entrapment of erythrocytes/leukocytes in microcirulation->tissue hypoxia, inflammation, necrosis d/t inadequate blood flow->perfusion resumes, substances are released causing oxidative damage to vessel->damage to the epithelium and vasculopathy develops | acute vaso-occlussive crisis |
from infection with the human parvovirus, hemoglobin drops rapidly and the marrow cannot compensate, leading to an absence of reticulocytes | aplastic crisis |
results when organs pool the sickled cells; spleen is often effected in children (splenic infarction happens often by 10 years of age, leaving spleen non-functional); liver and lungs are effected in the adult population | sequestration crisis |
