Diagnostic ultrasound in stenting of the dissection in high position of extracranial internal carotid artery: case report

Abstract

Objective: We used transoral carotid ultrasonography (TOCU) and intravascular ultrasound (IVUS) to evaluate extracranial internal carotid artery dissection.
Case presentation: A 42-year-old woman presented with amaurosis fugax. Cerebral angiography demonstrated a stenotic lesion,4 cm in length, suggestive of dissection of the right internal carotid artery. TOCU and IVUS demonstrated an intimal flap floating in the lumen exhibiting pulsatile motion in its ulcerated portion. Self-expanding stent placement resulted in resolution of stenosis and pseudoaneurysm.
Conclusion: TOCU and IVUS are useful for stenting of internal carotid artery dissection.
