Localized hepatic ischemia after liver resection: a prospective evaluation.

Objective: To prospectively assess the frequency, severity, and extension of localized ischemia in the remaining liver parenchyma after hepatectomy.

Background: Major blood loss and postoperative ischemia of the remnant liver are known factors contributing to morbidity after liver surgery. The segmental anatomy of the liver and the techniques of selective hilar or suprahilar clamping of the Glissonian sheaths permit identification of ischemia on the surface of the corresponding segments for precise section of the parenchyma.
