Splenic sequestration occurs in people with
sickle cell disease when large numbers of sickled red
blood cells become trapped in the
spleen, causing it to suddenly enlarge. This condition
most commonly occurs in children age 6 months to 2 years and often follows or
accompanies a simple respiratory infection.1 Without
emergency medical care, splenic sequestration can cause death in a matter of
hours.
Splenic sequestration causes sudden and severe
anemia, with symptoms of sudden weakness, pale lips,
rapid breathing, excessive thirst, abdominal pain, and rapid heartbeat.
Parents of babies and young children with sickle cell disease are
advised to monitor their children for spleen enlargement, as demonstrated by a
health professional. A suddenly enlarged spleen requires emergency medical
care.
