Partial splenic embolization for Felty's syndrome: a 10-year followup.

Partial splenic embolization was performed in a case of Felty's syndrome in 1980. The granulocyte count has since remained normal without serious infections for the 10 years after the procedure. This is the first report of partial splenic embolization in this syndrome. This treatment may have an advantage over splenectomy because the defense mechanisms of the spleen are preserved and overwhelming infections may occur less frequently.
