Summary
Excessive blood loss during hemispherectomy surgery significantly impacts children's blood clotting. Newer surgical methods may reduce these risks, even in young patients undergoing epilepsy surgery.
Area of Science:
- Pediatric Neurosurgery
- Hematology
- Pediatric Intensive Care
Background:
- Excessive perioperative hemorrhage and hemodynamic instability are known risks of hemispherectomy.
- Understanding the impact on hematological and coagulative patterns is crucial, especially in pediatric patients.
Purpose of the Study:
- To analyze the effects of hemispherectomy on hematological and coagulative parameters in children.
- To investigate these effects specifically in younger patients undergoing the procedure.
Main Methods:
- Retrospective analysis of 18 children undergoing hemispherectomy (anatomical or functional) between 1993-2003.
- Comparison with a historical cohort of 13 children operated on before 1992.
- Focus on patients with hemimegalencephaly (HME) and other epileptogenic lesions.
Main Results:
- Significant influence of blood loss and transfusions on hematologic/coagulative status observed.
- A strong correlation found between estimated red cell volume (ERCV) loss and hemostatic impairment.
- Analysis highlights the hematological changes post-hemispherectomy.
Conclusions:
- Blood loss and transfusions profoundly affect children's hematologic and coagulative status after hemispherectomy.
- Estimated red cell volume loss is strictly correlated with hemostatic impairment.
- Modern surgical techniques show promise in reducing blood loss and associated risks, even in younger pediatric patients.
