动脉瘤性蛛网膜下腔出血是一种发病率和病死率都较高的疾病。迟发性脑缺血(DCI)是导致患者高病死率的主要原因。DCI的发病机制涉及脑血管痉挛、皮层扩散抑制、微血栓形成、微循环功能障碍等。治疗方法包括循环动力治疗、血管内治疗、尼莫地平、他汀类药物、硫酸镁及其他药物治疗。现主要从发病机制及治疗方法等方面对DCI予以综述。 Aneurysmal subarachnoid hemorrhage is a disease with a high morbidity and mortality. Delayed cerebral ischemia (DCI) is the leading cause of high patient mortality. The pathogenesis of DCI involves cerebral vasospasm, inhibition of cortical spread, microthrombus formation, microcirculation dysfunction, and the like. Treatments include revascularization, endovascular therapy, nimodipine, statins, magnesium sulfate and other medications. Now mainly from the pathogenesis and treatment of DCI to be reviewed.
