Alterations in normal coagulation and hemostasis are critical issues that require special attention in the neurosurgical patient. These disorders pose unique challenges in the management of these patients who often have concurrent acute ischemic and hemorrhagic injuries. Although neurosurgical intervention in such cases may be unavoidable and potentially life-saving, these patients should be closely observed after instrumentation.
A 57-year-old male with liver cirrhosis secondary to amyloid light-chain amyloidosis was admitted to the intensive care unit for the management of delayed hydrocephalus. An external ventricular drain (EVD) was placed for the treatment and monitoring of hydrocephalus. Five days after EVD placement, a head computed tomography scan revealed a tract hemorrhage. However, on repeated imaging, the size of the hemorrhage continued to increase despite aggressive blood pressure control and several doses of phytonadione. Extensive coagulopathy workup was remarkable for low factor VII levels. In that setting, recombinant activated factor VII was administered to normalize factor VII levels, and the tract hemorrhage stabilized.
To the best of our knowledge, this is the first case of spontaneous hemorrhage after EVD placement in the setting of liver cirrhosis-associated factor VII deficiency. Our case highlights the importance of identifying coagulation disorders in neurosurgical patients at high risk for coagulopathy and closely monitoring them postoperatively.
正常凝血和止血功能的改变是神经外科患者需要特别关注的关键问题。这些紊乱在管理这些常并发急性缺血性和出血性损伤的患者时带来了独特的挑战。尽管在这种情况下神经外科干预可能不可避免且可能挽救生命,但在进行器械操作后应密切观察这些患者。
一名57岁男性,继发于轻链淀粉样变的肝硬化,因延迟性脑积水入住重症监护病房。放置了一根脑室外引流管(EVD)用于治疗和监测脑积水。放置EVD五天后,头部计算机断层扫描显示引流道出血。然而,在重复成像时,尽管积极控制血压并多次给予维生素K1,出血的大小仍持续增加。广泛的凝血功能检查显示因子VII水平低。在这种情况下,给予重组活化因子VII以使因子VII水平正常化,引流道出血稳定下来。
据我们所知,这是第一例在肝硬化相关因子VII缺乏情况下放置EVD后发生自发性出血的病例。我们的病例强调了识别有凝血功能障碍高风险的神经外科患者的凝血紊乱并在术后密切监测他们的重要性。
