Risk factors, radiological features, and infarct topography of craniocervical arterial dissection

Abstract

BACKGROUND: Craniocervical arterial dissection is a common cause of ischemic stroke in the young to middle-aged population. There have been a number of previous studies where radiological features have been described but few with detailed mapping of infarct topography and none where these features have been related to the reported risk factors. AIMS: The aims of this study were to describe the radiological characteristics of dissection patients ≤55 years and relate these to reported risk factors. METHODS: Craniocervical arterial dissection cases ≤55 years, and age- and gender-matched controls were identified from a medical records database between 1998 and 2009. Control cases had stroke from..
