What can cause rejection of a tissue graft in the body?
A tissue graft can be rejected by the body if the immune system recognizes it as foreign and attacks it. This immune response can be triggered by differences in genetic markers between the donor and recipient, leading to rejection. Inadequate matching of the donor tissue with the recipient can also contribute to rejection reactions.
What instrument is used to take split-thickness graft?

Why are holes made on donor skin graft?
Holes are made in donor skin grafts to promote better integration and healing when the graft is placed on the recipient site. These perforations allow for fluid drainage and enhance vascularization, which is crucial for the graft to receive nutrients and oxygen from the underlying tissue. Additionally, the holes can help reduce the risk of hematoma formation and improve the overall success of the graft.
What is Graft versus host disease?
What does the term "Graft versus host disease" mean? Immunologic reaction involving the attack of host cells by donor immune cells.

What is the most common reason for graft failure?
The most common reason for graft failure is the formation of a hematoma, or collection of blood in the injured tissues.
What is the code for Costochondral cartilage graft?

What is the CPT code for a sheath split-thickness skin graft?
