What is Vacuum Assisted Closure (V.A.C.)?

Vacuum-Assisted Closure (V.A.C.), also known as negative-pressure wound therapy, is a noninvasive, active, closed wound management system. It exposes the wound bed to local subatmospheric pressure, promoting wound healing through several mechanisms.

Indications:

1. Wound Types:

   • V.A.C. is used for various wound types, including:
     • Large, open, contaminated wounds.
     • Dehisced surgical wounds (with or without exposed orthopedic implants or bones).
     • Degloving injuries and skin avulsions.
     • Chronic non-healing wounds.
     • Compartment syndrome (e.g., abdominal/myofascial).

2. Benefits:

   • Granulation Tissue Formation: V.A.C. stimulates granulation tissue formation.
   • Reduced Edema: It reduces interstitial edema and inflammatory cytokines.
   • Improved Circulation: V.A.C. enhances circulation while maintaining a moist wound-healing environment.

Procedure:

1. Application:

   • The wound is packed with open-cell polyurethane foam or gauze.
   • An adhesive drape covers the wound.
   • Tubing connects the wound to an adjustable suction device.
   • Negative pressure is applied to the wound bed.

2. Advantages Over Conventional Wound Care:

   • Faster wound healing.
   • Early wound closure.
   • Improved skin graft adherence.
   • Reduced hospitalization time and bandage changes.

Remember that individual cases may vary, and consulting a veterinarian is essential for proper diagnosis and treatment.
