  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 ...

    70 percent stenosis of the right internal carotid artery as seen by ultrasound. Arrow marks the lumen of the artery. CT image of a 70 percent stenosis of the right internal carotid artery. Carotid artery stenosis is usually diagnosed by color flow duplex ultrasound scan of the carotid arteries in the neck.

    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.

    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]

    While this may be useful in detecting unknown carotid disease, it is not accurate enough to rule out disease. [1] It is estimated that 44% of patients who do not have a bruit on auscultation will still have significant stenosis of the carotid artery. [1] Carotid endarterectomy. This is a surgical procedure that is used to restore blood flow in ...

    In the neck, the artery issues branches to the digastric muscle, stylohyoid muscle, sternocleidomastoid muscle, and the parotid gland. [1]In the neck, the posterior auricular artery issues the stylomastoid artery which enters the stylomastoid foramen to provide arterial supply to the facial nerve (CN VII), tympanic cavity, mastoid air cells of the mastoid antrum, and the semicircular canals.

  8. Internal carotid artery - Wikipedia

    en.wikipedia.org/wiki/Internal_carotid_artery

    The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation. [ 1 ] In human anatomy, the internal and external carotid arise from the common carotid artery , where it bifurcates at cervical vertebrae C3 or C4.

  9. Common carotid artery - Wikipedia

    In at least one reported case, the artery was only 4 cm in length and divided at the root of the neck. Very rarely, the common carotid artery ascends in the neck without any subdivision, either the external or the internal carotid being absent; and in a few cases the common carotid has itself been found to be absent, the external and internal ...
