Medical Conditions - Thrombus

A thrombus is a blood clot that forms in the veins or arteries, remains there, and restricts blood flow. A thrombus can be caused by various factors, including disease or injury to leg veins, immobility, a broken bone, obesity, certain medications, and autoimmune disorders. Symptoms of a thrombus include pain or discomfort, heaviness in the affected area, swelling, itchiness, or warmth near the clot. Anticoagulants such as heparin or low-molecular-weight heparin are used to prevent the formation of new blood clots.
