  2. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

  3. Carotid endarterectomy - Wikipedia

    en.wikipedia.org/wiki/Carotid_endarterectomy

    Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.

  4. Arterial occlusion - Wikipedia

    en.wikipedia.org/wiki/Arterial_occlusion

    Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]

  5. Restenosis - Wikipedia

    An occlusion, or the blocking of all blood flow through a vessel, is considered 100% percent diameter stenosis. ... or the carotid artery in the neck). ...

    Doppler ultrasound of right internal carotid artery with calcified and non-calcified plaques showing less than 70% stenosis Lumen stenosis that is greater than 75% was considered the hallmark of clinically significant disease in the past because recurring episodes of angina and abnormalities in stress tests are only detectable at that ...

  7. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    Carotid endarterectomy is also indicated to decrease the risk of cerebral infarction for symptomatic carotid stenosis (>70 to 80% reduction in diameter). [ 38 ] In tissue losses that are not immediately fatal, the best course of action is to make every effort to restore impairments through physical therapy , cognitive therapy , occupational ...

  8. T2*-weighted imaging - Wikipedia

    en.wikipedia.org/wiki/T2*-weighted_imaging

    The T 2 *-weighted GRE sequence can detect a "middle cerebral artery susceptibility sign", which is a dark linear filling defect that is wider than the corresponding artery on the contralateral side. This sign is 83% sensitive and 100% specific for thrombotic occlusion of the internal carotid artery. [2]

  9. Thromboangiitis obliterans - Wikipedia

    en.wikipedia.org/wiki/Thromboangiitis_obliterans

    Thromboangiitis obliterans, also known as Buerger disease (English / ˈ b ɜːr ɡ ər /; German: [ˈbʏʁɡɐ]) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet.
