Common carotid artery occlusion is rare. Bilateral common carotid artery occlusion is extremely rare and, to our knowledge, has hardly ever been reported. This report describes a case of fatal stroke with acute simultaneous bilateral common carotid artery occlusion presenting as sudden coma. A 90-year-old woman was transferred to our hospital by ambulance with a sudden coma. She had a history of atrial fibrillation but had not taken any oral antithrombotic medication in recent years. She had been receiving house calls for dehydration in the previous week. Magnetic resonance imaging showed extensive cerebral infarcts in both cerebral hemispheres, and magnetic resonance angiography revealed bilateral common carotid artery occlusion. Acute recanalization therapy was not performed because of the extensive cerebral infarction, the patient's advanced age, and her poor ability to perform activities of daily living. On the day after onset, she died of massive cerebral infarction and marked brain swelling.
