We describe a 47-year-old female patient with a carotid web and ischemic stroke. A carotid web is a membrane-like shelf of tissue, predominantly affecting the intimal layer of the arterial wall, usually extending from the posterolateral wall of the carotid artery into the lumen, typically at the origin of the internal carotid artery just beyond the bifurcation. It is considered to be an under-recognized etiology of ischemic stroke in young and middle-aged patients. Typically, these patients do not show any coexistent or only few vascular risk factors. Digital subtraction angiography, computer tomography angiography, magnetic resonance angiography, and color-coded duplex sonography are able to identify carotid webs. Therapy strategies include conservative therapy with intake of antiplatelet agents and anticoagulants, or carotid endarterectomy or carotid artery stenting. Optimal therapy strategy remains open. A considerable rate of recurrent cerebrovascular ischemic events has been reported in patients with a symptomatic carotid web and conservative therapy. More data are needed on prevalence, diagnosis, prognosis and therapy of patients with an asymptomatic or a symptomatic carotid web.
