VENOUS THROMBOEMBOLISM Flashcards
is a blood clot that blocks the flow of blood.
A venous thromboembolism
means blood clot,
“Thrombo”
means a circulating particle that causes an obstruction.
Embolism
means in the veins
Venous
When healthcare providers talk about venous thromboembolism (VTE), they often talk about it as a disorder that can lead to two different kinds of blood clotting conditions:
deep vein thrombosisandpulmonary embolism
carry blood from the extremities of your body back to your heart.
Veins
Blood clot outside your body produces
scab
Blood clot intside your body produces
clot
A venous thromboembolism is not the type of blood clot that typically causes aheart attackorstroke. Those are usually caused by blood clots in your _____
arteries, not in your veins.
The most serious complications occur when a VTE breaks loose from where it formed, travels through your bloodstream, and gets stuck in the veins of your lungs.
pulmonary embolism(PE)
restricts oxygen and blood flow to your lungs while increasing blood pressure in your arteries.
Pulmonary embolism
Pulmonary embolism causes_____, which in turn can cause heart failure and death.
pulmonary hypertension
When a blood clot is stuck in your deeper veins, it’s called a
deep vein thrombosis(DVT)
A DVT that blocks the vein causes inflammation at the site of the blockage and can cause long-term damage to the vein, resulting in
chronic venous insufficiency(post-thrombotic syndrome).
thrombosis vs thromboembolism
A thrombosis is a blood clot.
A thromboembolism is a circulating blood clot that gets stuck and causes an obstruction.
Blood clots that occur in the smaller, superficial veins close to your skin____ don’t tend to cause the same kinds of complications.
(superficial venous thrombosis)
Virchow’s Triad
hypercoagulability
vascular damage
circulatory stasis
measure the level of D-dimer if elevated it indicates presence of a clot.
D-Dimer test
a protein fragment that your body makes when a blood clot dissolves in your body.
D-Dimer
Treatment of venous thromboembolism
Anticoagulant – Heparin and Warfarin
Thrombolytic Agent – dissolve blood clots by activating plasminogen
removal of the clot or placement of a vena cava filter to prevent the embolism from reaching the lungs and causing a P.E.
Thrombectomy
the extremity should be elevated in venous thromboembolism by placing a knee gatch or pillow under the knee.
