J Endovasc Ther:血管成形术治疗CLI后的重复干预会增加截肢风险

2016-07-06 Seven L 译 MedSci原创

近期有研究表明,对于膝下血管成形术治疗严重肢体缺血(CLI)后的重复干预的需要,可能增加未来重大截肢风险。 来自日本的研究人员对1065名患者的1298个肢体进行了研究分析,患者的平均年龄为72岁,739为男性。在平均随访1.2年(四分位距为0.4-2.5),11%的肢体进行了重大截肢。38%的需要重复干预,其中72例需要旁路手术和427例需要重复血管成形术。Kaplan-Meier第2年重复干预

近期有研究表明,对于膝下血管成形术治疗严重肢体缺血(CLI)后的重复干预的需要,可能增加未来重大截肢风险。

来自日本的研究人员对1065名患者的1298个肢体进行了研究分析,患者的平均年龄为72岁,739为男性。在平均随访1.2年(四分位距为0.4-2.5),11%的肢体进行了重大截肢。38%的需要重复干预,其中72例需要旁路手术和427例需要重复血管成形术。Kaplan-Meier第2年重复干预和重大截肢率为49.2%。

研究人员采用混合效应,确定重复干预和未来重大截肢风险之间有显著的关联(未经调整的HR = 3.01;95% CI,2.05-4.41)。

重复干预与常规透析患者未来更大的重大截肢风险有关(HR = 3.35; 95% CI, 2.14-5.26)。不过对于非透析患者,两者间不存在联系。(HR = 1.67; 95% CI, 0.71-3.93)。

据研究人员介绍,“透析患者的重大截肢风险很高,当他们需要再次介入、重复干预时,是不可能降低截肢风险的。”

除了以上结果以外,研究者还发现,1年内重复干预与更高的组织损失率、感染率、定期透析和不能行走的状态有关。1年内需要重复干预患者的1年重大截肢率估计为11.2%。
