Spontaneous intracerebral hemorrhage (ICH) is a medical emergency and is disproportionately associated with higher mortality and long-term disability compared with ischemic stroke. The phrase "time is brain" was derived for patients with large vessel occlusion ischemic stroke in which approximately 1.9 million neurons are lost every minute. Similarly, this statement holds true for ICH patients due to a high volume of neurons that are damaged at initial onset and during hematoma expansion. Most cases of spontaneous ICH pathophysiologically stem from chronic hypertension and rupture of small perforating vessels off of larger cerebral arteries supplying deep brain structures, with cerebral amyloid angiopathy being another cause for lobar hemorrhages in older patients. Optimal ICH medical management strategies include timely diagnosis, aggressive blood pressure control, correction of underlying coagulopathy defects if present, treatment of cerebral edema, and continuous assessment for possible surgical intervention. Current strategies in the surgical management of ICH include newly developed minimally invasive techniques for hematoma evacuation, with the goal of mitigating injury to fiber tracts while accessing the clot. We review evidence-based medical and surgical management of spontaneous ICH with the overall goal of reducing neurologic injury and optimizing functional outcome.
自发性脑出血(ICH)是一种医疗急症,与缺血性脑卒中相比,其死亡率和长期残疾率更高。“时间就是大脑”这句话适用于大血管闭塞性缺血性脑卒中患者,因为每过一分钟就会有大约 190 万个神经元死亡。同样,由于大量神经元在初始发病时和血肿扩大过程中受损,这句话也适用于 ICH 患者。大多数自发性 ICH 的病理生理学源于慢性高血压和大脑动脉深部结构供应的较小穿透性血管破裂,而脑淀粉样血管病是老年患者发生脑叶出血的另一个原因。ICH 的最佳医疗管理策略包括及时诊断、积极控制血压、纠正潜在的凝血功能障碍缺陷、治疗脑水肿以及持续评估是否需要手术干预。ICH 手术治疗的当前策略包括新开发的血肿清除微创技术,其目标是在清除血栓的同时减轻纤维束的损伤。我们回顾了自发性 ICH 的循证医学和手术管理,总体目标是减轻神经损伤并优化功能结果。
