  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

    The carotid artery is the large vertical artery in red. The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy ...

  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. Atherosclerosis - Wikipedia

    en.wikipedia.org/wiki/Atherosclerosis

    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 ...

  6. Restenosis - Wikipedia

    en.wikipedia.org/wiki/Restenosis

    Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage, and subsequently become re-narrowed. This is usually restenosis of an artery, or other blood vessel, or possibly a vessel within an organ. Restenosis is a common adverse event of endovascular procedures.

  7. 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]

  8. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    The TOAST (Trial of Org 10172 in Acute Stroke Treatment) classification is based on clinical symptoms as well as results of further investigations; on this basis, a stroke is classified as being due to (1) thrombosis or embolism due to atherosclerosis of a large artery, (2) embolism of cardiac origin, (3) occlusion of a small blood vessel, (4 ...

  9. Cavernous sinus thrombosis - Wikipedia

    en.wikipedia.org/wiki/Cavernous_sinus_thrombosis

    Findings may include deformity of the internal carotid artery within the cavernous sinus, and an obvious signal hyperintensity within thrombosed vascular sinuses on all pulse sequences. Cerebral angiography can be performed, but it is invasive and not very sensitive. Orbital venography is difficult to perform, but it is excellent in diagnosing ...
