Definition & Meaning of "deep vein thrombosis"

What is "deep vein thrombosis"?

Deep vein thrombosis (DVT) is a condition where a blood clot forms in one of the deep veins of the body, typically in the legs. This clot can partially or completely block blood flow, leading to symptoms such as swelling, pain, warmth, and redness in the affected area. DVT can be caused by factors like prolonged sitting, immobility, injury to the veins, or underlying medical conditions that affect blood clotting. If a blood clot breaks loose and travels to the lungs, it can cause a life-threatening condition called pulmonary embolism. Treatment for DVT usually involves blood-thinning medications to prevent the clot from growing or breaking off, along with actions to prevent more clots from forming.
