Vascular Testing for Diabetic Foot Ulcers: Frequently Asked Questions

Are palpable pulses enough to rule out poor blood flow?

No. In high-risk patients, absent pulses can indicate no flow, but palpable pulses are never an indicator of sufficient flow. Objective testing is needed.

How often should arterial flow be assessed?

The talk by Desmond Bell recommends assessing arterial flow at every visit, not only at the first encounter. A quick check takes seconds.

What do guidelines say about vascular assessment?

Wound Healing Society guidelines call for ruling out arterial disease and examining the whole patient, including risk status, foot exam, and noninvasive vascular tests.

How common is amputation without vascular testing?

Approximately 50% of non-traumatic lower extremity amputations in the U.S. are reported to be done without any vascular testing.

Does seeing a podiatrist matter?

A Duke University study found that patients who saw a podiatrist had a lower risk of amputation, and multidisciplinary teams reduced it further.

What should be documented about vascular status?

Record the test performed, the result, the date, and any referral or revascularization decision. A structured documentation system keeps this visible across visits, and our diabetic foot care page covers the broader workflow.

What is TOBA?

A Time-Out Before Amputation is a pause to confirm vascular assessment, revascularization consideration, multidisciplinary input, and patient understanding. Read the full summary in Early DFU Care and Time-Out Before Amputation.
