Summary

A 73-year-old man, who had undergone coronary artery bypass grafting (CABG) 10 days prior, presented with a great saphenous vein graft aneurysm (SVGA). CT revealed the increasing size of the aneurysm. Since the SVGA occurred immediately after CABG and there were no other complications, the aneurysm was treated percutaneously. While intravascular ultrasonography (IVUS) and optical coherence tomography failed to detect the entry point, an IVUS catheter with the addition of ChromaFlo imaging clearly revealed the entry point, size and length of the SVGA. To prevent migration and edge restenosis associated with covered stents, the covered stent (3.0×19 mm) was superimposed on a drug-eluting stent (3.0×28 mm) that covered the entry site. A follow-up study demonstrated the absence of flow into the aneurysm.
