Case Study: V.A.C ® therapy management of a complex ventral abdominal wound

Introduction: Vacuum Assisted Closure (V.A.C®) Therapy has become a common wound care practice used in the treatment of surgical wounds, ulcers, skin grafts, burns, diabetic feet & fistulae. With its increasing use, particularly on complex wounds, clinicians sometimes need to adjust how it is used to ensure a positive patient outcome is achieved.

Background: A 65- year old female required a Hartmanns Procedure for a colovaginal fistula secondary to a diverticular perforation.  Complications such as a retracted stoma, wound breakdown and intra-abdominal sepsis lead to a further five surgical operations, resulting in a large ventral defect beneath the open wound. Other factors such as obesity (BMI 36.6kg/m2) and leaking stoma appliances further complicated her management.

Method: The large, irregular surface area of the wound, meant that V.A.C ® therapy was the most ideal option to heal this wound, but the large ventral defect in the abdominal fascia limited the use of high-pressure V.A.C ®, for fear of causing an enterocutaneous fistula. Using clinical judgement, low pressure V.A.C® therapy was initiated.

This case study outlines the challenges encountered when using V.A.C.® Therapy at low pressure suction, and the solutions created for successful wound healing.

Conclusion: By adjusting the application of low-pressure V.A.C ® to this abdominal wound, dressing leakages were prevented and attended to every 48-72 hours on the ward instead of being completed in the operating theatres. Initially it was planned for the patient to have a skin graft to the wound, but the wound healed without this additional surgery.


Bio to come


This conference is proudly hosted by the Australian Association of Stomal Therapy Nurses:

One of the Association's major objectives is the promotion of quality care for a wide range of people with specific needs. These needs may be related to ostomy construction, urinary or faecal incontinence, wounds with or without tube insertion and breast surgery.

Patients/clients across the life span are provided with preventative, acute, rehabilitative and continuing care as required. Another objective is the maintenance and improvement of professional standards in relation to Stomal Therapy Nursing Practice to the highest degree possible. Recognition of the need for and encouragement of the development of specialist expertise in the field of Stomal Therapy Nursing underpins the Standards for Stomal Therapy Nursing Practice.
