RESUMO
Vascular thrombosis is a cause of allograft loss after pancreas transplantation. We present the use of intraoperative fluorescence imaging with the SPY imaging device (Novadaq Technologies Inc, Toronto, Canada) in two pancreas transplants as a means to assess potency of the vascular anastomoses. Intravenous indocyanine green 2.5 mg/mL was fluoresced with the device to create the intraoperative video sequences, which were recorded. After 60-day follow-up, real-time SPY imaging on these two pancreas transplants did not demonstrate adverse effects on patients or the transplanted allografts. This method of vascular imaging could prove useful in improving short-term graft survival and possibly lowering the thrombosis rates seen with pancreas transplantation. Long-term correlation studies between intraoperative findings and graft survival must be performed to confirm the utility of this imaging method.
