The following statement(s) is/are true concerning the widely accepted French or Couinaud’s nomenclature for liver anatomy

a. The liver is divided into eight discrete segments based on portal pedicle branches and hepatic venous drainage

b. This anatomy is particularly useful in allowing less than lobar segmental anatomical resections that minimize blood loss and loss of hepatic reserve

d. Segments II and III are synonymous with the left lateral segment based on English nomenclature 

In the now widely accepted French (Couinaud’s) nomenclature, the liver can be divided into eight discrete segments based on portal pedicle branches and hepatic venous drainage. Enumeration of the segments begins left to right, beginning with segment I, the caudate lobe. The left lateral sector consists of a superior segment II and an inferior segment III and is synonymous with the left lateral segment in older terminology. The major advantage to this detailed segmental anatomy, which is based on discrete portal pedicle branches, is to accurately locate individual lesions in the hepatic substance by preoperative imaging and intraoperative ultrasound and to allow the possibility of less than lobar segmental anatomical resections that minimize blood loss and functional loss of hepatic reserve.
