Abstract:
Congenital Factor VII (FVII) deficiency is a rare autosomal recessive disorder with a prevalence of approximately 1:500,000. It plays a crucial role in initiating coagulation by activating Factors IX and X. Diagnosis typically involves prolonged prothrombin time (PT) and varies widely in clinical presentation. Management includes fresh frozen plasma (FFP), prothrombin complex concentrates (PCC), and recombinant activated FVII (rFVIIa), with rFVIIa often preferred due to its safety and efficacy. We present two pediatric cases: a five-year-old boy with a prolonged PT at 55% and FVII levels at 25.1%, and a two-year-old boy with a PT at 24% and FVII levels at 4.6%. Both cases highlight the importance of thorough hemostatic evaluation and tailored management strategies in FVII deficiency.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
