Obligatory medical device diagnostics
- Doppler sonography (ultrasound examination that can dynamically visualize fluid flows (especially blood flow)) or duplex sonography (ultrasound examination: combination of a sonographic cross-sectional image (B-scan) and the Doppler sonography method; medical imaging technique that can dynamically visualize fluid flows (especially blood flow)) of the lower leg veins (epi-, trans-, and subfascial, spontaneous and provoked signals; Valsalva maneuver) – to detect arterial and venous insufficiency.
- Ankle-brachial index (ABI; examination method that can describe the risk of cardiovascular disease); in this procedure, systolic blood pressure (first blood pressure value, in mmHg) is first measured at the ankle and upper arm on the supine patient. From these values, a quotient is then formed (ankle blood pressure / upper arm blood pressure) – if a peripheral arterial disease (pAVK) is suspected.
Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Photolethysmography (hemodynamic examination method used for diagnosis and follow-up of so-called chronic venous insufficiency (CVI)), phlebodynamometry (venous pressure measurement at rest and under stress), venous occlusion plethysmography (VVP; used to determine venous function) as functional examination methods of the leg veins
- Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based evaluation) or magnetic resonance imaging (MRI; computer-assisted sectional imaging procedure (using magnetic fields, that is, without X-rays)) of the lower leg.
- Intracompartmental pressure measurement – pressure measurement directly in the muscle cell in the lower leg.
- Capillary microscopy (method for detecting microcirculatory disorders, i.e. the circulatory disturbances in the capillaries).
- Lymphatic drainage scintigraphy, indirect lymphography.
- Laser Doppler fluxmetry (non-invasive method based on the Doppler effect that detects cutaneous microcirculation).
- Transcutaneous oxygen measurement
