Case studies

The case studies below are examples of how the PICO sNPWT System delivers the effectiveness of NPWT when used on various wound types. See how the simplicity of the revolutionary PICO sNPWT System may promote positive outcomes and patient mobility.

PICO sNPWT is appropriate for:

  • Acute wounds
  • Chronic wounds
  • Closed surgical incisions
  • Traumatic wounds
  • Sub-acute and dehisced wounds
  • Flaps and grafts
  • Partial-thickness burns
  • Ulcers – diabetic, pressure 

Diverting colostomy

43-year-old male

Underwent emergency laparotomy 2 weeks previously for perforated diverticulitis


open wound

Wound measured 21cm x 2.6cm x 3cm with moderate drainage with no surrounding cellulitis

open wound 2

After 2 weeks of PICO sNPWT application

Knee trauma

73-year-old Caucasian female

with traumatic wound to right knee after falling. Patient had slough and hypergranulation, which required weekly debridements and some silver nitrate.

knee 04

Achieved closure in about 7 weeks with PICO sNPWT


14 days following surgery and after 10 days of RENASYS™ NPWT, treatment with PICO sNPWT was introduced (along with gauze filler). Patient experienced less pain at dressing change with PICO sNPWT.

Diabetic foot ulcer

48-year-old male

with recent amputation of 5th metatarsal and surgical debridement of large Wagner Grade 4 ulcer on right foot. Patient had been using traditional canister-based NPWT for 2 weeks.

foot healing

Day 7: 30% reduction in wound volume; reduction in drainage

wound healed

Closure achieved in part due to approximately 30 days of PICO sNPWT use

Diabetic foot ulcer

82-year-old male

with a past history of diabetes, an myocardial infarction and venous insufficiently having undergone a partial foot amputation 6 weeks earlier following a necrosis and an infection.

After surgery, the wound was treated with MepitelTM dressings prescribed by the orthopedic team for the lower part of the wound and MELOLINTM then protected by TegadermTM. The wound then began to macerate, was foul smelling and painful such that the patient feared another amputation.

The wound was then treated with PICO for 9 weeks. After assessment that the wound was sufficiently closed, it was switched to a traditional treatment.

Skin graft

58-year-old male

with an acute and necroses wound of the dorsum of the foot for which he was hospitalized as an emergency in the dermatology unit, self harm was suspected.

At day +6: the wound was granulating and at skin level. PICO was applied to maintain the graft and to limit the risks from washing over this area on the site.

An interface was positioned between the grafts and the PICO dressing to prevent a possible adherence on removal.

77-year-old male

was being treated for a wound that had failed to heal using conventional wound management therapy for over 1 year. The patient had previously suffered a stroke

The patient was initially treated with RENASYS™ NPWT for 2 months in the hospital to encourage granulation, but in order to allow the patient to be discharged treatment was switched over to PICO sNPWT
