Erythraemia in renal transplantation.

Seven cases of erythraemia following successful renal transplantation are described. This complication was not necessarily associated with clinical evidence of rejection of the transplant, and the prognosis so far as rejection was concerned was excellent. Four patients, however, developed thromboembolic pulmonary complications, and two other patients had thrombotic episodes. Hence it is suggested that treatment either by anticoagulation or by venesection is indicated.
