Summary
Sickle C disease patients needing surgery can benefit from exchange transfusion. This procedure effectively lowered hemoglobin S levels, preventing intraoperative complications in a mitral valve replacement case.
Area of Science:
- Hematology
- Cardiovascular Surgery
- Transfusion Medicine
Background:
- Sickle C (SC) disease is a rare blood disorder presenting surgical challenges.
- Patients with SC disease and prior hemolytic crises often require intervention to prevent intraoperative sickling.
- Homologous transfusion is a common method to reduce circulating hemoglobin S (HbS).
Observation:
- A 25-year-old male with SC disease and a history of sickle cell crises required mitral valve replacement.
- The patient had a baseline HbS level of 53%.
Findings:
- Intraoperative exchange transfusion was employed during the mitral valve replacement surgery.
- The procedure successfully reduced the patient's HbS level from 53% to 7%.
Implications:
- Exchange transfusion is a viable strategy for managing SC disease patients during major surgery.
- This intervention can mitigate the risk of intraoperative sickle crisis in high-risk patients.
- Successful application in mitral valve replacement highlights its utility in complex cardiac procedures.
