Effective Treatment for Recurrent Perigraft Seromas of Upper Arm Polytetrafluoroethylene Grafts: Report of Two Cases

Among the possible complications of hemodialysis polytetrafluoroethylene (PTFE)graft creation, perigraft seromas are rare, but sometimes troublesome. Debridement withdrainage is usually the method of treatment. However, recurrence is not unusual. Herein wedescribe 2 cases of recurrent perigraft seroma treated by a simple but effective surgicalmethod: excision of the pseudocapsule and revision of the arterial inlet.
