Abstract
Aims: We aimed to determine the relative risk of pedal vessel calcification (PVC) on major adverse foot events (MAFEs) and chronic kidney disease (CKD) stage in patients with diabetes mellitus (DM) and peripheral neuropathy (PN).
Methods: Retrospective electronic medical record review of 152 patients with diagnoses of DM, PN, and CKD stages 1–5 who had at least one foot x-ray obtained. PVC was scored (from 0–4) based on foot anatomic location and radiology reported MAFEs, which includes foot fracture, Charcot neuroarthropathy, foot ulcer, osteomyelitis, or minor amputation. Risk ratios (RR) with 95% confidence intervals (95% CI) and Poisson regressions were performed assessing the risk of sustaining MAFEs with number of PVCs and stage of CKD.
Results: The risk of any MAFE increased as PVC score increased (RR = 1.23); the risk of any MAFE increased as CKD stage increased (RR = 1.35); and risk of any PVC increased as CKD stage increased (RR = 1.71).
Conclusions: Pedal vessel calcification (PVC) on a foot radiograph increases the risk of any MAFE and increases with progressive stage of CKD. PVC may serve as a gateway to prompt investigation, treatment, or referral for at-risk diabetic neuropathic, nephropathic patients.
