Vein where a blood clot has formed

• A. Thrombophlebitis
• B. Phlebitis
• C. Thrombosis
• D. Oedema

Answer: (A)

A vein with a blood clot formed and accompanying inflammation is described as thrombophlebitis. This term merges the idea of a thrombus (clot) with phlebitis (vein inflammation), which is exactly what happens when a clot develops inside a vein and the vein becomes inflamed. If there’s inflammation alone without a clot, that’s phlebitis; if there’s a clot but no explicit inflammation of the vein, that’s thrombosis. Oedema is simply swelling and not about the presence of a clot in a vein. In practice, areas with thrombophlebitis require caution in treatment and should be assessed medically before proceeding.
