Thrombus structure and composition are the main determinants of the severity, course, and outcomes of thrombosis. Detailed thrombus morphology has become available due to mechanical thrombectomy, which allows extraction of fresh thrombi from patients followed by scanning electron microscopy. The major structural elements of a thrombus are platelets, erythrocytes, and fibrin, each playing a critical role in determination of biological and physical properties of thrombi, such as …
