Spontaneous intracerebral hemorrhage (ICH), defined as nontraumatic bleeding into the brain parenchyma, is the second most common subtype of stroke, with 5.3 million cases and over 3 million deaths reported worldwide in 2010. Case fatality is extremely high (reaching approximately 60 % at 1 year post event). Only 20 % of patients who survive are independent within 6 months. Factors such as chronic hypertension, cerebral amyloid angiopathy, and anticoagulation are commonly associated with ICH. Chronic arterial hypertension represents the major risk factor for bleeding. The incidence of hypertension-related ICH is decreasing in some regions due to improvements in the treatment of chronic hypertension. Anticoagulant-related ICH (vitamin K antagonists and the newer oral anticoagulant drugs) represents an increasing cause of ICH, currently accounting for more than 15 % of all cases. Although questions regarding the optimal medical and surgical management of ICH still remain, recent clinical trials examining hemostatic therapy, blood pressure control, and hematoma evacuation have advanced our understanding of ICH management. Timely and aggressive management in the acute phase may mitigate secondary brain injury. The initial management should include: initial medical stabilization; rapid, accurate neuroimaging to establish the diagnosis and elucidate an etiology; standardized neurologic assessment to determine baseline severity; prevention of hematoma expansion (blood pressure management and reversal of coagulopathy); consideration of early surgical intervention; and prevention of secondary brain injury. This review aims to provide a clinical approach for the practicing clinician.
自发性脑出血(ICH)定义为脑实质内的非创伤性出血,是中风的第二常见亚型,2010年全球报告有530万例病例和超过300万例死亡。病死率极高(事件发生后1年时达到约60%)。存活患者中只有20%在6个月内能够独立生活。慢性高血压、脑淀粉样血管病和抗凝等因素通常与ICH相关。慢性动脉高血压是出血的主要危险因素。由于慢性高血压治疗的改善,某些地区高血压相关ICH的发病率正在下降。抗凝相关ICH(维生素K拮抗剂和新型口服抗凝药物)是ICH越来越常见的病因,目前占所有病例的15%以上。尽管关于ICH的最佳药物和手术治疗仍存在问题,但最近关于止血治疗、血压控制和血肿清除的临床试验增进了我们对ICH治疗的理解。急性期及时、积极的治疗可能减轻继发性脑损伤。初始治疗应包括:初始医疗稳定;快速、准确的神经影像学检查以确立诊断并阐明病因;标准化的神经学评估以确定基线严重程度;预防血肿扩大(血压管理和凝血障碍的逆转);考虑早期手术干预;以及预防继发性脑损伤。本综述旨在为临床医生提供一种临床方法。
