Stent-graft deployment to treat a perigraft seroma formed after descending thoracic aortic surgery.

摘要

PURPOSE: To report a case of stent-graft implantation for a perigraft seroma that formed after descending thoracic aortic surgery. CASE REPORT: A 70-year-old woman presented with a perigraft seroma after a descending thoracic aortic surgery 10 years ago in which a polytetrafluoroethylene graft was used. Chest radiography and computed tomography confirmed the presence of a large perigraft seroma. The previous graft was covered with a stent-graft to decrease graft porosity. At 1 year, postoperative examinations revealed a decrease in the size of the perigraft seroma. CONCLUSION: Stent-graft implantation could prove useful in cases of perigraft seromas where additional conventional surgery may pose difficulties.
