  • vertebrobasilar
  • There is controversy surrounding the risk of manipulation, which is often used by chiropractors, with respect to its association with vertebrobasilar artery system (VBA) stroke. (pushasrx.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)
  • 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)
  • The thrombus also extended into the proximal subclavian artery. (jcda.ca)
  • chiropractic
  • But an even more recent study points in the same direction to debunk the notion that chiropractic patients, as opposed to MD patients presenting with the same conditions in the neck and head, are more at risk for arterial dissection and stroke. (chiro.org)
  • 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)
  • patients
  • In most patients, the pathogenesis of arterial dissection is usually multifactorial. (medscape.com)
  • The advantages of MRI make this the preferred method for the initial screening and evaluation of patients with suspected arterial dissection. (medscape.com)
  • Years later, the proper control was finally provided with a massive patient database in Canada that clearly pointed out the risk of cervical arterial dissection was as great, if not greater, if patients with neck pain or headaches reported to a medical practitioner rather than a chiropractor. (chiro.org)
  • It should be noted, however, that the risk of arterial dissection in particular was not evaluated in this study, and that the severity of conditions among patients visiting a medical physician might have been greater prompting the increased likelihood of post-treatment injury in that group. (chiro.org)
  • Vertebral artery dissection (VAD) is a relatively rare but increasingly recognized cause of stroke in patients younger than 45 years. (medscape.com)
  • 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)
  • diabetes
  • The patient had no risk factors for an atherosclerotic vascular disease, e.g., hypertension, diabetes mellitus, coronary artery disease, dyslipidemia or smoking. (jcda.ca)
  • 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)
  • frequent
  • 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)
  • Patients
  • Objectives The authors sought to study the characteristics and outcomes of patients with contralateral carotid artery occlusions (CCOs) undergoing elective carotid artery stenting (CAS). (onlinejacc.org)
  • Methods In-hospital outcomes were examined in patients with and without CCO undergoing elective CAS in the Carotid Artery Revascularization and Endarterectomy (CARE) registry. (onlinejacc.org)
  • Emerging evidence from a high-risk patient population suggests that elective carotid artery stenting (CAS) is an acceptable treatment option for patients if performed by an experienced operator in a thoughtfully selected patient population ( 6 ). (onlinejacc.org)
  • In this study, we compared in-hospital outcomes between patients with and without CCOs undergoing elective CAS in the nationwide CARE (Carotid Artery Revascularization and Endarterectomy) registry. (onlinejacc.org)
  • From 1975 to 1993, 42 patients (mean age, 44 +/- 14 years) were admitted to the University Hospital of Angers for a carotid dissection studied first by ultrasonography, then defined by angiography. (biomedsearch.com)

  • This feeling is instead a intelligence to use our newly acquired biologic sensitivity of the dis- plenty to focus our trials on the pilfer patients and to choose the appropriate endpoints for the fine point trial. (hummercar.ru)
  • Cervicocephalic artery dissection chila_chap.Indd patients of lower extremity symptom begins with anatomy, fascia, biomechanics, respiration, lymphatics, and along the middle layer called mesenchyme at each visit. (river-centre.org)
  • veins
  • While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. (wikipedia.org)
