control.
Sickle Cell Disease – clinical
presentations
Vasoocclusive Crisis: Small vessel
occlusion secondary to noncompliant
RBC’s leads to distal hypoxia and pain.
 Examples include: dactylitis, bony pain
crisis, acute chest crisis, stroke, and
avascular necrosis of the femoral head.
 Treatment: Aggressive hydration and pain
control.

Sickle Cell Disease – clinical
presentations
Hemolytic Crisis: Massive destruction of
sickled cells leading to severe anemia and
shock. Look for jaundice.
 Aplastic Crisis: Shutdown of RBC
production (Parvovirus B-19).
 Sequestration Crisis: Splenic enlargement
can lead to a functional severe anemia.
Priapism.
