Deep vein thrombosis (DVT) is characterized by the formation of blood clots, known as thrombi, within one or more of the deep veins in the body, typically occurring in the legs. This condition can manifest as leg pain or swelling, although, in some cases, it may remain asymptomatic.

Certain medical conditions that influence the blood's clotting properties can increase the risk of developing DVT. Prolonged periods of immobility, such as during long-distance travel or when under extended bed rest due to surgery, illness, or accidents, can also contribute to the formation of blood clots in the legs.

DVT warrants attention due to its potential seriousness, as these clots can dislodge and travel through the bloodstream, becoming lodged in the lungs, obstructing blood flow, and leading to a pulmonary embolism. When both DVT and pulmonary embolism occur concurrently, it is referred to as venous thromboembolism (VTE).
