Closed Surgical Incision



  • 45-year-old female.
  • BMI of >35.
  • Breast cancer patient -
    mastectomy with immediate
    breast reconstruction using a
    total latissimus dorsi flap.



  • 21cm surgical wound. Skin closed
    stitched with resorbable
    subcuticular sutures
  • The wound broke down and was
    measured at (L) 6cm x (W) 2cm
    with extensive undermining


Management & Results

  • The Avelle™ NPWT System with the
    12x31cm dressing applied on day 2,
    and the dressing was changed on
    days 5, 7 and 10 postoperatively, at
    which point NPWT discontinued.
  • The wound showed improvement,
    measuring (L) 6cm x (W) 1.5cm,
    exudate in the drain remained
    stable. The wound had dried up;
    dead tissue had been successfully
    debrided and the peri-wound skin
    was less purple.
