Left posterior sector of liver consists of
Lobar anatomy of the liver Liver is divided into two lobes by the main poal fissure (Scissura), known as Cantlie's line Cantlie's line describes a 75deg angle with a horizontal plane It extends from the gallbladder fossa to the left side of the IVC Right and left halves of the liver is delineated by a plane through the MHV and IVC Right poal fissure divides the right lobe into an anteromedial and posterolateral sector. RHV courses along this fissure Right poal fissure describes an angle of 40deg with the transverse plane. Left poal fissure divides the left lobe into an anterior and posterior sector, LHV courses along this fissure In the right lobe Anteromedial sector : Segment V anteriorly and segment VIII posteriorly Posterolateral sector : Segment VI anteriorly and segment VII posteriorly In the left lobe Anterior sector is divided by the umbilical fissure into segment IV and segment III Posterior sector is comprised of only one segment, segment II Umbilical fissure is not a Scissura, does not contain a hepatic vein, but contains the left poal triad. Left Scissura runs posterior to the ligament I'm teres and contains the LHV; the left liver is split into an anterior (segments III and IV) and posterior (segment II- the only sector composed of a single segment) sector by the left Scissura.
