Abstract
Background:
Carotid webs are luminal, shelf-like protrusions at the carotid bulb. Considered to be a variant of fibromuscular dysplasia, carotid webs have been observed principally in African American females. The association between carotid webs and recurrent ischemic strokes continues to be established as patients without traditional stroke risk factors are found to have carotid webs as the only possible cause of symptomatic deficits. The majority of patients undergo endarterectomy; few stent placements are reported. We present the case of an African American female who underwent stent placement for treatment and secondary prevention of stroke attributed to a carotid web.
Case Report:
A 33-year-old African American female presented with acute onset left hemiparesis and left facial droop. Alteplase was administered; multiphase head and neck computed tomography angiography revealed an occlusion of the right middle cerebral artery with a web at the carotid bulb. Aspiration catheter thrombectomy achieved a Thrombolysis in Cerebral Infarction (TICI) score of 3. She was placed on 2 antiplatelet agents, and 3 weeks later she underwent stent placement. Follow-up digital subtraction angiography at 3 months showed obliteration of the right carotid artery web and satisfactory integration of the stent into the vessel wall. She was reassessed at 1 year and reported no neurologic symptoms.
Conclusion:
Although carotid webs are most commonly treated with endarterectomy, they may be amenable to stent therapy with favorable clinical outcomes as shown with this patient.
