摘要Background: Indocyanine green (ICG) fluorescence imaging is a promising tool for intraoperative decision-making during surgical procedures, in particular to assess organs perfusion. Methods: We used the ICG fluorescence during liver transplantations in six cirrhotic patients to help assessing the graft biliary duct perfusion in order to identify the appropriate level to perform the anastomosis. We also used ICG fluorescence also in five patients receiving kidney-pancreas transplantation to evaluate the perfusion levels of the duodenal stump of the pancreas graft. Results: Follow-up period for the patients was 12 months. The perioperative period was uneventful, no biliary complications such as leaks or stenosis were reported after liver transplantation, no complications of the entero-enteric anastomoses occurred after pancreatic transplantation. Conclusions: ICG fluorescence seems to safely provide important objectifiable perfusion information during organ transplantation procedures that can integrate surgeon's expertise. In fact, detecting intra-operatively perfusion defects, it allows real time modifications on technical strategies potentially useful to reduce the feared risk of anastomotic leakage and consequent severe complications.
