First pancreas transplantation in the Netherlands

At Academisch Ziekenhuis Leiden (now LUMC) doctors perform the first successful pancreas transplantation in the Netherlands.

First successful stem cell transplant

Another first: doctors from Leiden perform the first successful bone marrow transplant on a child in Europe.

The transplant is a great success. From that moment on, Van Rood is also involved in bone marrow transplants.

Jon van Rood sets up Eurotransplant

Dr Jon van Rood sets up Eurotransplant, a collaboration between European transplant centres. Because the larger the network, the greater the likelihood of a match between donor and recipient. Belgium is the first to participate. After this, another seven European countries join. At first, only kidneys are exchanged, later other organs are added to the list. Since its founding, over 187,000 patients have received an organ via Eurotransplant.

First successful kidney transplantation

Leiden has another first: the first successful kidney transplantation. A mother donated a kidney to her son. In that same year, the first liver transplant also took place in Leiden, unfortunately without success. Kidneys and livers were already being transplanted in other western countries at the time. Rejection of the donor organs was a major problem. Jon van Rood discovers that kidney transplants have a higher success rate if the tissue types of the donor and recipient match.
