A woman with carotid atherosclerotic plaques suffered a massive cerebral infarction after carbon monoxide poisoning-A case report.

Cases of carbon monoxide (CO) poisoning complicated with massive cerebral infarction are rare. A chinese female patient with carotid atherosclerotic plaque was found unconscious during bathing. The patient was diagnosed as carbon monoxide poisoning complicated with massive acute cerebral infarction by carbon monoxide hemoglobin (COHb) detection and imaging examination. The patient regained consciousness after treatment with hyperbaric oxygen, antiplatelet, and atorvastatin. This case suggests that patients with carotid atherosclerotic plaque may be more susceptible to develop acute cerebral infarction when CO poisoning occurs.
