Insight into the pathogenesis of thrombotic disorders began with the 19th century pathologist Rudolf Virchow, whose clinical and postmortem observations led him to postulate that the formation of blood clots sufficiently large to occlude major blood vessels was dependent upon three independent processes: + + Abnormal blood flow—principally stasis. Thrombotic disorders. The relative risks of VTE were 10.6 (95% CI, 5.6–20.4) and 2.9 (95% CI, 1.0–8.6) for factor V Leiden and prothrombin G20210A, respectively. Vascular damage .
