Toe blood pressure and toe-brachial index

Area of Science:

• Vascular Medicine
• Noninvasive Diagnostic Techniques
• Peripheral Artery Disease (PAD)

Background:

• The Ankle-Brachial Index (ABI) is a common diagnostic tool for Peripheral Artery Disease (PAD).
• Medial arterial calcification can lead to falsely elevated ABI values, complicating diagnosis.
• Accurate assessment of lower extremity perfusion is crucial for timely PAD management.

Purpose of the Study:

• To highlight the utility of the Toe-Brachial Index (TBI) as a more accurate alternative to ABI.
• To emphasize TBI's effectiveness in patients with suspected medial arterial calcification.
• To promote the adoption of TBI by vascular nurses for improved PAD recognition.

Main Methods:

• TBI measurement is a noninvasive technique similar to ABI.
• Procedure involves using a sphygmomanometer and a hand-held Doppler device.
• Performed by nursing staff, facilitating widespread clinical application.

Main Results:

• TBI is considered more accurate than ABI in specific patient populations.
• TBI provides reliable lower extremity perfusion assessment when ABI is compromised by calcification.
• This technique aids in overcoming diagnostic limitations of ABI.

Conclusions:

• The Toe-Brachial Index (TBI) is a valuable tool for assessing lower extremity perfusion.
• Knowledge and application of TBI by vascular nurses can lead to earlier PAD diagnosis.
• Timely recognition and management of PAD through TBI can improve long-term patient outcomes.
