According to the 2023 American Diabetes Association Standards of Medical Care, the initial evaluation for PAD should include an assessment of the pedal pulses as well as a history of leg fatigue, claudication, and rest pain relieved with dependency. Patients who exhibit signs and symptoms of PAD should be referred for further arterial studies.
Although ankle-brachial index testing is indicated in patients with symptoms or signs of PAD, results may be inaccurate in patients with T2D owing to noncompressible vessels. Toe systolic blood pressure < 30 mm Hg is more accurate and suggestive of PAD.
Skin perfusion pressure (≥ 40 mm Hg), toe pressure (≥ 30 mm Hg), and/or transcutaneous oxygen pressure (TcPO2 ≥ 25 mm Hg) are tests that should be performed in patients with a diabetic foot ulcer and PAD.
According to guidelines by the Society for Vascular Surgery and the American Podiatric Medical Association, all individuals with diabetes who are > 50 years of age should undergo screening via noninvasive arterial studies.
