Plasmatic coagulation has like purpose the formation of a stable clot of fibrina, this process is possible thanks to the intervention of the factors of the coagulation that are plasmatic proteins. Some of these factors are vitamin K dependent (factors II, VII, IX and X) and all except for the factors VIII, XII and XIII which are synthesized in the liver. Three clinical cases of patients are described who present serious hemorrhagic disorders, associated to different hepatic alterations, which do not respond to conventional treatments. As a measure of urgency and therapeutic alternative, the administration of recombinant factor VII is used with the aim of activating the extrinsic pathway of the coagulation and of obtaining a positive answer in the control of the hemorrhage.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
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 forms a...
