Is there a connection between the deep vein thrombosis and pulmonary embolism?

Absolutely: When a person gets a deep venous thrombosis (dvt), part of the thrombus (blood clot) can break off and travel to the lungs. This is what we call a pulmonary embolism (pe). Although it has been shown that it is possible to form a pe without having a DVT first, it is felt that this is a very uncommon occurrence. Far more commonly, a pe will start out as a DVT in one or both legs.

Yes: Thrombus (clot) within the deep veins of the legs, arms, and pelvis may travel to the pulmonary arteries in the lungs and cause pulmonary embolism.
