Early Saphenous Venous Graft Pseudoaneurysm, a Rare Cause of Acute Coronary Syndrome: Too Early or Too Late—A Management Dilemma

A saphenous vein graft (SVG) is a bypass conduit that is frequently employed in surgical revascularization operations. One of the primary issues with SVGs is that they can encounter blockage rates of up to 25% within the first year. Saphenous venous graft aneurysms (SVGAs) are extremely uncommon, yet they can develop at any time. While early SVG degeneration may result in SVGAs, the classic indications of myocardial ischemia are often associated with late SVG degeneration. Other methods of imaging, including coronary computed tomography and graft angiography, can detect SVGA that would otherwise go undetected. This issue may cause mortality to be underestimated, resulting in fatalities that go unnoticed and uninvestigated. The major goal of this case report was to offer a detailed account of an early SVGA episode in a patient who had a documented non-ST-segment myocardial infarction and significant myocardial ischemia, as confirmed by coronary artery angiotomography.
