All patients had undergone Doppler sonography of the carotid and/or vertebral arteries
3) Although spontaneous dissection can occur in arteries throughout the body, the extracranial segments of the carotid and vertebral arteries
are particularly vulnerable because of their greater mobility and proximity to the skin and to bony structures such as the cervical vertebrae and the styloid process.
Blood supply to the spinal cord is provided by one ASA and two posterior spinal arteries, all three of which originate from the vertebral arteries
Thus far, case reports in the medical literature have described arterial PICC placement with the catheter tip central to the carotid or vertebral arteries
A retrospective review of patients who had undergone CTA of the vertebral arteries
It is designed for mechanical blood clot removal in the neurovasculature, including the internal carotid artery, M1 and M2 segments of the middle cerebral artery, and the basilar and vertebral arteries
Futher de Kok-Mercado and neuroradiologist Philippe Gailloud, study senior investigator and interventional, found small vessel connections between the carotid and vertebral arteries
- not usually seen in adult humans - that allow blood to be exchanged between the two blood vessels.
Owls also turn out to have little connections 6 dubbed "anastomoses" -- between their carotid and vertebral arteries
that allow the two vessels to exchange blood.
Both common carotid arteries and both vertebral arteries
occlusion (four-vessel occlusion, 4-V0) induced severe cognitive deficits tested by water maze task, along with oxidative stress in hippocampus.
Vascular bed involvement among the first registry patients included one or both renal arteries in 69%, at least one extracranial carotid in 62%, vertebral arteries
in 19%, and mesenteric arteries in 12%.
Different types of mechanical "trauma" may compromise the vertebral arteries
or internal carotid arteries causing a cerebrovascular accident (CVA) including: sporting activities, activities of daily living, major trauma such as a road traffic accidents, a minor fall, sneezing, turning the head while backing a car, fair rides and CSM (Di Fabio 1999, Haldeman et al 2002, Kawchuk et al 2008).
Due to her neurologic symptoms a magnetic resonance angiogram was ordered revealing 90% stenosis of her bilateral carotid and vertebral arteries
