To compare the clinical outcomes in patients with chronic renal insufficiency (CRI) and renal artery stenosis (RAS) following renal artery (RA) stent placement with and without embolic protection device (EPD) usage.
Eighteen patients who had RA stent placement with EPD were matched to control patients (RA stent only). Blood pressure, number of hypertensive medications, and estimated glomerular filtration rate (eGFR) at 3 months before the procedure and after 12 months were determined. An increase of ≥ 20% in eGFR at 12 months from baseline was defined as "improvement," decrease of ≥ 20% as "deterioration," and an eGFR change between those values as "stabilization" at 12 months.
At 12 months, stage 4 patients treated with EPD had significantly higher eGFR than controls (P = .01). There was no statistical difference in blood pressure outcomes between the 2 groups.
Patients with stage 4 CRI did significantly better with EPD than those treated without it.
比较使用和不使用栓塞保护装置（EPD）进行肾动脉（RA）支架置入术后，慢性肾功能不全（CRI）合并肾动脉狭窄（RAS）患者的临床结局。
将18例使用EPD进行RA支架置入的患者与对照患者（仅行RA支架置入）进行匹配。测定术前3个月及术后12个月的血压、抗高血压药物数量和估计肾小球滤过率（eGFR）。12个月时eGFR较基线水平升高≥20%定义为“改善”，降低≥20%定义为“恶化”，介于两者之间的eGFR变化定义为12个月时“稳定”。
12个月时，使用EPD治疗的4期患者eGFR显著高于对照组（P = 0.01）。两组血压结局无统计学差异。
4期CRI患者使用EPD的效果明显优于未使用者。
