説明

Pancreatic graft thrombosis is the primary cause of non-immunologic graft loss, with an incidence ranging from 5% to 15%. Therefore, developing a screening test to detect graft thrombosis after pancreatic transplantation is important. We created a screening test to assess graft thrombosis after pancreatic transplantation using contrast-enhanced ultrasonography (CEUS) with Sonazoid. A total of seven patients were examined using CEUS after undergoing pancreatic transplantation. All patients were observed to have a clear blood flow in the splenic vein in the pancreatic graft, while only one of the seven patients exhibited a blood flow in the horizontal portion of the splenic vein on Doppler ultrasonography performed immediately after pancreatic transplantation. CEUS with Sonazoid demonstrated the blood flow in the splenic vein and parenchyma of the pancreatic graft in detail, in spite of the slow and lateral blood flow in the splenic vein of the pancreatic graft immediately after transplantation.<br>Evaluation of tissue blood flow in pancreatic graft using ΔTp(V-P) calculated by time intensity curve as shown by CEUS correlates with endocrine function of pancreatic graft 1 month after transplantation. These findings suggest that CEUS should become one of the novel and useful examination for pancreas transplantation.
