What causes a DVT to break off?
Venous clots most often happen in the deep veins of the legs. This is called deep vein thrombosis (DVT). Once a clot has formed in the deep veins of the leg, there is a potential for part of the clot to break off and travel through the blood to another area of the body, often the lung.

What can happen if a DVT is left untreated?
The most serious risk of untreated DVT is a pulmonary embolism. This occurs when a blood clot breaks loose and travels to the lungs. It is an emergency situation and can be fatal. A pulmonary embolism can restrict blood flow to the heart, causing a strain that results in heart enlargement.

How do they check for DVT?
Duplex ultrasonography is an imaging test that uses sound waves to look at the flow of blood in the veins. It can detect blockages or blood clots in the deep veins.
