Background
- Leading cause of pediatric mortality related to sickle cell disease[1]
- More common in pediatric patients as many adults with SCD have autoinfarcted their spleen
- Earliest life threatening complication of SCD with median age 1-43
- Red blood cells sickle, aggregate, and occlude splenic vasculature[2][3]
- Sequestering leads to splenomegaly
- Defined as splenomegaly and a 2g/dL drop in hemoglobin
- Some resources differentiate between major and minor episodes depending on the hgb drop
- Defined as splenomegaly and a 2g/dL drop in hemoglobin
- Lifelong prevalence 7-30%3
- Often precipitated by underlying infection (pneumonia, gastroenteritis)
Clinical Features
- Abdominal pain
- Fatigue
- Pallor
- Tachycardia
- Anemia
- Hypotension
- Circulatory collapse
- Splenomegaly
Differential Diagnosis
