Venous thrombosis
Venous thrombosis is the formation of a clot in a vein. The deep form (DVT) causes swelling and pain in one leg and its main risk is pulmonary embolism; the superficial form (phlebitis) is milder but also deserves assessment.
In this section we bring together articles to recognise a clot in the leg, tell phlebitis apart and understand tests such as the D-dimer. The treatment is on the venous thrombosis page.
