Imaging of pancreatic transplant vessels and anastomoses with 16-row multidetector computed tomography.
The aim of this study was to evaluate the usefulness of 16-row multidetector computed tomography (16-MDCT) in the assessment of the potency of arterial and venous vessels in combined kidney-pancreas transplant and detection of transplant-related complications. Fifteen patients underwent a combined kidney-pancreatic transplantation. On the seventh day after the operation, we performed 16-MDCT in arterial and portal venous phase to evaluate vessels, anastomotic sites, and pancreatic parenchymal vascularization as well as peripancreatic fluid collections. We visualized the pancreatic vessels and anastomosis sites in all cases. In 12 recipients, there were no abnormal findings as regards the patency of the arterial and venous vessels and the vascularization of the pancreatic parenchyma. In two patients, complete arterial thrombosis of the body and tail pancreatic graft vessels was recognized at 2 weeks after transplantation, resulting in graft removal. Thrombi were localized in the distal part of anastomoses. None of the patients had venous thrombosis. One recipient had stenosis of the venous anastomosis. Peripancreatic fluid collections were observed in seven patients. In conclusion, 16-MDCT is an efficient method to estimate pancreatic transplant vessels, localize thrombi, and detect other transplant-related complications.
