Multirow CT in the follow-up of pancreas transplantation.
OBJECTIVE
Isolated pancreas or combined kidney-pancreas transplantation represents the only therapeutic weapon for complete resolution of type I diabetes mellitus. The purpose of the present study was to investigate the role of multirow CT in the follow-up of these patients.


METHODS
Thirty patients who underwent isolated (n = 13) or combined kidney-pancreas (n = 17) transplantation, using systemic-bladder (n = 7) or enteric-portal (n = 23) drainage, were evaluated with multirow CT (Light Speed Plus, GE Medical System). The CT study included unenhanced, arterial, and portal phases of the isolated pancreas, and a urographic phase for combined kidney-pancreas transplants. The acquisition was done with 1.25-mm collimation, 0.6-mm reconstruction interval, and a pitch of 6. A CT scan of the thorax was included if patients were suspected to have pulmonary complications.


RESULTS
In all cases it was possible to recognize the surgical technique performed for endocrine and exocrine pancreatic drainage, to evaluate the transplanted pancreas, and to identify possible complications. For example, CT identified thrombosis or stenosis of the arterial graft, partial thrombosis of the venous graft, ectasia of the common iliac artery and arterial graft, dehiscence of the duodenal-bladder anastomosis, infected abdominal collections, thrombosis of the internal iliac vein, and pulmonary infections.


CONCLUSIONS
Because multirow CT detects complications it is useful to follow isolated pancreas or combined kidney-pancreas transplants.
