Deep Vein Thrombosis (DVT)

Doctor visit mandatory

With thrombosis, a blood clot (thrombus) blocks a blood vessel, causing only a little blood to flow through the vessel. Therefore, you must consult your doctor in case of any suspicion of a deep vein thrombosis.

Blood clots form primarily in the veins of the legs and pelvis. These blood vessels collect the blood from the feet, the legs and the pelvis and transport it back to the heart. A deep vein thrombosis must be treated by a doctor immediately.

The risk of a pulmonary embolism occurring is particularly high if the deep veins of the leg are affected. A thrombus in the affected vein becomes dislodged and is swept into the lung by the blood flow, where it can block a vessel. In contrast, if this happens in a superficial vein in the leg, the clot must first move in the direction of the deep leg veins, which is less risky.

The most common symptoms are:
  • Aching, dragging pain
  • Redness or blue discoloration of the skin
  • Feeling of tension and swelling
A blood clot can form if:
  • the blood's flow rate slows down, for example, during confinement to bed or on long-haul flights
  • the walls of the blood vessel have changed
  • the blood has a high clotting susceptibility

The blood flows more slowly in veins than in arteries, which is why thromboses occur above all in the veins. The deep veins in the calf and thigh are mostly affected by deep vein thrombosis (phlebothrombosis).

A thrombosis can occur in the groin, in the thigh, in the hollow of the knee, in the calf or in the sole of the foot. Standing and walking are then especially painful.
