  2. Carotid ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Carotid_ultrasonography

    Carotid ultrasonography is an ultrasound-based diagnostic imaging technique to evaluate structural details of the carotid arteries. Carotid ultrasound is used to diagnose carotid artery stenosis (CAS) and can assess atherosclerotic plaque morphology and characteristics. [1] Carotid duplex and contrast-enhanced ultrasound are two of the most ...

  3. 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]

  4. Intima–media thickness - Wikipedia

    en.wikipedia.org/wiki/Intima–media_thickness

    The carotid artery is the usual site of measurement of IMT and consensus statements for carotid IMT have been published for adults [12] and children. [13] Often, carotid IMT is measured in three locations: in the common carotid artery (typically at one cm proximal to the flow divider), at the bifurcation, and in the internal carotid artery.

  5. Vascular surgery - Wikipedia

    en.wikipedia.org/wiki/Vascular_surgery

    Carotid artery stenosis is caused by atherosclerosis whereby the buildup of atheromatous plaque inside the artery causes narrowing. Symptoms of carotid artery stenosis can include transient ischemic attack or stroke. Both symptomatic and asymptomatic carotid stenosis can be diagnosed with the aid of carotid duplex ultrasound which allows for ...

  6. Peripheral artery disease - Wikipedia

    en.wikipedia.org/wiki/Peripheral_artery_disease

    Testing for coronary artery disease or carotid artery disease is of unclear benefit. [20] While PAD is a risk factor for abdominal aortic aneurysms (AAA), there is no data on screening individuals with asymptomatic PAD for abdominal aortic aneurysms. [20] For people with symptomatic PAD, screening by ultrasound for AAA is not unreasonable. [20]

  7. 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 ]

  8. 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 ...

  9. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    The machine used is called an ultrasound machine, a sonograph or an echograph. The visual image formed using this technique is called an ultrasonogram, a sonogram or an echogram. Ultrasound of carotid artery. Ultrasound is composed of sound waves with frequencies greater than 20,000 Hz, which is the approximate upper threshold of human hearing. [1]
