Patients with liver cirrhosis often exhibit complex alterations in their hemostatic system that can be associated with both bleeding and thrombotic complications. While prophylactic correction of abnormal coagulation parameters should be avoided, an individualized approach is recommended prior to invasive procedures, whereby specific preventive measures to stabilize hemostasis should be based on the periprocedural bleeding risk. While the haemostatic system of patients with compensated cirrhosis is often in a rebalanced haemostatic state due to a parallel decline in both pro- and anti-haemostatic factors, a decompensation of liver cirrhosis can lead to destabilization of this fragile equilibrium. Since conventional coagulation tests do not adequately capture the complex changes in the hemostatic system in cirrhosis, functional analysis methods such as viscoelastic tests or thrombin generation assays can be used for evaluating the coagulation status. This review describes the underlying pathophysiological changes in the hemostatic system in liver cirrhosis, provides an overview of diagnostic methods and discusses therapeutic measures in case of bleeding and thrombotic complications.
肝硬化患者的止血系统常表现出复杂改变,这可能与出血和血栓形成并发症相关。虽然应避免预防性纠正异常凝血参数,但在侵入性操作前建议采用个体化方法,在此过程中,稳定止血的具体预防措施应基于围手术期出血风险。虽然代偿期肝硬化患者的止血系统由于促凝血和抗凝血因子同时下降,常处于重新平衡的止血状态,但肝硬化失代偿可导致这种脆弱平衡的不稳定。由于传统凝血试验不能充分反映肝硬化患者止血系统的复杂变化,因此可使用粘弹性试验或凝血酶生成试验等功能分析方法来评估凝血状态。本综述描述了肝硬化患者止血系统潜在的病理生理变化,概述了诊断方法,并讨论了出血和血栓形成并发症的治疗措施。
