Acute Splenic Sequestration Crisis in Hemoglobin SC Disease: Efficiency of Red Cell Exchange.

Acute splenic sequestration crisis (ASSC) is recognized as a serious complication of sickle cell disease in children. ASSC presents with progressive splenic enlargement, transfusion-dependent anemia, and, eventually, circulatory compromise. ASSC is rare in adult patients, thus making its management and outcome in adults not well-defined. The purpose of this article is to describe our experience in managing ASSC in an adult female with hemoglobin (Hb) SC disease. The patient underwent an automated red blood cell (RBC) exchange, thus avoiding a planned splenectomy. To the best of our knowledge, our case is the third report in the literature on the use of RBC exchange in adults with HbSC disease and ASSC. RBC exchange should be considered in adults with HbSC disease with ASSC not responding to simple transfusion; a treatment that could alleviate patients' symptoms and avoid splenectomy complications, especially in young patients.
