Endovascular treatment of perigraft seroma after open abdominal aortic aneurysm repair: report of a case.

Perigraft seroma is a rare complication after open abdominal aortic aneurysm (AAA) repair. We successfully treated large seroma after expanded polytetrafluoroethylene (ePTFE) aortobiiliac graft repair endovascularly. The patient was an 81-year-old lady with the history of five times laparotomy. She could not take any food because of vomiting. Contrast enhanced computed tomography (CT) revealed giant seroma compressing small intestine. Total relining of the graft with a Excluder(TM) endoprosthesis and open drainage of the seroma was performed. After the surgery, she became asymptomatic and seroma disappeared by CT 2 years later. This modality would be a good option for this rare complication.
