This is the first case of transient basilar occlusive disease diagnosed and monitored by transcranial Doppler. This case is important and needs to be reported because transient basilar occlusion may be easily diagnosed if transcranial Doppler is performed. Case presentation A 79-year-old woman affected by chronic atrial fibrillation and not treated with oral anticoagulants cardioverted to sinus rhythm during a gastric endoscopy. She then showed a sudden-onset loss of consciousness horizontal and vertical gaze palsy tetraparesis and bilateral miosis and coma. Two hours later the symptoms resolved quickly leaving no residual neurologic deficits. Transcranial Doppler examination showed a dampened flow in the basilar artery in the emergency examination and a restored flow when the symptoms resolved. Conclusion This is the first case of transient basilar occlusive disease diagnosed and monitored by transcranial Doppler. We believe that transcranial Doppler should be performed in all cases of unexplained acute loss of consciousness in particular if associated with signs of brainstem dysfunctions. Introduction Embolic occlusion of the basilar artery has been described as a dramatic event with a severe and even fatal outcome if occlusion is permanent and with a more benign course if the occlusion is transient 1 . .
