Sentinel Skin Allograft for Monitoring of Composite Tissue Transplants Rejection
In contrast to visceral solid-organ transplants, a vascularized composite tissue allograft (CTA) is not a single tissue, and is histologically heterogeneous. It is a neurovascularized module of nonvital tissues which include structural, functional and aesthetic units. CTAs are composed of a large spectrum of ectodermal tissues: epidermis and epidermal derivatives such as nails and hair, nerves ...
متن کاملComposite tissue allograft transplantation of cephalocervical skin flap and two ears.
Malignant melanoma is one of the most aggressive tumors, with an incidence that continues to increase.1 It is liable to proliferate and metastasize with chemoresistance in a majority of cases. Surgical resection remains the primary treatment for cutaneous malignant melanoma both primary and recurrent if possible. Monochemotherapy with dacarbazine is still the first choice for metastases,2 becau...
متن کاملEx Situ Limb Perfusion System to Extend Vascularized Composite Tissue Allograft Survival in Swine.
BACKGROUND Organ perfusion systems have successfully been applied in solid organ transplantations. Their use in limb transplantation and replantation has not been widely investigated. In this study, we tested the potential for ex situ perfusion system to prolong limb allograft viability in a swine forelimb amputation/replantation model. METHODS Fourteen swine were used. In group 1 (n = 4), we...
متن کاملIs Duplex-Ultrasound a useful tool in defining rejection episodes in composite tissue allograft transplants?
Immunologic reactions in transplanted organs are in more or less all allograft patients detectable: clear parameters exist as e.g. in renal transplants where the clearance power reduces by rejection. On the contrary, in composite tissue allografts clear and objective indicators stating a rejection episode lack. We present the case of a hand-transplanted subject with signs of acute transplant re...
متن کاملThe Banff 2007 working classification of skin-containing composite tissue allograft pathology.
Composite tissue allotransplantation (CTA) is a recently introduced option for limb replacement and reconstruction of tissue defects. As with other allografts, CTA can undergo immune-mediated rejection; therefore standardized criteria are required for characterizing and reporting severity and types of rejection. This article documents the conclusions of a symposium on CTA rejection held at the ...
