What are the signs and symptoms of deep venous thrombosis (DVT)?

The symptoms of deep vein thrombosis are related to obstruction of blood returning to the heart and causing a backup of blood in the leg. Classically, symptoms include:

  • pain,
  • swelling,
  • warmth, and
  • redness.

Not all of these symptoms have to occur. One, all, or none may be present with a deep vein thrombosis. The symptoms may mimic an infection or cellulitis of the arm or leg.

In the past health-care professionals would try to elicit a couple of clinical findings to make a diagnosis of a DVT in the leg. Dorsiflexion of the foot (pulling the toes towards the nose, or Homans' sign) and Pratt's sign (squeezing the calf to produce pain), have not been found effective in making a diagnosis. Now, health-care professionals don't usually rely upon whether these signs are present to make the diagnosis or decide that a DVT does not exist.

What are the signs and symptoms of superficial thrombophlebitis?

Blood clots in the superficial vein system most often occur due to trauma to the vein which causes a small blood clot to form. Inflammation of the vein and surrounding skin causes the symptoms similar to any other type of inflammation including

  • redness,
  • warmth,
  • tenderness, and
  • swelling.

Often the affected vein can be palpated (felt) as a firm, thickened cord. There may be inflammation that follows the course of part of the vein.

Although there is inflammation, there is no infection.

Varicosities can predispose to superficial thrombophlebitis and varicose veins. This occurs when the valves of the larger veins in the superficial system fail (the greater and lesser saphenous veins), allowing blood to back up and cause the veins to swell and become distorted or tortuous. The valves fail when veins lose their elasticity and stretch. This can be due to age, prolonged standing, obesity, pregnancy, and genetic factors.
