Arterial pressure measurement (ABI/TBI), bidirectional CW Doppler

Arterial pressure measurement, also known as the ankle-brachial index (ABI) and toe-brachial index (TBI), is a simple, non-invasive method for assessing blood flow in the extremities. Blood pressure measurements are taken on the arms and legs and compared with each other to indicate possible arterial occlusions. The bidirectional CW Doppler (Continuous Wave Doppler) uses ultrasound waves to visualize blood flow in the vessels and detect changes in blood flow patterns, which is helpful in diagnosing vascular diseases.

What is arterial pressure measurement (ABI/TBI)?

Arterial pressure measurement includes the ankle-brachial index (ABI) and the toe-brachial index (TBI), simple, non-invasive methods for assessing blood flow in the extremities. It involves taking blood pressure measurements on the arms and legs and comparing them to detect possible arterial occlusions.

How is arterial pressure measurement performed?

In arterial pressure measurement, blood pressure cuffs are placed on your arms and ankles (or toes). Blood pressure is measured in both areas, and the values are compared to assess circulation.

What is bidirectional CW Doppler?

Bidirectional CW Doppler is an ultrasound technique that uses continuous sound waves to visualize blood flow in the vessels. This method helps detect changes in blood flow patterns, which is helpful in diagnosing vascular diseases.

Why are ABI and TBI important examinations?

ABI and TBI are important examinations because they can detect arterial occlusions and circulatory disorders early on. This is crucial for the timely diagnosis and treatment of vascular diseases.

Is the examination painful?

Arterial pressure measurement and the use of bidirectional CW Doppler are usually painless. You may feel a slight pressure sensation from the cuffs or the ultrasound probe, but these sensations are usually well tolerated and of short duration.
