[Pancreas grafts. Nuclear medical perfusion to exclude vascular complications and rejection crises (author's transl)]

Perfusion studies with 99m Tc-DTPA, which has hitherto been used routinely to investigate renal grafts, have also proved useful for monitoring the perfusion of pancreas grafts. A total perfusion failure is equally reliably demonstrable as in renal grafts. Quantitatively smaller perfusion alterations can be demonstrated by monitoring the course. It seems possible to differentiate the salivary edema of a rejection reaction, well known from animal experiments, with the help of other parameters (e. g. creatinine). Further clinical studies are however necessary to confirm these results.
