The role of the vacuum-assisted closure therapy in the salvage of venous congestion of the free flap: case report.

Indications for vacuum-assisted closure (VAC) therapy described generally include acute, chronic, traumatic wounds and ulcers. Recent studies related to investigating new applications of VAC therapy have begun to be reported at literature in many aspects. We used this technique in a novel area. A 21-year-old man presented who suffered venous congestion in anterolateral thigh fasciocutaneous flap at the postoperative second day. Following two cycles of VAC therapy, 72 hours later, venous congestion disappeared. Application of VAC therapy to the flap helps removal of excess interstitial fluid because of increased pressure gradients. It seems that VAC therapy is an option in venous congestion when the interstitial pressure rises above capillary pressure.
