Case Report on Saphenous Vein Graft Aneurysm with Fistula Development to The Right Atrium

Saphenous vein graft aneurysms (SVGA) are rare complications after coronary artery bypass graft (CABG) operation, which can develop fatal complications including cardiac ischemia, compression, rupture, and death. A 72-year-old male patient presented four years post-CABG with dyspnea. Investigations showed a saphenous vein graft aneurysm with fistulization to the right atrium. During the catheterization, the large coronary artery graft aneurysm was seen on the right measuring up to 6.0 x 4.7 x 6.7 centimeters. This was successfully operated by surgical excision and repaired. The patient was eventually discharged home. Commonly SVGAs are asymptomatic, but clinically significant ones are possible and should be diagnosed and treated appropriately.
