[Erythropheresis in 4 cases of congenital hemolytic anemia].

Erythrocytapheresis was performed 6 times in 4 patients with sickle cell anemia and thalassemia. Good results were obtained, particularly in pregnant patients, no crisis being observed during pregnancy. In the other patients the painful crisis was suppressed over 4 months. The technic is very easy. The Haemonetics H 30 was used, 70% of red cell volume being removed and replaced with leukocyte-poor blood.
