According to the National Heart and Lung Institute, deep vein thrombosis, or DVT, is a blood clot that forms in a vein deep in the body.
Most deep vein blood clots occur in the lower leg or thigh. A blood clot in a deep vein can break off and travel through the bloodstream.

pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE.
