Factor eight inhibitor bypassing activity (FEIBA), Anti-Inhibitor Coagulation Complex has been used for over 30 years in hemophiliac patients with inhibitors. The history of its use is reviewed here, including issues related to thrombosis, efficacy, and comparison to alternative bypassing agents. The need for surrogate assays to monitor effective hemostasis with the use of FEIBA remains.

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...

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...
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...
