Diagnosis and treatment of peripheral arterial disease in CKD patients.

Peripheral arterial disease (PAD) is a cardiovascular disease risk equivalent and is a common problem in chronic kidney disease patients. Unlike in the general population, PAD in CKD occurs due to medial calcification as opposed to intimal atherosclerotic process. PAD intervention should be performed in select symptomatic patients, as described by the guidelines, and CVD risk factor modification should occur in all CKD patient, regardless of the presence of PAD. As a discipline, Interventional Nephrology has emerged out of a desire to create better outcomes for our patients and to "fix a problem." The core values of our discipline have evolved out of this fundamental desire to meet an unmet clinical need, to provide insight into a disease state specific to our patients, and to offer clinical/academic excellence in doing so. We must endeavor to follow a similar path in our approach to PAD. The purpose of this review is to educate interventional nephrologists in the diagnosis and treatment of PAD in their CKD patients.
