The world's first successful quadruple limb transplant operation was carried out at a Turkish hospital. Two arms and two legs of a deceased donor were transplanted to a patient. The operation lasted from Friday to Saturday at the medical centre of Hacettepe University in Ankara Xinhua quoted the semi-official Anatolia news agency as saying. It was a very complicated organ transplant operation because almost 50% of the patient's body had to be changed. Earlier in January a triple limb transplant at the Mediterranean University Hospital in Turkey failed as the doctors had to remove the leg due to tissue incompatibility.
