When vascular damage or a state of circulatory stasis occurs, patients develop thromboembolic complications.8 The clotting of blood is the sequential initiation, interaction, and completion of several stages of hemostasis. The vascular stage, initiated by tissue injury, is followed by the platelet phase resulting in platelet plug formation. In the plasma phase, a fibrin clot is generated via interactions involving numerous clotting factors. To prevent thromboembolic complications, patients are prescribed antithrombotic agents and/or an oral anticoagulant. Key recommendations for practice are presented in Table 15.
