Following blunt trauma to the spleen, what causes disseminated intravascular coagulation (DIC) due to widespread platelet aggregation?

💡 Explanation

DIC following splenic trauma arises because the damaged spleen releases tissue factor into the circulation, which initiates the coagulation cascade, leading to excessive platelet aggregation and fibrin formation. Therefore, option C is correct; rather than antithrombin III increase which inhibits coagulation.
