Splenic sequestration crisis is a life-threatening illness common in pediatric patients with homozygous sickle cell disease and beta thalassemia.Up to 30% of these children may develop splenic sequestration crisis with a mortality rate of up to 15%.
Increased deoxygenation causes sickling of red blood cells, which adhere to the spleen wall and splenic macrophages causing ischemia. [2] This ischemia can result in splenic sequestration, where large amounts of blood pool in the spleen but do not flow within vasculature. [11]
A splenic sequestration crisis, also known as a spleen crisis, is a medical emergency that occurs when sickled red blood cells block the spleen's filter mechanism, causing the spleen to swell and fill with blood. The accumulation of red blood cells in the spleen results in a sudden drop in circulating hemoglobin and potentially life-threatening ...
