Rescue splenic artery embolization in an adult patient of sickle cell disease presented with acute splenic sequestration crisis.

Background: Splenic sequestration crisis is a potentially fatal complication of sickle cell disease, mainly seen in young children. Only a few case series describe the acute splenic sequestration crisis in adults and its management, which primarily consists of supportive care and, in some cases, splenectomy. Splenic artery embolization has seldom been described in sickle cell disease. This is probably the first case in which an adult with sickle cell disease presented with an acute splenic sequestration crisis was managed successfully through splenic artery embolization.

Results: This 22-year-old female, a known case of sickle cell disease, presented with severe pain in the abdomen and low-grade intermittent fever for two days, secondary to an acute splenic sequestration crisis. The diagnosis of acute splenic sequestration was made based on clinical and blood parameters, ultrasonography, and computed tomography. Even with adequate supportive care and blood transfusions, the patient's condition worsened with a rapid fall in the hemoglobin and total platelet count. Considering splenectomy to be a high-risk procedure for this patient, a decision of rescue splenic artery embolization was taken, which was successful.

Conclusion: Splenic artery embolization may be considered a lifesaving procedure in patients with acute splenic sequestration, where the risk of splenectomy can be high. Adequate post-procedure supportive care is vital for preventing complications.
