To preserve as much normal liver tissue as possible in patients having
segmental and major anatomical liver resections for primary and metastatic
cancer, one of us (Q.-J.O.) performed segmental hepatic vein ligation with
preservation of the involved liver segments in eight patients undergoing
hepatic resections. No early complications were found related to necrosis
of the involved segments. Needle biopsy of the segments in five patients
revealed normal survival of the hepatic tissue. The results in these
patients indicate that hepatic vein ligation is a safe procedure that
permits preservation of segments of the liver in patients having hepatic
resection and can be used as an alternative to routine hepatic lobectomy
for the treatment of liver tumors in selected patients.
