In the "cascade" and "waterfall" theories of blood coagulation, factor XI was envisioned as playing a critical role in the initiation of coagulation through "contact" activation and the "intrinsic" pathway (1,2). The more recent realization that patients individually deficient in a "contact" factor (factor XII . prekall ikrein, o r high molecular weight kininogen [HMWK]) do not bleed (3) and the observation by Bsterud and Rapaport that the factor VIIaltissue factor catalytic complex activates not only factor X. but also factor IX (4), has suggested that tissue factor and the "extrinsic" pathway of coagulation are responsible for triggering hemostasis in vivo. The properties of the recently rediscovered coagulation regulator, tissue factor pathway inhibitor (TFPI) (5-7). which produces factor Xa-dependent feedback inhibition of factor VIIaItissue factor, have led to the formulation of a revised theory of coagulation that integrates components of both the classical extrinsic and intrinsic coagulation pathways into a single pathway (Fig. 1) (5.6). Coagulation is initiated when damage to blood vessels at the site of a wound allows exposure of blood to the tissue factor constitutively produced by cells beneath the endothelium. The factor VII or factor VIIa present in plasma then binds to this tissue factor, and the factor VIIaltissue factor complex activates some factor X to Xa and
