Kateria,
Her ferritin is dangerously high. Splenectomy might lower her iron just by removing the spleen and all the iron in her spleen, but that is not the best solution for the iron load. If her spleen has caused too much blood consumption for a long period, then it may need to be removed. I think she should be taking desferal 24/7 through either IV or a picc line. This is very urgent She needs aggressive chelation.
She can take any antioxidant supplements like natural vitamin E, IP6, wheatgrass, green tea extract, L-carnitine and others.
