Cerebral air embolism is a known complication from a myriad of iatrogenic causes. This case describes a 60-year-old female presenting from hemodialysis with altered mental status, bilateral homonymous hemianopia, and repetitive speech. A noncontrast head CT revealed air in the vein of Galen and the deep cerebral veins of the left thalamus and occipital sulcus, a complication from air being introduced into the patient via improper flushing of dialysis tubing. The retrograde flow of air bubbles in the upright patient during dialysis was likely responsible for the air embolus lodging in the cerebral vasculature. This patient was transferred to receive hyperbaric therapy, whereupon the patient survived with residual attention and spatial deficits.
脑空气栓塞是一种由多种医源性原因导致的已知并发症。该病例描述了一名60岁女性，因血液透析出现精神状态改变、双侧同向性偏盲和言语重复。头部非增强CT显示大脑大静脉、左侧丘脑和枕沟的大脑深静脉中有空气，这是由于透析管路冲洗不当导致空气进入患者体内引起的并发症。透析过程中直立患者体内气泡的逆流可能是空气栓子滞留在脑血管系统的原因。该患者被转至高压氧治疗，最终存活下来，但仍存在注意力和空间感知方面的残留缺陷。
