Medical indication

Diagnostic fields of application
  • Support for poststenotic blood pressure measurement to determine the severity of peripheral arterial disease (PAOD)
  • Localization of stenoses and occlusions
  • Detection of venous insufficiency and thrombosis
  • Easier blood pressure measurement in shock patients and small children
  • Differentiation between testicular torsion and epididymitis
  • Blood flow confirmation in surgical procedures
Ankle Brachial Index (ABI)

This correlates with the degree of stenosis, e.g. e.g.:

systemic pressure 120 mmHg
- poststenotic pressure 80 mmHg

Pressure gradient 40 mmHg

Poststenotic blood pressure measurement with the 8 MHz probe

Poststenotic blood pressure measurement is particularly suitable for detecting and determining the severity of peripheral AVK.

To do this, the Doppler probe is used to locate the A. tibialis posterior or the A. dorsalis pedis, which is easy to localize.

The blood pressure cuff placed just above the ankle is inflated to over-systolic levels. When depressurizing the cuff, read the “poststenotic pressure” at the first audible Doppler sound.

This value is compared with the systemic pressure over the brachial artery obtained in the same way and the pressure gradient is calculated.

Why it is important to detect peripheral arterial disease (PAD) early:

  • About 12-14% of the world population are affected.
  • 20-50% of the population have no symptoms. They are asymptomatic and unlikely to go undiagnosed.
  • 50% of PAD amputees die within 4 years. 50% survive longer than 4 years.
Evidence of acute deep vein thrombosis

Detection of an acute deep vein thrombosis with the 4 MHz probe.

The detection of deep vein thrombosis is one of the most important Doppler applications.

For this purpose, the femoral vein is localized in the groin area with the 4 MHz probe and the patient is asked to breathe forcefully.

If the iliac vein is patent, the inspiratory pressure increases lead to a flow stop. In the case of a hemodynamically relevant stenosis, however, this respiratory dependence is absent.

The reason for this pathological flow is the high postthrombotic pressure, which causes a reduced but completely even venous return flow via the collaterals.
