Analysis of the relationship between the double transverse foramen and the possibility of developing clinical symptoms after whiplash
2017
Introduction: Currently there is no information about the possibility of developing clinical symptoms after whiplash in double transverse foramen subjects. Our aim was to test whether subjects with double transverse foramen have an increased risk of presenting with acute headache, dizziness, vertebral artery dissection, and vomiting after whiplash. Methods: We recorded the absence/presence of double transverse foramen, and the absence/presence of neck pain, acute headache, dizziness, vertebral artery dissection, and vomiting in 85 patients who had suffered whiplash injuries in car rear-end impacts in road traffic accidents. We used the odds ratio test to determine whether double transverse …
The Decreasing Prevalence of the Arcuate Foramen
2018
[Background]: The arcuate foramen (AF), or ponticulus posticus, is an anatomic variant of the first cervical vertebra that consists of a complete or partial osseous bridge over the groove for the vertebral artery and extends from the posterior aspect of the superior articular facet to the superior lateral border of the posterior arch. The AF has been associated with clinical symptoms, such as headache, migraine, neck pain, shoulder pain, arm pain, and vertebral artery dissection. We aimed to test whether the prevalence of the AF has decreased in the modern human population over the past centuries as a result of reduction in inbreeding and endogamy.
Bilateral vertebral artery dissection, agenesis of both ICAs, and connective tissue aberrations
2013
A 35-year-old woman presented with acute signs of stroke (appendix e-1 on the Neurology® Web site at [www.neurology.org][1]). After initial CT with angiography, MRI with time-of-flight angiography confirmed agenesis of both internal carotid arteries (ICAs; figure 1A). It revealed bilateral vertebral artery (VA) dissections and ischemias in both middle artery territories (figure 1, A–E). Skin biopsy microscopy (figure 2) was consistent with ultrastructural connective tissue disease (uCTD), for which no further evidence was found apart from mild hypermobility of the finger joints. The underlying uCTD with structural instability of the arterial walls and the increased blood flow in the vertebr…
Incidence and outcome of cerebrovascular events related to cervical artery dissection: the Dijon Stroke Registry.
2013
Background Reliable epidemiological data on the true incidence of cerebrovascular events related to spontaneous cervical artery dissection, including stroke and transient ischemic attack, are scarce. Aims To evaluate the incidence, characteristics, and outcome of cerebrovascular events due to cervical artery dissection. Methods All cerebrovascular events (stroke and transient ischemic attack) occurring in Dijon, France, from 2006 to 2011, were retrieved from a population-based registry. Patients with a cervical artery dissection were identified. Incidence rates, baseline characteristics, and outcome at three-months were described. Results Among the 1368 patients with cerebrovascular events,…
Common variation in PHACTR1 is associated with susceptibility to cervical artery dissection
2014
Item does not contain fulltext Cervical artery dissection (CeAD), a mural hematoma in a carotid or vertebral artery, is a major cause of ischemic stroke in young adults although relatively uncommon in the general population (incidence of 2.6/100,000 per year). Minor cervical traumas, infection, migraine and hypertension are putative risk factors, and inverse associations with obesity and hypercholesterolemia are described. No confirmed genetic susceptibility factors have been identified using candidate gene approaches. We performed genome-wide association studies (GWAS) in 1,393 CeAD cases and 14,416 controls. The rs9349379[G] allele (PHACTR1) was associated with lower CeAD risk (odds ratio…
