The four main types of tissue transplantation are xenotransplantation, allotransplantation, isotransplantation and autotransplantation, while the common tissues transplanted include skin, bone, corneal and vessel grafts. [3] Tissue transplantation comes with risks and complications, including immune rejection and viral infections.
The Banff Foundation for Allograft Pathology also known as the Banff Foundation for Transplant Pathology is a nonprofit Swiss foundation which aims to "lead development and dissemination of the international Banff Classification of Allograft Pathology and to facilitate multidisciplinary, collaborative research to enhance its scientific basis and clinical utility to improve the care of ...
The initiative was "inspired by the then recent development of a consensus grading system for diagnosis of rejection in cardiac allografts led by Dr Margaret Billingham, a key participant at the first Banff transplant pathology meeting". [1]
Acute rejection is a category of rejection that occurs on the timescale of weeks to months, with most episodes occurring within the first 3 months to 1 year after transplantation. [ 6 ] [ 8 ] Unlike hyperacute rejection, acute rejection is thought to arise from two distinct immunological mechanisms as lymphocytes , a subset of white blood cells ...
As with many operations, allotransplantation risks some side effects. A limiting factor in tissue allotransplantation for reconstructive surgery deals with the side effects of immunosuppression (metabolic disorders, malignancies, opportunistic infections) which is a predominant issue. The risk of transmitting infection is high.
Rejection mediated by T lymphocytes sensitized by direct allorecognition pathway is predominant in the short period after the transplantation, but usually subsides with depletion of passenger cells while indirect recognition contributes to continuing graft damage and plays role in chronic rejection.
The CCC System uses a five-character structure to code the two terminologies: (1) CCC of Nursing Diagnoses and Outcomes and (2) CCC of Nursing Interventions and Actions. The CCC coding structure is paced on the format of the International Statistical Classification of Diseases and Related Health Problems: Tenth Revision: Volume 1, WHO , 1992 .
Chronic rejection is not yet fully understood, but it is known that it is associated with alloantibody and cytokine production. Endothelium of the blood vessels is being damaged, therefore the graft is not sufficiently supplied with blood and is replaced with fibrous tissue ( fibrosis ). [ 4 ]
