Surgical treatment for saphenous vein graft aneurysm without redo sternotomy

Saphenous vein graft aneurysm (SVGA) is a rare complication after coronary artery bypass grafting; however, it may lead to fatal conditions. A redo sternotomy poses a high risk of injury to the patent graft.

A 59-year-old man with chest pain was diagnosed with a giant SVGA (67 mm) anastomosed to the right coronary artery (RCA) and compressing the right atrium. Considering the high risk of injury to a patent graft through the sternum, a surgical procedure was planned without redo sternotomy. Through an upper midline abdominal incision, redo bypass grafting was performed to the distal RCA using the right gastroepiploic artery, followed by resection of the aneurysm using the right anterior lateral thoracotomy approach. The postoperative course was uneventful.

In patients with an SVGA anastomosed to the right coronary system, our surgical strategy may be a useful alternative to redo sternotomy to avoid injury to the patent graft.
