1 Introduction V.A.C. (Vacuum Assisted Closure) Therapy is a system that uses controlled negative pressure (vacuum) to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material. This advanced wound healing therapy can be readily integrated into the clinician s wound healing practice, helping to optimize patient care and manage costs.
