Abstract
A 59-years-old man was admitted to our hospital because of aneurysmal enlargement around a graft. Two months earlier he had undergone surgical repair of abdominal aortic aneurysm and coronary artery bypass. The patient was operated because of a diagnosis of seroma. The seroma sac was excised for drainage and a pedicled omentum was used to cover the aortic graft to promote healing the interstices of the graft and preventing aortoenteric fistula. The postoperative course was uneventful and the patient is doing well 8 months after the operation. We think this procedure is simple and useful for high risk patients in order to control perigraft seroma.
