A split thickness skin graft consists of the epidermis and a portion of the dermis, but it does not retain the vascular supply from the donor site when transplanted. This type of graft relies on the recipient site's vascularity to establish its own blood supply over time after transplantation. The initial healing process involves revascularization, where new blood vessels grow from the surrounding tissues of the recipient site into the graft.

Understanding this aspect is crucial because a lack of adequate vascular supply can lead to graft failure or necrosis. In contrast, full thickness skin grafts typically retain their vascular supply, allowing them to survive more readily in their new location. Therefore, it is essential for those involved in hyperbaric therapy and wound management to comprehend how different types of skin grafts function, particularly in their dependence on the recipient site’s vascular supply for nourishment after transplantation.
