Patients receiving anticoagulation therapy who present with any type of intracranial hemorrhage--including subdural hematoma, epidural hematoma, subarachnoid hemorrhage, and intracerebral hemorrhage (ICH)--require urgent correction of their coagulopathy to prevent hemorrhage expansion, limit tissue damage, and facilitate surgical intervention as necessary. The focus of this review is acute ICH, but the principles of management for anticoagulation-associated ICH (AAICH) apply to patients with all types of intracranial hemorrhage, whether acute or chronic. A number of therapies--including fresh frozen plasma (FFP), intravenous vitamin K, activated and inactivated prothrombin complex concentrates (PCCs), and recombinant activated factor VII (rFVIIa)--have been used alone or in combination to treat AAICH to reverse anticoagulation, help achieve hemodynamic stability, limit hematoma expansion, and prepare the patient for possible surgical intervention. However, there is a paucity of high-quality data to direct such therapy. The use of 3-factor PCC (activated and inactivated) and rFVIIa to treat AAICH constitutes off-label use of these therapies in the United States. However, in April 2013, the US Food and Drug Administration (FDA) approved Kcentra (a 4-factor PCC) for the urgent reversal of vitamin K antagonist (VKA) anticoagulation in adults with acute major bleeding. Plasma is the only other product approved for this use in the United States. (1) Inconsistent recommendations, significant barriers (e.g., clinician-, therapy-, or logistics-based barriers), and a lack of approved treatment pathways in some institutions can be potential impediments to timely and evidence-based management of AAICH with available therapies. Patient assessment, therapy selection, whether to use a reversal or factor repletion agent alone or in combination with other agents, determination of site-of-care management, eligibility for neurosurgery, and potential hematoma evacuation are the responsibilities of the neurosurgeon, but ultimate success requires a multidisciplinary approach with consultation from the emergency department (ED) physician, pharmacist, hematologist, intensivist, neurologist, and, in some cases, the trauma surgeon.
正在接受抗凝治疗的患者出现任何类型的颅内出血——包括硬膜下血肿、硬膜外血肿、蛛网膜下腔出血和脑出血 (ICH)——需要紧急纠正其凝血功能障碍,以防止出血扩大、限制组织损伤,并在必要时便于手术干预。本综述的重点是急性 ICH,但抗凝相关 ICH (AAICH) 的治疗原则适用于所有类型的颅内出血患者,无论是急性还是慢性。许多治疗方法——包括新鲜冷冻血浆 (FFP)、静脉维生素 K、活化和失活的凝血酶原复合物浓缩物 (PCC) 和重组活化因子 VII (rFVIIa)——已单独或联合用于治疗 AAICH 以逆转抗凝、帮助实现血流动力学稳定、限制血肿扩大并为可能的手术干预做好准备。然而,缺乏高质量的数据来指导这种治疗。使用 3 因子 PCC(活化和失活)和 rFVIIa 治疗 AAICH 构成了这些疗法在美国的标签外使用。然而,2013 年 4 月,美国食品和药物管理局 (FDA) 批准 Kcentra(一种 4 因子 PCC)用于紧急逆转成人急性大出血的维生素 K 拮抗剂 (VKA) 抗凝。在美国,只有其他一种血浆产品被批准用于这种用途。(1)不一致的建议、重大障碍(例如,临床医生、治疗、或后勤障碍)以及一些机构缺乏批准的治疗途径,可能会对 AAICH 的及时和基于证据的管理以及可用疗法的使用造成潜在的阻碍。患者评估、治疗选择、是否单独使用逆转或因子补充剂或与其他药物联合使用、确定治疗地点管理、是否有资格接受神经外科手术以及潜在的血肿清除是神经外科医生的责任,但最终成功需要多学科方法,咨询急诊科 (ED) 医生、药剂师、血液科医生、重症监护医生、神经科医生,在某些情况下,还需要咨询创伤外科医生。
