cardiac death and the graft had diffuse severe atherosclerosis with multiple aneurysms.…”

Giant Aneurysm of Aortocoronary Saphenous Vein Graft Compressing the Left Pulmonary Artery

“…1,2 In 1975, Riahi et al reported the first case of aneurysm of an aortocoronary saphenous vein bypass graft. 3 Clinical presentation is variable: myocardial infarction due to distal embolization from the venous graft, angina pectoris, atypical chest pain, and the congestive heart failure. Only 12% of the patients are asymptomatic.…”

Intrinsic and Extrinsic Cardiac Pseudotumors: Echocardiographic Evaluation and Review of the Literature

“…In 1975, Riahi and colleagues first described aortocoronary saphenous vein graft aneurysms (SVGAs). 6 SVGA is defined as a localized dilatation of the SVG (saphenous vein graft) more than 1.5 times the proximal reference diameter. 7,8 Although the true incidence is difficult to determine, an incidence of 0.07% was estimated from an extensive review of more than 5500 grafts performed between 1975 and 1991 at a single institution.…”
