IV	Segment IV Subdivided into IVa and IVb; situated between the falciform ligament and Cantlie's line (the plane of the middle hepatic vein running from the gallbladder fossa to the left side of the inferior vena cava). With segments II and III it constitutes the functional left liver.	—	—	okfonte PMC12916557, 'Couinaud classification' paragraph: 'Segment IV (a and b) is situated between the falciform ligament and Cantlie's line.
