CLAUDE COUINAUD is a French surgeon and anatomist who made significant contributions in the field of hepatobiliary surgery. He performed detailed anatomic studies of the liver and was the first to describe its segmental anatomy. He developed the concept of plates and vasculobiliary sheaths of the liver, and performed the first "controlled" hepatectomy by isolating and dividing the Glissonian sheaths going into the liver, prior to parenchymal dissection. He also performed the first biliary bypass to the left hepatic duct and the first "segment III bypass." His book Le Foie: Etudes Anatomique et Chirurgicales stands as the seminal work on hepatobiliary surgery and anatomy of the 20th century.
