Sickle Cell Anemia

Synonyms:
Hb SC disease,Hb-S/Hb-C disease,Hb-SS disease without crisis,Hemoglobin S disease without crisis,Sickle-cell/Hb-C disease without crisis,drepanocytosis,hemoglobin SC disease
Definition:
Sickle cell anemias are chronic hemolytic diseases that may induce three types of acute accidents: severe anemia, severe bacterial infections, and ischemic vasoocclusive accidents (VOA) caused by sickle-shaped red blood cells obstructing small blood vessels and capillaries. Many diverse complications can occur.
