Description

<p>A-76-year-old man with an abdominal aortic aneurysm measuring 55 mm in diameter underwent replacement of his abdominal aorta with a Y-shaped Gelsoft graft. His postoperative course was uneventful. Computed tomography performed five years after the operation showed no remarkable changes, and he subsequently was lost to follow-up. Seven years and eight months after the operation, he was referred to us because of huge seroma around the aortic graft associated with right hydronephrosis, which was detected by computed tomography performed at another hospital. Replacement of the graft with a Triplex graft resulted in remission of both the seroma and hydronephrosis. Although the resected graft was not structurally damaged, vascular wall organization around the graft was very poorly developed. We found a few other cases of the late onset of perigraft seroma after vascular graft implantation in the literature, so we emphasize the necessity of long-term follow-up in such patients.</p>
