From 1981-1982 we performed partial splenectomy in 6 children with beta-thalassaemia major as an alternative to splenectomy to reduce transfusion and to preserve some splenic immune function. In two of our young patients with transfusion requirements of 150 ml/kg/year, where more than 2/3 of the spleen was removed, the number of transfusions was significantly reduced with prolonged intervals, haemoglobin rose with a marked improvement in the general condition, nutrition and growth. There were no major post-operative complications. 2 years' follow-up revealed no infection without sepsis prophylaxis.
