Segmentatio hepatis: lobi, partes, divisiones et segmenta These are the developmental, functional and surgically separable units of the liver and are based on the distribution of the v. portae hepatis, aa. hepaticae and ductus hepatici. The segments are numbered according to Couinaud (1957): the segmentum posterius, which corresponds to the lobus caudatus, is numbered as I and the remainder II-VIII clockwise from the left beginning with the segmentum posterius laterale sinistrum. The divisio lateralis sinistra (II & III) is separated from the divisio medialis sinistra (IV) and the pars posterior hepatis (1) by the fissura umbilicalis. The pars hepatis sinistra and the pars hepatis dextra are separated by an oblique plane, fissura portalis principalis, that runs anteriorly from a line between the long axis of the fossa vesicae biliaris and the middle of the vena cava inferior as it lies in contact with the liver posteriorly and transects the lobus quadratus. The divisio medialis dextra (V & VIII) is separated from the divisio lateralis dextra (VI & VII) by the fissura portalis dextra. Couinaud C. 1957. Le foie - Etudes Anatomiques et Chirurgicales.
