【摘要】目的研究阿托伐他汀预防全脑血管造影术(DSA)后急性肾损伤的应用价值。方法将行DSA的患者分为对照组(n=42)和干预组(n=42),干预组患者于术前2 d开始口服阿托伐他汀。分别于术前24 h及术后6 h、24 h、48 h抽血检测血中性粒细胞明胶酶相关脂质运载蛋白(NGAL)、胱抑素C(Cys C)和血肌酐(Scr)。结果两组患者术后6 h的血NGAL水平明显高于其他时间点,术后24 h Cys C水平明显高于其他时间点(P<0.05),对照组术后48 h Scr水平明显高于其他时间点(P<0.05);术后6 h干预组的血NGAL水平明显低于对照组 (P<0.05),术后24 h干预组的Cys C水平明显低于对照组(P<0.05),术后48 h干预组的Scr水平明显低于对照组(P<0.05)。术后对照组发生急性肾损伤患者8例(19.05%),干预组患者术后发生急性肾损伤患者2例(4.76%),干预组患者术后肾损伤发生率明显低于对照组,差异有统计学意义(P<0.05)。结论造影剂对肾脏功能有一定损伤作用,应用阿托伐他汀对肾脏有一定保护效果,有预防造影后肾损伤的作用。

【Abstract】ObjectiveTo study the clinical value of atorvastatin in the prevention of acute renal injury after digital subtraction angiography(DSA).MethodsPatients underwent DSA were divided into control group(n=42) and intervention group(n=42).The intervention group were given oral atorvastatin 2 days before operation.And then,neutrophil gelatinase-associated lipocalin(NGAL),cystatin C (Cys C) and serum creatinine(Scr)were detected 24 h before operation,6 h,24 h and 48 h after operation,respectively.ResultsAfter operation NGAL level 6 h in both groups were higher than those at other time points,Cys Clevel 24 h were higher than those at other time points(P<0.05),and the Scr level 48 h was significantly higher than those at other time points(P<0.05).The blood NGAL level 6 h after operation in the intervention group was significantly lower than that in the control group(P<0.05),the Cys C level 24 h after operation in the intervention group was significantly lower than that in the control group(P<0.05),and the Scr level 48 h after operation in the intervention group was significantly lower than that in the control group(P<0.05).After operation,8 cases (19.05%) suffered from acute kidney injury in the control group,and 2 cases (4.76%) suffered from it in the intervention group,the incidence of renal injury in the intervention group was significantly lower than that in the control group,so difference was statistically significant(P<0.05).ConclusionContrast media has some damages to renal function,atorvastatin can protect kidney and prevent renal injury after contrast.

目前,隨着全脑血管造影术(DSA)的广泛开展,造影剂在术中广泛应用,造影剂肾病(contrast-induced nephropathy,CIN)的发病逐年增加。有数据显示CIN已经成为医院获得性肾功能不全的第三位病因[1]。根据2005年欧洲泌尿生殖放射协会(ESUR)对比剂指南,造影剂肾病是指应用造影剂后新发生的、未发现其他原因的肾功能障碍或者原有的肾功能障碍加重:血肌酐(Scr)升高≥25%或者绝对值升高≥0.5 mg/dL(44.2 μmol/L)。如何预防甚至避免发生CIN,保护DSA患者的肾功能,是目前一个值得研究的问题。本研究探讨阿托伐他汀对CIN的影响,为临床预防发生DSA后CIN提供一定依据。endprint
