Swelling, a feeling of tightness or pain in one leg can be a sign of a blood clot in a deep leg vein (deep vein thrombosis). With compression ultrasound we can check for this directly in our practice: quickly, with little discomfort and without radiation.

How does the examination work?
We follow the deep veins with the ultrasound probe from the groin along the thigh to the back of the knee and, depending on the question, into the lower leg. At many points we gently press the vein together with the probe. A healthy vein can be compressed completely. If it stays open despite the pressure, this indicates a clot.
The examination usually takes 10 to 20 minutes. No preparation is needed. Comfortable clothing that is easy to take off is helpful.
When is the examination useful?
- if one leg is swollen, painful or feels tight in the calf or thigh
- if such symptoms appear after immobilisation (e.g. a plaster cast), an operation or a long journey
- to monitor the course of treatment of a known thrombosis
After the examination
We discuss the result with you straight away. If a thrombosis is found, we usually start treatment immediately. If you suspect a thrombosis, please call us on the same day if possible.
Important: If you also have sudden shortness of breath, chest pain or are coughing up blood, call the emergency number 112 immediately.
