Insights
Severe factor V deficiency presents varied bleeding risks, even with very low factor levels. This study details surgical management in three children with severe factor V deficiency, highlighting experiences with fresh frozen plasma.
Area of Science:
- Hematology
- Pediatric Surgery
- Coagulation Disorders
Background:
- Severe homozygous factor V (FV) deficiency is rare, affecting approximately one in a million individuals.
- Patients with FV levels below 0.01 IU mL(-1) exhibit a spectrum of bleeding phenotypes, from mild to severe neonatal intracerebral hemorrhage.
- Current treatment options for FV deficiency are limited to fresh frozen plasma (FFP) or solvent detergent FFP.
Observation:
- This study reports on the surgical hemostatic management of three pediatric patients with severe FV deficiency.
- A total of 13 surgical procedures were performed across these three children.
- The experience focuses on the use of FFP for hemostatic cover during surgery.
Findings:
- The study provides practical insights into managing surgical bleeding in severe FV deficiency.
- It underscores the challenges associated with inadequate hemostasis in this rare bleeding disorder.
- The data contributes to understanding the clinical application of FFP in complex surgical scenarios for FV deficient patients.
Implications:
- The findings may inform surgical strategies for patients with severe FV deficiency.
- Further research into optimized hemostatic agents for severe FV deficiency is warranted.
- Improved management protocols could reduce bleeding complications in pediatric patients undergoing surgery.
Abstract:
Homozygous severe factor V (FV) deficiency has a prevalence of around one per million. Even in patients with FV levels of <0.01 IU mL(-1) there appears to be a variation in bleeding phenotype in that there is a subgroup of affected individuals who present in later childhood and have a relatively mild bleeding phenotype, but there are children who present as neonates with intracerebral bleeding events and who have a much more severe bleeding phenotype. The only available current FV replacement is in the form of fresh frozen plasma (FFP) or solvent detergent FFP. We present here our experience with surgical haemostatic cover for 13 surgeries in three children with severe FV deficiency.
