Aspiration of Postmastectomy Seroma

After mastectomy, nearly all patients have a fluid collection (seroma) in the region of the operation wound. A large seroma causes tension of the wound, and should be aspirated with a large bore needle. Ultrasonography before the procedure is not necessary, but if available, it helps to locate the largest fluid collection. The patient sits during the procedure. Take care of sterility. After local anaesthesia, the needle is inserted into lower part of the fluid-filled cavity. Aspirate with syringe or let the fluid flow spontaneously through the needle. Gentle pressure over the seroma hastens the emptying of the fluid. If the fluid is turbid or the patient has symptoms of infection (increased pain, redness of the wound, or fever) bacterial culture of the fluid is indicated.
