ulcerated diverticulitis with peritonitis.
Wound
- Grade 1 dehisced surgical wound.
- Wound measured 22cm in length
at the start of therapy.

- The Avelle™ NPWT System was
applied for a 30-day period with
8 dressing changes. - The wound had significantly reduced

therapy period

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

tissue and 40% slough. - The largest of the 3 wounds
measured approximately 1.5cm x
1.0cm x 0.2cm deep.
Management & Results
- The Avelle™ NPWT System was
started using a 16cm x 16cm
dressing. - After day 11 the wound measured
0.9cm x 0.6cm x 0.1cm with
100% granulation tissue. Avelle™
NPWT System stopped. - On day 15 NPWT was resumed
with the Avelle™ NPWT System

System was stopped and the
wounds had reduced in size by
95% in 26 days.
