Rhesus-Inkompatibilität
In 1963, after three unsuccessful attempts, Liley successfully carried out the first ever successful intrauterine blood transfusion. The fetus had Rh disease/hemolytic disease and had been expected to die before birth. The highly publicised procedure was a milestone in not only medical treatment but also public perception. Initially the procedure had a success rate of only about 40%, but this rose over time.
