Treatment of Idiopathic Recurrent Internal Carotid Artery Vasospasms with Bilateral Carotid Artery Stenting: A Case Report

抄録

Objective: Idiopathic recurrent internal carotid artery vasospasms refer to paroxysmal vasospasms of the internal carotid artery centering on the cervical segment, which are rare. We report a patient who underwent bilateral carotid artery stenting (CAS) for idiopathic recurrent internal carotid artery vasospasms.

Case Presentation: A 40-year-old male. Paroxysmal vasospasms of the internal carotid artery had occurred 5 or 6 times a month during the past 10 years, with headache, amaurosis fugax, hemiparesis, and aphasia. The attacks could not completely be reduced by drug therapy, and bilateral CAS was performed. The frequency of attacks decreased during a postoperative period of 6 months, and ischemic symptoms of the hemisphere had disappeared.

Conclusion: CAS for drug-resistant idiopathic recurrent internal carotid artery vasospasms may be useful for decreasing the frequency of attacks and preventing ischemic hemispheric symptoms.
