Thrombosis

Thrombosis refers to a blood clot formed in a deep vein of the legs, arms, or pelvic region.
The blood clot partially or completely occludes the veins, thus preventing normal blood return to the heart. There is a risk that the thrombus may grow and dislodge, floating into the lungs and embolizing the pulmonary vessels.
The typical symptoms of thrombosis include unilateral acute swelling of the limb, pain, warmth, and redness of the skin. However, sometimes thrombosis may go unnoticed.
Thrombosis is always an emergency situation requiring immediate medical attention. The goal of early treatment is to prevent the growth of the blood clot, restore normal blood flow, and prevent life-threatening complications such as a pulmonary embolism. This is achieved through therapeutic anticoagulation.
As a result of deep vein thrombosis, chronic drainage disorders may develop due to damaged venous valves that have lost their function as a result of the thrombosis or due to incomplete recanalization due to connective tissue remodeling of the thrombus.
A symptomatic chronic venous insufficiency resulting from deep vein thrombosis is referred to as post-thrombotic syndrome (to link).
