Final answer:
An infected graft can lead to complications and risks, including spread of infection and failure to heal properly. The removal of the infected graft is necessary to prevent further infection and promote healing.
Step-by-step explanation:
When a graft becomes infected, it can lead to potential complications and risks. The infection can spread and cause systemic infection, resulting in sepsis. In addition, the infected graft may fail to heal properly, leading to chronic wounds or non-healing ulcers. The removal of the infected graft is considered a necessary intervention to prevent further spread of infection and promote healing. By removing the infected tissue, the source of infection is eliminated, reducing the risk of complications and allowing for the application of appropriate treatments.
