Abstract

A 68-year-old man with left cervical internal carotid artery stenosis suffered crescendo transient ischemic attacks caused by mobile thrombus detected by carotid echography and secondary impairment of cerebral hemodynamic reserve demonstrated by positron emission tomography. Urgent carotid endarterectomy (CEA) was performed following pretreatment with edaravone and early clamping of the carotid arteries without intraluminal shunting. The postoperative course was uneventful, and postoperative magnetic resonance imaging and single-photon emission computed tomography revealed no new cerebral ischemic lesions and no findings of cerebral hyperperfusion, respectively. The risks associated with CEA are higher for patients with evolving stroke or crescendo transient ischemic attacks than that for patients with stable disease. This case demonstrates that urgent endarterectomy for cervical carotid artery stenosis with crescendo transient ischemic attacks caused by mobile thrombi and hemodynamic cerebral ischemia can be successfully performed following pretreatment with edaravone and early clamping of the carotid arteries.
