Abstract:
The association between sepsis and thrombotic complications is still not well known. Different mechanisms have been shown to be involved in the sepsis-induced prothrombotic state, but clinical scenarios may differ. In this review, we have summarized the role that bacterial products such as porins and toxins can have in the induction of the prothrombotic state during sepsis and the interaction that they can have with each other. Furthermore, the above-mentioned mechanisms might be involved in the pattern of the clinical presentation of thrombotic events during bacterial sepsis, which would secondarily explain the association between sepsis and venous thromboembolism, the association between sepsis and disseminated intravascular coagulation, and the association between sepsis and microangiopathic venous thromboembolism.

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...
