Background:
Pancreatectomies combined with arterial resection can be indicated for pancreatic cancer. In a pancreatectomy with arterial resection, intraoperative confirmation of blood flow through reconstructed vessels is crucial. This study highlights the usefulness of SPY laser fluorescence imaging during a pancreatoduodenectomy with common hepatic artery resection (PD-CHAR).
Patient And Methods:
A 55-year-old man with borderline resectable pancreatic head cancer underwent a PD-CHAR. After confirming tumor resectability, reconstruction of the CHA to the proper hepatic artery was performed. Subsequently, the superior mesenteric vein was reconstructed.
Results:
SPY laser fluorescence imaging demonstrated arterial blood perfusion to the liver through the reconstructed hepatic artery, followed by perfusion from the portal vein. The operation lasted 493 min, with an estimated blood loss of 400 mL. The postoperative course was uneventful with good arterial blood flow.
Conclusion:
The SPY Portable Handheld Imager could be valuable for visualizing blood flow in reconstructed vessels and assessing tissue perfusion during a pancreatectomy combined with vascular reconstruction.
