The dorsal sector of human liver: embryological, anatomical and clinical relevance.

摘要: The dorsal liver sector has been recognized as the parenchyma surrounding vena cava and is quite independent of remaining liver. It that part organ in which hepatic portion develops its venous outflow remains strictly connected with by means multiple, not dissectable effluents well main veins. Therefore, this a major shunt between veins inferior cava, enlarges ensures drainage for survival cases Budd-Chiari syndrome. consists two segments: left one (segment I) corresponding roughly to caudate lobe right IX) front on including so-called process. identification detailed anatomy primary importance surgical practice, since cholangiocarcinoma bile duct hilar confluence extends makes resection necessary efficient therapy due consideration pedicles segment I IX required perform successful hemihepatectomy partition split grafting.
