Is Duplex-Ultrasound a useful tool in de ning rejection episodes in composite tissue allograft transplants? Open
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 al…
