Staged Single Ventricle Palliation and Homozygous Sickle Cell Disease

Area of Science:

• Cardiology
• Hematology
• Pediatric Medicine

Background:

• Sickle cell disease (SCD) patients are vulnerable to hypoxemia, which can precipitate sickling crises.
• Staged single ventricle palliation, including the Fontan pathway, involves periods of hypoxemia.
• Managing patients with both SCD and single ventricle physiology presents unique clinical challenges.

Observation:

• A child with homozygous sickle cell disease and single ventricle physiology underwent staged palliation.
• The patient tolerated prolonged hypoxemia during the initial stages of the Fontan pathway.

Findings:

• Successful completion of staged single ventricle palliation was achieved in this complex patient.
• This case demonstrates the feasibility of managing hypoxemia in a pediatric SCD patient undergoing Fontan palliation.

Implications:

• This case highlights a potential strategy for managing pediatric patients with combined SCD and single ventricle physiology.
• Further research may explore protocols to mitigate hypoxemia risks during Fontan pathway palliation in SCD patients.
• This successful outcome offers hope for similar complex pediatric cases.
