Late spontaneous recanalization of internal carotid artery is an unusual event that has received little attention. The authors report a case of a 73-year-old male patient, hypertensive, with previous history of cerebral vascular accident 3 years ago, with sensorimotor sequela in the right upper limb. Duplex scanning and arteriography showed total occlusion of the internal carotid artery. The patient progressed after 2 years with new episodes of recurrent transient ischemic attacks. When submitted to new imaging examinations to assess extra- and intracranial circulation, vessel recanalization was demonstrated, with severe stenosis. Left carotid endarterectomy was uneventfully performed. The patient progressed without new episodes after a 1-month follow-up. Considering the case rarity and the lack of literature on late carotid artery recanalization that can be surgically repaired, we decided to present this case focusing on the importance of following carotid artery occlusions.
Carotid artery stenosis; carotid artery stenosis; spontaneous remission; internal carotid artery; cerebral angiography; stroke
