Survival following renal artery stent revascularization: four-year follow-up

J Invasive Cardiol. 2004 Jul;16(7):368-71.

Abstract

To evaluate survival following renal artery stenting, 72 consecutive patients (Mean age 69 +/-10 years, 72% African-American) were retrospectively evaluated over a 4-year period. Complete follow-up was available in 97% patients (70/72). Twelve patients (12/70 = 17%) died; 2 procedure-related (renal stent = 1, coronary stent = 1), one cancer-related and 9 cardiac. The overall survival at a mean follow-up of 31 +/- 13 months was 83%. Eight patients (8/70 = 11%) were eligible for 1 year, 25/70 (36%) for 2 year, 16/70 (23%) for 3 year, 21/70 (30%) for 4 years (or longer) follow up. Five patients died within 1 year, three during the second year, three during the third year and 1 patient after the forth year. Abnormal baseline serum creatinine, male gender, bilateral renal artery stenosis and systolic dysfunction were associated with statistically significant lower survival.
