Eur J Vasc Endovasc Surg:肢体缺血患者术前贫血会导致其更高的死亡风险

2016-05-29 Seven L MedSci原创

近期研究结果表明,肢体缺血患者在接受治疗前存在贫血,那么其术后有更大的短期和长期风险。不管进行血管重建术的类型,还是独立的其他危险因素,这种风险的增加均是存在的。该研究纳入了2005至2013之间的403例患者(平均年龄73岁;73%为男性)接受了血管内(n = 212)或开放手术(n = 191)治疗严重肢体缺血(CLI)的患者。获取患者治疗前血红蛋白水平,以评估术前是否存在贫血(男性:小于13

近期研究结果表明,肢体缺血患者在接受治疗前存在贫血,那么其术后有更大的短期和长期风险。不管进行血管重建术的类型,还是独立的其他危险因素,这种风险的增加均是存在的。

该研究纳入了2005至2013之间的403例患者(平均年龄73岁;73%为男性)接受了血管内(n = 212)或开放手术(n = 191)治疗严重肢体缺血(CLI)的患者。获取患者治疗前血红蛋白水平,以评估术前是否存在贫血(男性:小于13 g/dL;女性:小于12 g/dL)。平均随访30个月,以短期和长期存活作为研究的主要终点。

数据显示,术前贫血占75%,院内或治疗30天内的死亡率为8%,两组之间无差异(8.5% vs. 7.3%)。当血红蛋白为10 g/dL时,有最佳的短期生存预测效果,接受者操作特征曲线分析其判别能力为0.665(95% CI,0.6-0.8)。术前血红蛋白水平低于10 g/dL的占22%,短期死亡率在这类患者中明显更高(17.7% vs. 5.1%;aOR=3.9; 95% CI, 1.8-8.4)。

对391名有可用随访数据的患者分析后发现,1年和5年生存率分别为77%和45%,不同手术类型间不存在差异。术前血红蛋白水平低于10 g/dL的患者无论是1年生存(55% vs. 83%)还是5年生存(21% vs. 53%;aHR=2.5; 95% CI, 1.8-3.4)均显著更低。

血管内治疗组患者的分析显示,无术前是否贫血,患者短期生存率无显著差异(P = .363),但是较低血红蛋白水平患者的长期生存率较差(P < .001)。在开放性手术组中,术前贫血患者的短期和长期死亡率均更高(两者P均 < .001 )。

“术前贫血被确定为肢体缺血患者短期和远期死亡率的一个危险因素,而不管其他风险因素和血管重建技术的类型,”研究人员写道,“建议术前对患者的贫血进行治疗, 但是该类患者术前贫血的最佳管理仍不清楚。”
