Hepatic Venous Oxygen Saturation Monitoring Indicated Accidental Resection of Proper Hepatic Artery in a Patient Undergoing Pancreatectomy

Abstract

We report a useful case of hepatic venous oxygen saturation (ShvO₂) monitoring, during hepatic blood flow blocking and restoration. The patient was scheduled for a pancreatectomy from a diagnosis of pancreatic body tumor in a 68-year-old man.
The proper hepatic artery that maintains the hepatic blood flow was resected accidentally, because the tumor invaded the organs and blood vessels around the liver. ShvO₂ decreased immediately because of interruption of the hepatic blood flow. The hepatic artery reconstruction was performed in order to maintain the hepatic blood flow. Thereafter, ShvO₂ was recovered. It has been suggested that monitoring of ShvO₂ is a useful index of hepatic blood flow.
