title: An unusual complication of minidose heparin therapy.
abstract: A 50-year-old woman developed a massive hematoma of the superficial abdominal wall following subcutaneous heparin therapy. The lesion was located above the fasica, became infected, and was associated with epithelial necrosis over the right lower quadrant of the abdominal wall. Operative excision of the entire affected area with primary closure was successful 4 weeks following the injection. The etiology of this problem was attributed to accidental laceration of the superficial epigastric vessels. This extensive local complication of subcutaneous minidose heparin injection seems not to have been previously reported.
