Patients with end-stage liver disease frequently have baseline coagulopathies. The international normalized ratio is in common use for the estimation of bleeding tendency in such patients, especially those undergoing an invasive procedure like cardiac catheterization. The practice of international normalized ratio measurement-followed by pharmacologic (for example, vitamin K or fresh frozen plasma) or nonpharmacologic intervention-is still debatable. The results of multiple randomized trials have shown the superiority of the radial approach over femoral access in reducing catheterization bleeding. This reduction in bleeding in turn decreases the risk and cost of blood-product transfusion. However, there is little evidence regarding the use of the radial approach in the end-stage liver disease patient population specifically. In this review, we summarize the studies that have dealt with cardiac catheterization in patients who have end-stage liver disease. We also discuss the role of the current measurements that are used to reduce the risk of bleeding in these same patients.
终末期肝病患者常常存在基线凝血功能障碍。国际标准化比值常用于评估此类患者的出血倾向,尤其是那些接受诸如心导管插入术等侵入性操作的患者。国际标准化比值测量后进行药物治疗(例如维生素K或新鲜冰冻血浆)或非药物干预的做法仍存在争议。多项随机试验结果表明,桡动脉入路在减少导管插入术出血方面优于股动脉入路。出血的减少反过来降低了输血的风险和成本。然而,关于桡动脉入路在终末期肝病患者群体中的应用,几乎没有证据。在本综述中,我们总结了针对终末期肝病患者进行心导管插入术的研究。我们还讨论了当前用于降低这些患者出血风险的测量方法的作用。
