The modern vision of the vascular anatomy of the liver by Leonardo da Vinci

Abstract

Leonardo da Vinci's analysis and artistic representation of the hepatic vascular anatomy, performed more than 500 years ago, has not yet been fully recognized nor appreciated. Leonardo modified the anatomic concepts of Galen, up until then in vogue, and described for the first time the intrahepatic distribution of the proper hepatic artery, the portal vein, and the hepatic veins. The depiction of these structures is surprising for its clarity and perspective and reproduces the anatomic situation almost exactly. The segmentary division of the liver which several centuries later became the basis of modern resection hepatic surgery was extremely clear in Leonardo's mind.
