Background Large fat embolus is a rare but potential reversible cause of ischaemic stroke. Methods and results We describe the neurosurgical management of a complete right internal carotid artery occlusion due to a large fat embolus, caused by a mitral valve replacement. Conclusion Knowledge of acute cerebral ischaemia due to large fat embolism and its hallmark ‘hypodense artery’ is mandatory. Extracranial to intracranial bypass is a feasible rescue treatment after failure of endovascular embolectomy.

当脂肪击中大脑时——挽救 STA-MCA 旁路，治疗因脂肪栓塞导致的颅内 ICA 闭塞


背景 大脂肪栓塞是缺血性中风的一种罕见但潜在可逆的原因。方法和结果 我们描述了因二尖瓣置换术引起的大脂肪栓塞导致的右颈内动脉完全闭塞的神经外科治疗。结论 大脂肪栓塞引起的急性脑缺血及其标志性“低密度动脉”的知识是强制性的。颅外至颅内转流术是血管内取栓失败后可行的抢救治疗方法。
