Carotid triangle Carotid triangle The carotid triangle (or superior carotid triangle) is a portion of the anterior triangle of the neck. It is bounded: It is (covered) by the integument, superficial fascia, Platysma and deep fascia; Its floor is formed by parts of the -1 Thyrohyoid membrane, -2Hyoglossus, and the -3Constrictores pharyngis medius and inferior. The external and internal carotids lie side by side, the external being the more anterior of the two. The following branches of the external carotid are also met with in this space: The veins met with are: ...all of which end in the internal jugular vein Superficial
Intima-media thickness not satisfactory. IMT can be measured using external ultrasound in large arteries relatively close to the skin (e.g. the carotid, brachial, radial, or femoral arteries). External ultrasound methods have the advantage of being non-invasive, comparatively low cost and convenient. Deeper internal arteries, such as the coronary arteries require special intravascular catheters employing ultrasound or optical coherence tomography to measure IMT. The carotid artery is the usual site of measurement of IMT and consensus statements for carotid IMT have been published for adults and children. Often, IMT is measured in three locations: in the common carotid artery (typically at one cm
