What is the potential consequence of deep vein thrombosis?

Deep vein thrombosis (DVT) primarily involves the formation of a blood clot in a deep vein, usually in the legs. The condition arises when blood flow slows down or becomes stagnant, leading to clot formation. This clot can cause swelling, pain, and can occlude blood flow in the affected area.

Understanding this condition is critical, as it highlights that the formation of a blood clot is a primary defining feature of DVT. Furthermore, if the clot dislodges, it can travel to the lungs, resulting in a pulmonary embolism, which is a serious complication stemming from the original condition. Recognizing the connection between DVT and clot formation is vital for understanding the risks associated with it and the importance of prompt medical intervention.
