“…Besides these methods, oscillometry can be used to determine lesions in peripheral arteries as well. The comparison of this method with the ABI measured by Doppler ultrasound showed the AUC to be greater (0.87-0.95) than that determined by oscillometry (0.80-0.93) [24,25].…”

“…Haemodynamic measures of PVR, toe systolic pressures, arterial blood flow rates, and tissue oxygenation of haemoglobin measured using digital pulse oximetry or DUS or standard or dynamic computed tomographic angiography (CTA) had good reliability and diagnostic specificity, ruling out false‐negative PAD diagnoses of stenosis or occluded arteries verified by DSA. Pulse wave velocity (PWV) measurements and ankle divided by brachial PWV were reliable haemodynamic measures, but screening and diagnostic validity were not reported .…”

Early reliable, valid screening, diagnosis, and treatment improve peripheral arterial disease outcomes, yet screening and diagnostic practices vary across settings and specialties. A scoping literature review described reliability and validity of peripheral ischaemia diagnosis or screening tools. Clinical studies in the PUBMED database January 1, 1970, to August 13, 2018, were reviewed summarising ranges of reliability and validity of peripheral ischaemia diagnostic and screening tools for patients with non-neuropathic lower leg ischaemia. Peripheral ischaemia screening and diagnostic practices varied in parameters measured such as timing, frequency, setting, ordering clinicians, degree of invasiveness, costs, definitions, and cutoff points informing clinical and referral decisions. Traditional ankle/brachial systolic blood pressure index <0.9 was a reliable, valid lower leg ischaemia screening test to trigger specialist referral for detailed diagnosis. For patients with advanced peripheral ischaemia or calcified arteries, toe-brachial index, claudication, or invasive angiographic imaging techniques that can have complications were reliable, valid screening, and diagnostic tools to inform management decisions. Ankle/brachial index testing is sufficiently reliable and valid for use during routine examinations to improve timing and consistency of peripheral ischaemia screening, triggering prompt specialist referral for more reliable, accurate Doppler, or other diagnosis to inform treatment decisions.

“…The study showed that pulse oximetry had a sensitiveity of 77% and a specificity of 97%. Joyce et al [14] and Ignjatović et al [15] used pulse oximetry to evaluate degree of limb ischemia in patients attending two surgi cal vascular units. They found that SaO 2 assessed by pulse oximetry was useful to determine the stage of functional ischemia and the success of revascularization.…”

Recent Aims: New diagnostic methods are needed to detect peripheral arterial disease easier than using the ankle-brachial index measured by Doppler devices. We investigated whether the use of pocket pulse oximeters could meet sensitivity and specificity criteria as screening method to detect significant peripheral arterial perfusion deficits. Methods: We measured oxygen saturation (SaO₂) at index fingers and great toes (on horizontal and elevated 30°) by a pocket pulse oximeter in 250 subjects with diabetes mellitus attending the outpatient clinic. A finger-to-toe SaO₂ gradient greater than 2% was considered abnormal. Ankle-brachial index was measured by a hand held Doppler device. Peripheral arterial disease was defined as an ankle-brachial index less than 0.9. Results: A total of 1392 (93%) valid SaO₂ readings were obtained. Twenty-seven (11%) patients were excluded due to not having measurable SaO₂ finger-to-toe gradients. A total of 223 patients were analyzed. Peripheral arterial disease was detected in 47 (21%) patients. A finger-to-toe SaO₂ gradient greater than 2% had sensitivity 42.6% (95% CI 30.0% - 55.3%), specificity 79.1% (95% CI 75.7% - 82.6%), positive predictive value 35.7% (95% CI 25.2% - 46.4%), negative predictive value 83.4% (95% CI 79.8 - 87.1), positive likelihood ratio 2.03 (95% CI 1.23 - 3.17) and negative likelihood ratio 0.73 (95% CI 0.54 - 0.93) to detect peripheral arterial disease. The area under the receiving operating characteristic curve ...
