Ankle-brachial index (ABI) measurement – assessment of peripheral arterial circulation
Measurement of the ankle-brachial index (ABI) is a non-invasive investigation used to evaluate arterial circulation at the level of the lower limbs and for early detection of peripheral arterial disease, frequently associated with diabetes mellitus.
Diabetes Mellitus
Ankle-Brachial Index (ABI) is an investigation used for assessment of peripheral arterial circulation and detection of peripheral arterial disease, a condition that can frequently occur in patients with diabetes mellitus, arterial hypertension, or dyslipidemia.
The test consists of comparing blood pressure measured at the ankle level with that measured at the arm level, using a sphygmomanometer and a Doppler device.
By calculating this index, it is possible to assess the degree of blood circulation at the level of the lower limbs and to identify any narrowing or blockage of the arteries.
Measurement of the ankle-brachial index is recommended for:
- detection of peripheral arterial disease
- assessment of arterial circulation at the level of the legs
- screening of patients with diabetes mellitus
- assessment of cardiovascular risk
- monitoring of patients with symptoms of peripheral ischemia
The investigation is rapid, non-invasive, and painless, being a useful method for screening and monitoring of vascular health.
Assessment of the ankle-brachial index is frequently included in monitoring of patients with diabetes mellitus, as it helps with early identification of vascular complications and prevention of diabetic foot syndrome.
The duration of the investigation is generally 10–15 minutes.
