ABI

Also written as: ABI — ankle-brachial index

Ratio comparing blood pressure in ankle to arm, used to diagnose peripheral arterial disease.

Full Definition

Ankle-brachial index is a non-invasive diagnostic test that compares systolic blood pressure measurements at the ankle and arm to assess for peripheral arterial disease. Normal values range from 0.9-1.3, with values below 0.9 indicating arterial insufficiency. This measurement is fundamental in vascular surgery documentation and requires consistent formatting and interpretation guidelines in clinical reports.

Usage

Usage note: Always hyphenate the full form as 'ankle-brachial index'.

In Context

  • "Pre-operative ABI was 0.45 on the right and 0.52 on the left." — Clinical assessment
