It is known that chronic kidney disease (CKD) is associated with increased postoperative morbidity and mortality in patients with peripheral artery disease who underwent lower extremity surgical revascularization; however, outcomes after peripheral vascular intervention (PVI) are less well established. This study sought to determine the impact of CKD on adverse outcomes in patients with peripheral artery disease who underwent PVI. Using data from the Veteran Affairs Clinical Assessment, Reporting, and Tracking System Program, we identified a cohort of 755 patients who underwent lower extremity PVI from June 2005 to August 2010 at 33 sites. The outcomes of interest were mortality, progression to dialysis, myocardial infarction, limb amputation, and stroke. Kaplan-Meier survival analysis and Cox proportional hazard frailty models assessed the association between CKD and adverse outcomes. Of the patients who underwent lower extremity PVI, 201 patients (27%) had CKD. The presence of CKD was associated with decreased survival (5-year survival probability of CKD compared with non-CKD: 49.9% [41.6% to 59.9%] vs 80.1% [76.2% to 84.1]), which persisted after risk adjustment (HR 1.57; 95% confidence interval 1.13 to 2.19). In addition, there was a significant association between CKD and progression to dialysis (HR 6.62; 95% confidence interval 2.25 to 19.43). In contrast, there was no association between CKD and re-hospitalization for myocardial infarction, limb amputation, or stroke. In conclusion, CKD is present in 1 of 4 patients who underwent PVI and is associated with increased risk of mortality and progression to dialysis.
