Leg Pain: Diagnostic Tests

Obligatory medical device diagnostics

  • Compression phlebosonography (KUS, synonym: vein compression sonography); sonography (ultrasound examination) to document and check the compressibility of the deep veins in the legs and arms) – in cases of suspected deep vein thrombosis (DVT); very safe procedure especially in cases of thrombi of the femoral veins or popliteal vein [gold standard].
  • Color-coded duplex sonography – for suspected thrombi in the hollow/pelvic veins.

Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.

  • Doppler sonography (color-coded duplex sonography)* – ultrasound procedure, which can assess in particular the blood flow in the vessels.
  • Phlebography (representation of the veins by means of contrast medium administration in conventional X-ray) – indicated in sonographically unclear findings.
  • Venous occlusion plethysmography – indicated for course assessment, if necessary.
  • Magnetic resonance phlebography (MR phlebography) – indicated for suspected abdominal/pelvic thrombi.
  • Sonography (ultrasound examination) of the affected body region – to assess tissue changes.
  • Light reflection rheography – for suspected chronic venous insufficiency (CVI).
  • Arthrosonography (ultrasound examination of joints) – in arthrosonography, both the soft tissues and superficial areas of the bones of a joint can be displayed (implementation, for example, in unclear joint swelling); if necessary, puncture of the joint under sonographic view.
  • X-ray diagnostics of the joint, in two planes – in arthralgia (joint pain).

* Caveat. Lipedema and venous insufficiency (chronic venous congestion syndrome, CVI)/varicosis (varicose veins) have a very high coincidence (coincidence, -meeting of two events), so that the venous status – in the sense of a differential diagnosis – should be clarified by duplex sonography. Under the guise of lipedema, for example, postthrombotic syndrome (PTS) may also be hidden.
