Fig. 3From: Hypergranulation over a meshed split-thickness skin graft, a complication of negative-pressure wound therapy: a case reportPossible mechanism underlying the phenomenon involving covering of the skin graft with granulation tissue. Negative pressure was applied to the healthy granulation tissue through the skin graft interstices, which resulted in the rapid growth of hypergranulation tissue and the formation of a hypergranulation layerBack to article page
