Changes in primary hemostasis have been described in patients with chronic liver disease (CLD) and cirrhosis and are still subject to ongoing debate. Thrombocytopenia is common and multifactorial. Numerous studies also reported platelet dysfunction. In spite of these changes, primary hemostasis seems to be balanced. Patients with CLD and cirrhosis can suffer from both hemorrhagic and thrombotic complications. Variceal bleeding is the major hemorrhagic complication and is mainly determined by high portal pressure. Non portal hypertension-related bleeding due to hemostatic failure is uncommon. Thrombocytopenia can complicate management of invasive procedures in CLD patients. Recently, oral thrombopoietin agonists have been approved to raise platelets before invasive procedures. In this review we aim to bundle literature, published over the past decade, discussing primary hemostasis in CLD and cirrhosis including (1) platelet count and the role of thrombopoietin (TPO) agonists, (2) platelet function tests and markers of platelet activation, (3) von Willebrand factor and (4) global hemostasis tests.
慢性肝脏疾病(CLD)和肝硬化患者的初级止血功能已发生变化,这仍然是一个有争议的话题。血小板减少症很常见且有多种病因。许多研究还报道了血小板功能障碍。尽管存在这些变化,但初级止血似乎是平衡的。CLD 和肝硬化患者既可能发生出血并发症,也可能发生血栓并发症。静脉曲张出血是主要的出血并发症,主要由高门静脉压力决定。非门静脉高压相关的止血功能障碍引起的出血并不常见。血小板减少症可能会使 CLD 患者的侵入性操作的管理复杂化。最近,口服促血小板生成素激动剂已被批准用于在侵入性操作前升高血小板。在这篇综述中,我们旨在汇集过去十年中发表的讨论 CLD 和肝硬化中初级止血的文献,包括(1)血小板计数和促血小板生成素(TPO)激动剂的作用,(2)血小板功能试验和血小板活化标志物,(3)血管性血友病因子和(4)整体止血试验。
