Sickling leads to vascular occlusion, end-organ ischemia, and decreased RBC lifespan, which, in turn, leads to pain crisis, acute anemia, sequestration, infection, and acute chest syndrome (ACS). ACS is lung injury due to vaso-occlusion in the pulmonary vasculature; many with ACS will have a concomitant vaso-occlusive pain crisis.
