A Case of Stent-assisted Coil Embolization for Aneurysmal Dilation after Extracranial Internal Carotid Artery Dissection

Abstract

  In this report, we described a case of idiopathic extracranial right internal carotid artery dissection, which was followed by coil embolization with stenting of the aneurysm at the same site 2 years later. A 44-year-old man presented to our outpatient clinic with a chief complaint of right neck pain. He was diagnosed with idiopathic extracranial internal carotid artery dissection. Two years later, an asymptomatic aneurysm was detected in the dissected area, and stent-assisted coil embolization was performed. Few studies have reported aneurysms forming several years following arterial dissection remission. Long-term follow-up is necessary because aneurysm formation may be associated with a chronic course.
