What is DVT and how dangerous is it?

ANSWER

DVT stands for deep vein thrombosis, a blood clot in one of your body's deep veins, usually within a muscle of your leg.

The biggest danger is that part of the clot could break off and travel to your lungs. It could cause a blockage known as a pulmonary embolism, or PE. Your doctor will talk to you about how likely that is to happen with your clot.
