    In addition to appropriate wound debridement and           71 year old male with a long-standing history of DVT,

    Presented here is a severe venous ulcer case in a
    morbidly obese patient with history of DVT. This
    wound was successfully treated on an outpatient
    basis during weekly local wound care visits, using a
    combination of Cutimed® Sorbact® WCL (Wound
    Contact Layer) and Comprifore multi-layer com-
    pression wraps.

    Cutimed® Sorbact® WCL is a unique bacteria-bind-
    ing dressing coated with DACC (Dialkyl carbamoyl
    chloride), a fatty acid derivative that is highly hydro-
    phobic. When the outer membranes and cell walls
    of pathogenic microbes, which are also hydropho-
    bic, come in contact with DACC, the microbes
    become physically bound to the dressing, unable
    to reproduce, and are removed with each dressing
    change, which helps reduces the risk of wound
    infection. As DACC is a fatty acid derivative, it is
    not an anti-septic, antibiotic, or silver-containing
    product, and has not been linked to any develop-
    ment of resistant bacteria strain or allergic reaction
    to a particular chemical or metal.

    The Comprifore multi-layer compression system is
    a 4-component dressing kit that provides sustained
    graduated compression of 40 mmHg up to 7 days,
    indicated for the treatment of venous leg ulcers.

    Treatment history

     1a                                                       1b

     Day 1 (initial visit)
     The patient presented with large venous leg ulcer, with copious sero-sanguinous exudate with slight odor.
     The wound was debrided, and the wound base was also sharply debrided with #10 scalpel, followed by
     saline irrigation using 35 kHz ultrasound device (Quostic system by Arobella Medical) for 5 minutes.

     After debridement, the wound base was covered mostly with moist red granular tissue with some yellow
     fibrotic tissues. This wound was a full skin thickness ulcer. The peri-wound skin was red and inflamed,
     with brawny skin texture, and mild cellulitis. The wound was cultured, and the patient was given empiric
     antibiotics, Oral Doxycycline 100 mg BID for 2 weeks. The wound dressing at this visit consisted of
     Cutimed® Sorbact® WCL, followed by an ABD pad and Comprifore multi-layer compression wraps for
     edema reduction.

                                                             The patient returned for the review of wound cul-

                                                             was instructed to continue with Doxycycline until
                                                             the prescription was finished.
                                                             The wound was debrided, irrigated and dressed
                                                             with Cutimed® Sorbact® WCL and Comprifore

                                                             the clinic 2-3 times per week, as the wound
                                                             drainage was fairly copious.

                                                             The wound size diminished, and the leg edema
                                                             was much improved. The wound odor was resolved
                                                             by Day 8 and the patient also reported a gradual
                                                             reduction in wound pain and drainage. The wound
                                                             was sharply debrided with a #15 scalpel, followed
                                                             by 35 kHz ultrasound saline irrigation treatments.
                                                             The wound dressing consisted of the same regi-

                              The wound size and leg edema improved steadily
                              at each visit. The wound was again debrided
                              sharply and treated with 35 kHz ultrasound saline
                              irrigation. The same dressing regimen was continued
                              using Cutimed® Sorbact® WCL and Comprifore.

                              Due to the patient’s travel schedule out-of-state,
                              there was a 3-week hiatus of the wound care
                              center visits. The wound treatment was resumed
                              on Day 63, using sharp debridement, followed by
                              35 kHz ultrasound saline irrigation, as well as
                              wound dressing using Cutimed® Sorbact® WCL

                                                          The wound was completely healed on Day 114,

                                                          point, the patient was prescribed prescription
                                                          compression stockings of 20-30 mmHg and was
