title: Perigraft seroma with minute observations after Gore-Tex graft implantation.
abstract: Perigraft seroma is a very rare postoperative complication following abdominal aortic aneurysm repair. A 74-year-old man with history of esophageal cancer surgery, underwent Gore-Tex graft replacement for an abdominal aortic aneurysm. A 50-mm perigraft seroma was noted one year later, increasing to over 70 mm in the next 6 months. We resected the Gore-Tex graft and replaced it with a Dacron graft via a repeat laparotomy. We observed the resected Gore-Tex graft in detail using electron microscopy to investigate the mechanism of perigraft seroma.
