What is factor 7 in surgery?

Surgical Care Prophylactic administration of factor VII concentrates or plasma may help minimize bleeding during surgery. For surgery, factor VII concentrates have been used in doses ranging from 8-40 U/kg every 4-6 hours.

Is factor 7 deficiency serious?

Bleeding in severe factor VII deficiency can result in life-threatening complications. These include major gastrointestinal bleeds as well as head bleeds (intracranial hemorrhage), often during the first few weeks or months of life. Although quite rare, head bleeds have been reported in adults as well.

Can factor 7 deficiency be cured?

‌Factor VII deficiency can be treated using these clotting agents, which promote blood clotting and prevent bleeding: Recombinant factor VIIa. This is a replacement therapy to help increase the levels of factor VII in your body.

How is factor VII treated?

The main treatment for FVII deficiency is recombinant factor VIIa (rFVIIa). Prothrombin complex concentrates (PCCs) can also be used, but the amount of factor VII they contain can vary considerably. Fresh frozen plasma (FFP) is another option. In some patients, the use of FFP has led to blood clots.

Is Factor 7 hereditary?

Factor VII deficiency may be inherited or acquired. The inherited from is caused by mutations in the F7 gene and inheritance is autosomal recessive . The acquired form is not inherited and may be caused by liver disease, blood cell disorders, certain drugs, or vitamin K deficiency.

What causes low factor VII?

It can be caused by liver disease or by blood cell disorders such as myeloma or aplastic anemia . Acquired factor VII deficiency can also be caused by certain drugs such as medicines that prevent clotting, or by a deficiency of vitamin K.

What activates factor VII?

Factor VII is feedback activated by many of the proteases produced during the blood coagulation response, but the extent of the thrombin production reaction is largely dependent on the preexistent concentration of factor VIIa in plasma and the concentration of tissue factor presented by the vascular lesion.

Does factor VII increase in pregnancy?

Literature indicates that whilst Factor VII levels rise during pregnancy in normal women, no increase is seen in homozygous cases, whereas there is a moderate rise in heterozygous individuals.
