What is deep vein thrombosis (DVT) characterized by?

Deep vein thrombosis (DVT) is characterized by the formation of blood clots in the deep veins, most commonly in the legs. This condition can lead to significant health complications, including pulmonary embolism if a clot dislodges and travels to the lungs. The key feature of DVT is the accumulation of blood cells, platelets, and fibrin that precipitate in the venous system, creating a thrombus or clot, which can obstruct blood flow. Understanding DVT is crucial for recognizing symptoms such as swelling, pain, and redness in the affected area, and for implementing timely interventions to prevent serious outcomes.
