Question 4#

Virchow triad is characterized by:

a. Stasis
b. Endothelial damage
c. Hypercoagulability
d. All of the above

Correct Answer is D


Three conditions, first described by Rudolf Virchow in 1862, contribute to VTE formation: stasis ofblood flow, endothelial damage, and hypercoagulability. Of these risk factors, relative hypercoagulability appears most important in most cases of spontaneous VTE, or so-called idiopathic VTE, whereas stasis and endothelial damage likely play a greater role in secondary VTE, or so-called provoked VTE, occurring in association with transient risk factors such as immobilization, surgical procedures, and trauma.
