| Diabetes mellitus | 3 (27.3) |
| Hyperlipidemia | 6 (54.5) |
| Coronary heart disease | 3 (27.3) |
| Prior cerebral infarction | 2 (18.2) |
| Smoking history | 10 (90.9) |
| Current smoker | 5 (45.5) |
| Rutherford category | |
| II | 1 (9.1) |
| III | 9 (81.8) |
| IV | 1 (9.1) |
| Preoperative ABI | 0.45 (0.00-0.54) |
| Baseline SCr, μmol/L | 79.00 (65.85-88.53) |
| Baseline eGFR, mL/min/1.73 m2 | 95.33 (79.43-107.59) |
| CKD at baseline | 1 (9.1) |
| Renal artery disease on CTA | |
| Severe stenosis | 1 (4.5) |
| Preexisting occlusion | 1 (4.5) |
Values are presented as number only, number (%), median (interquartile range), or mean±standard deviation.
ABI, ankle-brachial index; SCr, serum creatinine; eGFR, estimated glomerular filtration rate; CKD, chronic kidney disease; CTA, computed tomography angiography.
CKD defined as eGFR <60 mL/min/1.73 m2 at baseline. Patient-level variables are reported for each patient (n=11). ABI was reported per limb (n=22) and renal artery disease on CTA per renal artery (n=22); percentages for both used 22 as the denominator.
