Management of patients with aortocoronary saphenous vein graft aneurysms. JACC state-of-the-art review

Saphenous vein graft aneurysms (SVGAs) following coronary artery bypass grafting (CABG) surgery were first described in 1975. Although rare, in the absence of a prompt diagnosis, SVGAs can be responsible for serious complications and adverse outcomes. The clinical presentation of SVGAs described in the literature can vary from an asymptomatic patient with an incidental radiological finding to a profoundly shocked patient with life-threatening hemorrhage secondary to SVGA rupture. Improvements in diagnostic tools within the last decade, such as multislice computed tomographic scanning, has enabled early detection of SVGAs, and therefore, an expansion of the current management options. In this review, the current data and knowledge about clinical presentation, diagnosis, natural history, and treatment of SVGAs are updated, with a specific emphasis on the evolution of management strategies of this rare complication over the last 45 years. Finally, a clinical algorithm to guide decision-making and management is proposed.
