PURPOSE: To assess the incidence and predictors of acute renal failure after percutaneous transluminal angioplasty (PTA) in a cohort of patients with generalized atherosclerosis.
METHODS: A retrospective review of 213 consecutive patients (127 men; median age 71 years, interquartile range 63-77) undergoing femoropopliteal PTA was undertaken. Renal function was measured by creatinine clearance at baseline and 24 hours after the intervention; acute renal dysfunction was defined as > or = 20% decrease of creatinine clearance. The predictive value of potential risk factors was determined in a multivariate model adjusting for comorbidities, pre-existing renal impairment, and angiographic data.
RESULTS: Overall serum creatinine values and creatinine clearance remained stable within 24 hours after PTA. Acute renal dysfunction occurred in 25 (12%) patients. Two (1%) patients developed oliguria; one required transient hemodialysis and developed persistent renal failure. Pre-existing impaired renal function (OR 12.2, p < 0.0001) and contrast dosage (OR 1.1, p = 0.03) were independent predictors of acute renal failure; hypertension (OR 7.9, p = 0.06) and congestive heart failure (OR 4.5, p = 0.06) were associated factors.
CONCLUSIONS: While transient acute renal dysfunction occurs in approximately 10% of patients with peripheral artery disease within 24 hours after angioplasty, persistent renal failure or end-stage renal disease is rare.
