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. How genetic defects in natural anticoagulant mechanisms and abnormalities in procoagulant factors can predispose to venous thrombosis. ACL TOP ® Family 50 Series .
