title: A new classification of hepatic territories using intraoperative ultrasound.
abstract: Intraoperative ultrasonography is now established as the most accurate technique for detecting and localizing hepatic tumors, be they primary or metastatic. A major problem is the accurate placement of any lesions found by intraoperative ultrasound and, hence, the correlation of the lesions found by ultrasound to the current classification of hepatic segments and to lesions seen by other imaging techniques. This paper outlines an objective and reproducible method of mapping hepatic lesions into territories defined solely by the major hepatic veins and their tributaries. It is a simple technique that can be readily used by any surgeon, which accurately determines the presence, number, size, and site of hepatic metastases.
