• stenosis
  • Note that the artery is not completely occluded and a thin continuous string of contrast is present along the length of the stenosis. (medscape.com)
  • hematoma
  • Mural hematoma usually is located within the media or the subintimal layer, leading to a "pseudo" enlargement of the artery (2) . (ajnr.org)
  • ie, a narrowed eccentric signal void (arterial lumen), a surrounding semi-lunar high signal (mural hematoma), and an increased diameter of the artery (6, 16, 17) . (ajnr.org)
  • intracranial
  • We also excluded studies on purely intracranial dissections, a different phenotype than CAD, although both may have some predisposing risk factors in common. (ahajournals.org)
  • High-resolution magnetic resonance imaging (HR-MRI) is the most important and popular vessel wall imaging technique for directly evaluating the vascular wall and intracranial artery disease. (j-stroke.org)
  • Intracranial artery atherosclerosis, dissection, moyamoya disease, vasculitis, and reversible cerebral vasoconstriction syndrome can also be diagnosed and differentiated by using HR-MRI. (j-stroke.org)
  • Although this evaluation is still one of the most important methods for assessing intracranial and carotid artery disease, it is limited in comparison with advanced imaging techniques. (j-stroke.org)
  • When assessing intracranial artery disease, HR-MRI is one of the most important and popular vessel wall imaging techniques for directly evaluating the vascular wall. (j-stroke.org)
  • thrombus
  • If no thrombus is observed in either the true lumen or the false lumen, the tearing membrane appears floating within the lumen, and the dissection is defined as a double-lumen dissection, which is not as prevalent as the other types of dissection. (medscape.com)
  • coronary
  • The patient had no risk factors for an atherosclerotic vascular disease, e.g., hypertension, diabetes mellitus, coronary artery disease, dyslipidemia or smoking. (jcda.ca)
  • Arrhythmic sudden cardiac death in a 3-year-old child with intimal fibroplasia of coronary arteries, aorta, and its branches. (medscape.com)
  • subintimal
  • Dissection is usually accompanied by hemorrhage into the arterial wall, which creates, as demonstrated in the first image below, a blind pouch or (uncommonly) a parallel subintimal second channel. (medscape.com)
  • anatomic
  • The evaluation of VA dissection by using noninvasive techniques remains difficult because of the small size of VAs, their deep location, frequent anatomic variations, and surrounding structures (11−15). (ajnr.org)
  • Traumatic
  • Traumatic dissection is the result of either external mechanical injury, such as a penetrating or blunt trauma, or trivial trauma that is related to a movement or abrupt change in head position. (medscape.com)
  • Disabled and primarily bedridden after traumatic brain injury and diabetes insipidus (TBI with DI), dysautonomia, gastroparesis, and vertebral artery dissection, Margaret continues to her social media expertise to validate and encourage the sick and oppressed, especially the RebelPatient. (saysagainspirational.com)
  • neurologic
  • 1 ⇓ - 3 Golf-related injuries are caused by either overuse or mechanical trauma, with most neurologic injuries being confined to the vertebral column. (ajnr.org)
  • METHODS
  • The ultrasonic methods (continuous wave Doppler combined with color Doppler flow imaging) failed only when they are performed late and when moderate or segmental intrapetrosal dissections were present. (biomedsearch.com)
  • branches
  • Moreover, as aorta branches into smaller arteries, their elasticity goes on decreasing and their compliance goes on increasing. (wikipedia.org)
