How is factor X deficiency treated?

Factor X deficiency requires replenishing the missing coagulation factor quickly to restore the final common pathway of clot formation. Vitamin K helps only if the deficiency is due to lack of gamma-carboxylation (as with vitamin K deficiency or warfarin effect), not when the actual factor X protein is deficient. Fresh frozen plasma can supply factor X but needs large volumes and slower correction, increasing the risk of volume overload. Platelets do not replace coagulation factors. Prothrombin complex concentrate provides concentrated vitamin K–dependent factors II, VII, IX, and X, allowing rapid and effective replacement of factor X with much smaller volumes and quicker hemostatic correction.
