A beneficial effect of splenectomy in sickle cell anemia and chronic renal failure
A 25-year-old black male with known sickle cell disease developed progressive chronic renal failure. Eight months after the initiation of chronic hemodialysis, he developed a rapidly-increasing transfusion requirement. The requirement was one unit of blood per week in order to maintain a hematocrit of 16%. His spleen was found, at that time, to be enlarged both on physical examination and radioisotopic scan. A radiochromium study disclosed a red blood cell half-life of 17 days. No evidence of splenic sequestration could be demonstrated isotopically. Splenectomy produced a marked decrease in the patient's transfusion need. Presently, this patient needs one unit of blood every 10 to 12 weeks to maintain a hematocrit of 18%.
