Effective Salvage Surgery of a Severely Congested Propeller Perforator Flap Using a Postoperative Delay Technique and Negative-Pressure Wound Therapy

Wound edge–based propeller perforator flaps have often been applied to soft tissue reconstruction of sacral pressure sores. Although this flap often causes necrosis due to overtension and twisting of the perforators, salvage surgery using a postoperative delay technique has not been reported thus far. In this article, we present a case in which we successfully reconstructed a sacral pressure sore using a wound edge–based propeller perforator flap. The flap caused severe congestion, which had a concern due to the potential wide-ranging flap loss; it was subsequently salvaged by an emergent delay procedure and negative-pressure wound therapy on day 2 postoperatively.
