Vacuum-assisted closure improves the incorporation of artificial dermis in soft tissue defects: Terudermis® and Pelnac®

As a dermal scaffold, artificial dermal substitutes allow the body to accomplish its own tissue regeneration through infiltration of cells and neovascularisation. However, they show not only rather lower take rates compared to autologous skin grafts alone, but they also require more time for sufficient vascular ingrowth to overlay the skin graft. To accelerate this overlaying, we applied vacuum-assisted closure negative-pressure settings over the artificial dermis: Terudermis® and Pelnac® grafts. Fourteen patients with complex tissue defects were treated, including bone exposure in two cases, tendon exposure in seven cases and soft tissue defects in five cases. Nine cases had combined wound infections. The time interval between the first artificial dermis graft and the second split-thickness skin graft over it was 7·64 days on average. Dermal substitutes took place completely in all cases and there were no graft failures.
