What is the triad for venous thrombosis?
Over a century ago, Rudolf Virchow described 3 factors that are critically important in the development of venous thrombosis: (1) venous stasis, (2) activation of blood coagulation, and (3) vein damage. These factors have come to be known as the Virchow triad.
What is the Virchows Triad?
The Virchow triad is an organizational structure that shows risk factors for and etiologies of thrombus formation. Anything that makes a patient more likely to form a thrombus can fit into this schematic. The three “points” of the triad are endothelial injury, abnormal blood flow, and hypercoagulability.
What 3 factors contribute to venous thrombus formation?
Obesity and Venous Thromboembolism In his eponymous triad, Virchow described the three categories of factors which contribute to thrombosis: hypercoagulability, haemodynamic changes (stasis, turbulence) and endothelial injury (Figure 17.2).
What is the Virchow triad that leads to deep vein thrombosis DVT?
As it is has come to be known today, the triad consists of stasis, vessel damage, and hypercoagulability, and is used to describe the etiology and assess the risk of thrombosis, especially of deep vein thrombosis (DVT.)
What causes Virchows Triad?
The three factors of Virchow’s triad include intravascular vessel wall damage, stasis of flow, and the presence of a hypercoagulable state.
What is venous intimal damage?
This is due to any factor which slows or obstructs the flow of venous blood. One of the most common causes is endothelial (intimal) damage secondary to intrinsic or secondary to external trauma. In a hypercoagulable state, a biochemical imbalance between procoagulant and anticoagulant factors occur.
What is the best treatment for DVT?
DVT is most commonly treated with anticoagulants, also called blood thinners. These drugs don’t break up existing blood clots, but they can prevent clots from getting bigger and reduce your risk of developing more clots. Blood thinners may be taken by mouth or given by IV or an injection under the skin.

How does Virchow’s triad contribute to deep venous thrombosis?
The three elements that make up the Virchow’s triad contribute to the development of a deep venous thrombosis. However, one element of the triad may contribute more than the others. Also, platelet dysfunction is not part of the Virchow’s triad. Endothelial injuries are secondary to injury, trauma, or surgery.
Where does deep vein thrombosis ( DVT ) usually occur?
Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in a deep vein. These clots usually develop in the lower leg, thigh, or pelvis, but they can also occur in the arm. It is important to know about DVT because it can happen to anybody and can cause serious illness, disability, and in some cases, death.
Is the triad the same as the cause of thrombosis?
While both Virchow’s and the modern triads describe thrombosis, the previous triad has been characterized as “the consequences of thrombosis”, and the modern triad as “the causes of thrombosis”.
