Effect of Splenectomy on Anemia in Patients on Regular Dialysis Treatment

Splenectomy was performed in 7 patients on regular hemodialysis treatment who had disabling anemia. All patients had a short 51Cr red cell survival time and an increased splenic uptake of red cells verified by external counting and computer-aided scintigraphy. The need for blood-transfusions was eliminated in all except one. In all patients the hemoglobin concentration rose after splenectomy. This was probably an effect of a reduced plasma volume and the removal of a large pool of non-circulating red cells. No consistent changes in the red blood cell survival time or the red cell volume were observed. The white cell and the platelet counts in the blood rose to twice the preoperative value. No adverse effect of the splenectomy was observed.
