Transplantation in mass of the kidneys.

Carrel revolutionized vascular surgery. He transplanted the kidney from one animal to another, an operation later carried out successfully in man. For his earlier work on vascular anastomosis and transplantation of viscera, see No. 2909.

In 1912 Carrel was awarded the Nobel Prize in Physiology or Medicine "in recognition of his work on vascular suture and the transplantation of blood vessels and organs." See also Nos. 3028, 11563, 3026, and 3027.
