Deep vein thrombosis, or DVT, is essentially a blood clot that forms in one of the deep-lying veins in the body. Blood clots can form when blood thickens or becomes clumped together, which can occur if the vein wall becomes damaged, from poor circulation or having an increased likelihood to form clots from heredity, hormones or birth control pills.
Most of the deep vein blood clots form in the lower body particularly the legs, pelvic or abdominal regions, but they can also occur anywhere in the body.
A blood clot that breaks away from the vein wall and travels through the veins is known as an embolus. Emboli are particularly concerning to vascular doctors in Long Island because the clot can flow through the veins and into major organs, diminishing or blocking the blood supply to the major organs such as the heart, brain or lungs. Pulmonary embolism (PE), for example, is a life-threatening blood clot lodged in the lung.
