Dehiscence of infected aortocoronary vein graft suture lines. Cause of late pseudoaneurysm of ascending aorta.

Two cases are described of late pseudoaneurysm of the ascending aorta caused by dehiscence of infected aortocoronary vein graft suture lines. Both cases were associated with early postoperative Staphylococcus aureus superficial wound infection. This complication should be suspected in patients developing protracted wound infections after operation, particularly when associated with rigors.
