CVST - Pathophysiology •Multiple etiologic factors •Usually one or more predisposing risk factors plus one inciting factor •Thrombosis develops through common pathways of: •Hypercoagulability •Hemoconcentration •Direct injury or inflammation of the vessel •Venous stasis •Transient and/or permanent risk factors raise suspicion for deposition. 1 It is a common venous thromboembolic (VTE) disorder with an incidence of nearly 1.6 per 1000 inhabitants a year.

Most PE commonly originate from a thrombus that has formed in the iliofemoral vein, deep within the vasculature of the lower extremity. It is commonly caused by a venous thrombus that has dislodged from its site of formation and embolized to the arterial blood supply of one of the lungs. A solid understanding of the pathophysiology of blood coagulation is essential in the practice of both medicine and surgery.

Due to the fact that mature thrombus composed of platelets, leukocytes and fibrin develops, and an active thrombotic and inflammatory process occurs at the inner surface of the vein, with an active inflammatory response occuring in the wall of the vein [20]. Venodilation may disrupt the endothelial cell barrier and expose the sub-endothelium, triggering coagulation. Autopsy findings of microthrombi in multiple organ systems, including the lungs, heart, and kidneys, suggest that thrombosis may contribute to multisystem organ dysfunction in severe COVID-19.

Irreversible formation of the blood clot is called thrombosis. Deep venous thrombosis usually arises in the lower extremities. Post-thrombotic syndrome is usually referred to as a syndrome because the signs and symptoms usually vary from patient to patient.

The pathophysiology of malignancy-related thrombosis is poorly understood, but tissue factor, tumor-associated cysteine proteinase, circulating mucin molecules, and tumor hypoxemia have all been implicated as causative factors. It is associated with significant morbidity and mortality if unrecognized.
