Internal carotid artery dissection

Abstract

The purpose of this review is to increase the awareness of internal carotid artery dissection (ICAD), a potentially serious and probably underdiagnosed condition. ICAD is a not uncommon cause of stroke in young patients. ICAD may occur spontaneously or as a result of trauma. However, the "spontaneous" dissection is often preceded by a trivial trauma. The typical patient presents with ipsilateral headache or neck pain, ipsilateral Horner's syndrome and delayed ischemic symptoms from the ipsilateral hemisphere or retina. Conventional angiography, the gold standard for diagnosis, tends to be replaced by non-invasive diagnostic methods. There are no evidence-based guidelines for therapy although anticoagulation is most commonly used. The references are selected from the Medline database for the years 1966-1997.
