What role does stasis play in thrombus formation?
Understand the Problem
The question is asking about the role of stasis in the process of thrombus (blood clot) formation, specifically how it affects endothelial function, platelet aggregation, development of venous thrombi, and coagulation factor depletion.
Answer
Stasis promotes thrombus formation by enabling accumulation of procoagulants and causing blood stagnation.
Stasis plays a critical role in thrombus formation by allowing the accumulation of procoagulant proteases like thrombin, which can overcome local anticoagulant defenses and initiate thrombus formation. It causes stagnation of blood, leading to local hypoxia and promoting coagulation.

More Information
Venous stasis is a major contributing factor in the development of venous thrombosis. However, it's typically part of a triangle with other factors (Virchow's triad) like endothelial injury and hypercoagulability that together result in thrombus formation.
Tips
A common mistake is considering stasis the sole factor in thrombus formation, when it usually works in combination with other factors like endothelial damage and increased coagulability.
