What is the most important factor in Virchow's triad of thrombosis?

What is the most common type of venous thrombosis?
Most commonly, venous thrombosis occurs in the "deep veins" in the legs, thighs, or pelvis (figure 1). This is called a deep vein thrombosis, or DVT. DVT in the leg is the most common type of venous thrombosis. However, a clot can form anywhere in the venous system.
Which factor is included in the Virchow triad select all that apply one some or all responses may be correct?
The answers are C, D, and E. Virchow's Triad details the THREE factors (hence why it called a triad) for blood clot formation within the vessel. Remember “SHE”: Stasis of Venous Blood, Hypercoagulability (means excessive coagulability), Endothelial damage.
What is triad of the primary phase of hemostasis?
Hemostasis is a sequence of events that leads to bleeding cessation via the formation of a fibrin-platelet hemostatic plug. It involves the triad of an injured vascular wall, platelets, and coagulation cascade.
What 3 factors contribute to venous thrombus formation?
These factors have now come to be known as “stasis” and “hypercoagulability” respectively, which are two of the three tenets of Virchow's Triad.4 Gabriel Andral, who is considered the founder of hematology, observed in 1830, decades before Virchow, that stasis, inflammation of the endothelium, and an increased tendency ...
What causes venous thrombosis?
The main causes of deep vein thrombosis (DVT) are damage to a vein from surgery or inflammation and damage due to infection or injury.
What is Phlegmasia Cerulea Dolens?
Phlegmasia cerulea dolens is an uncommon, severe form of deep venous thrombosis (blood clots in the vein). It most often occurs in the upper leg.
What is venous thrombosis?
Venous thromboembolism (VTE), a term referring to blood clots in the veins, is an underdiagnosed and serious, yet preventable medical condition that can cause disability and death.
Which of the following is the most frequent site of venous thrombosis?
Conclusions: Our study showed that the most common site of DVT was the muscular calf vein.
What are the types of thrombosis?
There are 2 main types of thrombosis:Venous thrombosis is when the blood clot blocks a vein. Veins carry blood from the body back into the heart.Arterial thrombosis is when the blood clot blocks an artery. Arteries carry oxygen-rich blood away from the heart to the body.
What is venous stasis?
Venous stasis involves an inflammation of the skin in the lower legs as a result of chronic venous insufficiency. If the valves or walls of the veins in the legs are not working properly, it is difficult for blood to circulate from the legs back to the heart.
What is flow stasis?
Stasis: A stoppage or slowdown in the flow of blood or other body fluid, such as lymph.
What is blood flow stasis?
What Does That Mean? Blood stasis is a term used by some Eastern medical practitioners meaning that the blood is not flowing or circulating as optimally as it could to all parts of the body. It is considered to be one of the major causes of pain.
What 3 factors contribute to venous thrombus formation?
According to Virchow's triad,5 there are three possible contributors to the formation of an abnormal clot (thrombus): vessel wall injury or inflammation, changes in the intrinsic properties of blood, and decrease in blood flow velocity (Figure 1).
What are the factors that contribute to thrombosis?
Virchow's triad or the triad of Virchow ( / ˈfɪərkoʊ /) describes the three broad categories of factors that are thought to contribute to thrombosis. Hypercoagulability. Hemodynamic changes (stasis, turbulence) Endothelial injury/dysfunction. It is named after the renowned German physician Rudolf Virchow (1821-1902).
When was the term "Virchow's Triad" first used?
This eponym did not emerge in the literature until long after Virchow's death. One estimate of the first use of the phrase dates it to the early 1950s.
What is a stasis in medical terms?
Stasis. The first category, alterations in normal blood flow, refers to several situations. These include venous stasis, long surgical operations, prolonged immobility (whilst on a long plane or car ride, bed bound during hospitalization), and varicose veins. The equivalence of Virchow's version and the modern version has been disputed.
Did Virchow have endothelial injury?
Although the concept of the triad is usually attributed to Virchow, he did not include endothelial injury in his description. This has been attributed to a dispute Virchow had with Jean Cruveilhier, who considered local trauma of primary importance in the development of pulmonary artery thrombosis.
Who discovered pulmonary embolism?
Rudolf Virchow elucidated the etiology of pulmonary embolism, whereby thrombi occurring within the veins, particularly those of the extremities, become dislodged and migrate to the pulmonary vasculature. He published his description in 1856. In detailing the pathophysiology surrounding pulmonary embolism, he alluded to many ...
Did Virchow propose a triad?
However, the elements comprising Virchow's triad were not proposed by Virchow. Neither did he ever suggest a triad to describe the pathogenesis of venous thrombosis. In fact, it was not until decades after Virchow's death that a consensus was reached proposing that thrombosis is the result of alterations in blood flow, vascular endothelial injury, ...
