The role of early baseline computed tomography in the interpretation of morphological changes after kidney-pancreas transplantation.
In a prospective study, 17 early baseline computed tomography (CT) scans were obtained 2 or 3 days after simultaneous kidney-pancreas transplantation. Morphological changes and their relevance to the early detection of graft rejection and complications were evaluated. The pancreatic grafts were enlarged and showed signs of mild pancreatitis. Serial scans obtained during the first renal graft rejection episode were compared with the baseline CT scans (n = 7). They showed a significant increase in pancreatic graft size in the case of biopsy-proven severe renal graft rejection (P = 0.008). Normally functioning pancreatic allografts showed a 15%-40% decrease in size 1-6 months after transplantation. We conclude that the morphological changes observed early after transplantation are compatible with mild pancreatitis, which may contribute to the development of pancreatic graft thrombosis. There is an increase in the number of morphological changes during severe rejection, yet enlarged pancreatic grafts appear to recover from transplantation-related damage and regain their normal size without signs of atrophy.
