Familial association of intracranial aneurysms and cervical artery dissections.
BACKGROUND AND PURPOSE The familial occurrence of intracranial aneurysms and cervical artery dissections has been described in different families and supports the hypothesis that a primary arteriopathy may play a role in the pathogenesis of these disorders. Although the basis for this arteriopathy is generally not believed to be similar among cases of intracranial aneurysms and cervical artery ...
متن کاملSpontaneous cervical artery dissection: from risk factors toward pathogenesis.
The pathogenesis of a cervical artery dissection (CAD) remains unknown in most cases.1,2 Dissections are usually classified as either traumatic or spontaneous.3 However, mechanical trauma did not appear to be an important and frequent cause for the development of CAD, neither in clinical nor in histopathological studies. Chiropractic maneuver, for instance, was repeatedly discussed as a risk fa...
متن کاملSpontaneous Cervical Artery Dissection: The Borgess Classification
BACKGROUND AND PURPOSE The pathogenesis of spontaneous cervical artery dissections (sCAD) and its best medical treatment are debated. This may be due to a lack of clear classification of sCAD. We propose the new Borgess classification of sCAD, based on the presence or absence of intimal tear as depicted on imaging studies and effect on blood flow. MATERIALS AND METHODS This is a single-center...

متن کاملHeadaches in cervical artery dissections.
Internal carotid artery (ICA) and vertebral artery (VA) dissections are among the common causes of stroke in middle-aged and young adults. The spectrum of clinical presentations of these dissections is broad. Many patients, especially those with ICA dissections, may never develop a stroke.
متن کاملJuvenile Stroke: Cervical Artery Dissection in a Patient after a Polytrauma
Dissections of the cervical arteries cause about 20% of total juvenile strokes. Approximately 4% of the carotid artery dissections are due to a (poly)trauma such as car accidents. Despite improved diagnostic facilities, traumatic dissections are often underdiagnosed or diagnosed too late due to a lack of awareness of potential initial signs and symptoms. We report here a case of a delayed embol...
