Hemiplegia after carbon monoxide (CO) poisoning is rare since only 9 such lesions have been reported from among 1480 cases of poisoning. The patient reported was a 43 year-old man with a left hemiplegia with coma following CO poisoning. Right carotid angiography demonstrated a hypoglossal artery supplying both posterior cerebral arteries. Left carotid angiography showed a dolichocarotid artery supplying the territories of the anterior and middle cerebral arteries on both sides. Complete regression of the hemiplegia occurred after 2 months following rapid administration of hyperbaric oxygen. Normal CT scan images and cerebral blood flow rates on follow-up examination suggest that the left hemiplegia was due to the combined effects of arterial anomalies and CO poisoning.
一氧化碳（CO）中毒后偏瘫较为罕见，因为在1480例中毒病例中仅报告了9例此类病变。报告的患者是一名43岁男性，一氧化碳中毒后出现左侧偏瘫并昏迷。右侧颈动脉血管造影显示舌下动脉供应双侧大脑后动脉。左侧颈动脉血管造影显示一条长颈动脉供应双侧大脑前动脉和大脑中动脉的区域。在快速给予高压氧治疗2个月后，偏瘫完全消退。随访检查时正常的CT扫描图像和脑血流速度表明，左侧偏瘫是动脉异常和一氧化碳中毒共同作用的结果。
