Congenital factor VII deficiency is a bleeding disorder in which there are low levels of factor VII in the blood. Factor VII plays an important role in the blood-clotting process. When there is not enough factor VII in the blood, clotting can take much longer than normal or may not occur at all.
- Mild to moderate congenital factor VII deficiency is marked by increased bleeding after surgery and trauma
- Severe congenital factor VII deficiency is marked by spontaneous, severe, and even life-threatening bleeding
