Hemihepatectomy

from Wikipedia, the free encyclopedia

The hemihepatectomy ( Greek ήμἰ hemi semi ', ἧπαρ Hepar [genitive ἧπατος hepatos ], liver', ἐκτομή ektomế , excision ') is the "anatomically correct" surgical removal ( resection ) of the right or left functional liver half; generally with blunt separation (squeezing; "finger dissection") within the boundaries of the corresponding liver segments , possibly - after the large vessels of the hepatic portal have been ligated beforehand  - from the hilus (hilar hemihepatectomy).
