“…Of those with diabetes and peripheral neuropathy, 23.2% also had PVD. There were several participants with an ankle pressure ≥ 300 mmHg due to incompressibility of the arteries [23] (KDM = 9, NDM = 3, IGT = 3, IFG = 1 and NGT = 2), and of these participants three were classified with PVD using the ECQ.…”

“…Diabetic patients with end-stage renal disease are likely to have falsely elevated ABPI levels (10,11), and ABPI measurements are less able to detect occlusion in arterial segments distal to the ankle, which might be detected by palpation of distal pedal pulses. Therefore, we used a combination of criteria to define subjects with PAD.…”

OBJECTIVETo evaluate the prevalence of lower-limb complications in a multiracial cohort of patients with diabetes receiving dialysis.RESEARCH DESIGN AND METHODSThis work was a cross-sectional study of lower-limb complications in dialysis-treated patients with diabetes in the U.K. and U.S.RESULTSWe studied 466 patients (139 U.K.; 327 U.S.). The prevalence of lower-limb complications was high (foot ulcers 12%, neuropathy 79%, peripheral arterial disease 57%, history of foot ulceration 34%, and prior amputation 18%), with no significant ethnic variation, except that foot ulcers were more common in whites than in patients of African descent (P = 0.013). Ninety-five percent of patients were at high risk of lower-limb complications. Prior amputation was related to foot ulcer history, peripheral arterial disease, and hemodialysis modality in multivariable analysis. Prevalent ulceration showed independent associations with foot ulcer history and peripheral arterial disease, but not with ethnicity.CONCLUSIONSAll patients with diabetes receiving dialysis are at high risk of lower-limb complications independent of ethnic background.

“…The ankle-brachial index (ABI) is a useful screening test, but is less reliable in diabetic patients who exhibit arterial calcification (5,6). Moreover, it is generally unable to determine the precise location and severity of vascular stenosis, so that an additional imaging test is needed prior to revascularization.…”

“…PERIPHERAL ARTERIAL DISEASE (PAD) has increased prevalence in older populations, smokers, and diabetics, and is associated with systemic atherosclerosis and cardiovascular morbidity (1)(2)(3)(4). The ankle-brachial index (ABI) is a useful screening test, but is less reliable in diabetic patients who exhibit arterial calcification (5,6). Moreover, it is generally unable to determine the precise location and severity of vascular stenosis, so that an additional imaging test is needed prior to revascularization.…”

Purpose To evaluate the signal properties of 2D time of flight (TOF), quiescent-interval single-shot (QISS), ECG-gated 3D fast spin-echo (FBI), and ungated 3D fast spin-echo ghost (Ghost) magnetic resonance angiography (MRA) over a range of flow velocities in a pulsatile flow phantom with a 50% diameter stenosis at 1.5T. Materials and Methods Blood-mimicking fluid was pumped at eight peak flow velocities through a stenotic region in triphasic and monophasic waveforms. Vascular signal proximal, within, and distal to the stenosis was measured from the source images of the four MRA methods. Coronal maximum intensity projection images were used to compare image quality. Results TOF and QISS signal trends were similar, but QISS exhibited the most consistent signal across velocities. At high velocities (≥42.4 cm/s), TOF showed post-stenotic signal loss that was not observed with QISS. FBI and Ghost signals peaked at low velocities (3.9–9.7 cm/s) without flow compensation and at high velocities (≥64.6 cm/s) with flow compensation. Conclusion FBI and Ghost demonstrated dependence on blood flow velocity and flow compensation. TOF was sensitive to flow artifacts at high velocities. QISS proved most robust for accurately depicting the normal lumen and stenosis under a wide range of flow conditions. Monophasic and triphasic flow did not appreciably affect the signal performance of any method.
