Purpose
To evaluate the effect of chronic kidney disease (CKD) on all-cause mortality, major adverse limb event (MALE), MALE + POD (post-procedure death), and amputation after endovascular treatment of superficial femoral (SFA) or popliteal arterial atherosclerotic disease.
Materials and Methods
A retrospective review from January 2002 to October 2011 was performed of four hundred forty patients who underwent endovascular treatment of symptomatic SFA or popliteal atherosclerotic disease for claudication (N=251) or critical limb ischemia (CLI) (N=267). CKD stage was divided based on the Kidney Dialysis Outcomes Quality Initiative (KDOQI) classification. The outcomes and factors associated with amputation, MALE, and MALE + POD were determined.
Results
Patients with a diagnosis of diabetes [HR=2.2; 95% CI (1.3–3.6), P=0.002] and a run off score of 0 or 1 [HR=2.0; 95% CI (1.2–3.4), P=0.01] relative to run off score of 3 were at increased risk of amputation. A patient with a baseline GFR of less than 45 had a 17% increase in amputation for every 5 point decrease less than 45 [95% CI (1.09–1.26), P<0.001]. An increase of 10 years in age, [HR=1.9, 95% CI (1.5–2.3), P<0.001], a TASC class of C/D relative to A/B [HR=1.6, 95% CI (1.1–2.2), P=0.01], and CLI [HR=2.4, 95% CI (0.5–0.9), P<0.001] were associated with increased mortality. A female gender was associated with a decreased risk of mortality [HR=0.7, 95% CI (0.5–0.9), P=0.01)].
Conclusion
Worsening CKD is associated with higher amputation rates, all-cause mortality, and MALE + POD in patients undergoing endovascular treatment of SFA or popliteal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
