| carotid artery | <anatomy, artery> A key artery located in the front of the neck that carries blood from the heart to the brain. Cholesterol plaques on the inner wall of the carotid artery can lead to stroke. (12 Dec 1998) |
|---|---|
| carotid artery bruit | <radiology> Differential diagnosis: Atherosclerotic plaque or stenosis in common carotid artery or major vessels., Normal vessel. Asymptomatic bruits are a risk factor for stroke, and 75% of strokes occur in the carotid circulation. The majority of patients with bruits will have stenosis of 50% or more. The vast majority (90%) of strokes occur without prior symptoms. REF: MacNeil BJ, Abrams HL. Brigham and Women's Hospital Handbook of Diagnostic Imaging. Chapter 27. (12 Dec 1998) |
| carotid artery, common | The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries. (12 Dec 1998) |
| carotid artery, external | Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck. (12 Dec 1998) |
| carotid artery, internal | Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose. (12 Dec 1998) |
| vertebral artery | <anatomy, artery> Paired arteries which supply the muscles of the neck, spinal cord and cerebellum. (27 Sep 1997) |
| carotid artery occlusive syndrome | <syndrome> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome. Characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |

| carotid artery thrombosis | Formation of a clot in a carotid artery often resulting from atherosclerosis. Patients are at high risk for developing stroke. (12 Dec 1998) |
| carotid-vertebral artery anastomoses | <radiology> Trigeminal a. (most common variant: 0.1-0.2%), otic a., hypoglossal a., proatlantal intersegmental a., ** posterior communicating a. (PCA), -- normal anastomosis of carotid to BASILAR artery) (12 Dec 1998) |
| carpal artery | <anatomy, artery> Arteries related to and supplying the wrist joint. See: dorsal carpal branch of radial artery, dorsal carpal branch of ulnar artery, palmar carpal branch of radial artery, palmar carpal branch of ulnar artery. (05 Mar 2000) |
| parietal branch of medial occipital artery | <anatomy, artery> An anterior branch of the medial occipital artery supplying the posterior section of the parietal lobe of the cerebrum. Synonym: ramus parietalis arteriae occipitalis medialis. (05 Mar 2000) |
| parietal branch of middle meningeal artery | <anatomy, artery> Smaller terminal branch (with frontal branch) of middle meningeal artery supplying posterior portion of lateral and superior dura and cranium. Synonym: ramus parietalis arteriae meningeae mediae. (05 Mar 2000) |
| parietal branch of superficial temporal artery | <anatomy, artery> Branches coursing in relationship to and/or supplying the parietal lobe of the brain. Synonym: ramus parietalis arteriae temporalis superficialis. (05 Mar 2000) |
| parieto-occipital artery | <anatomy, artery> The largest cortical branch of the pericallosal artery supplying the medial and superolateral surface of the parietal lobe posterior to the paracentral lobule; rarely does it extend to supply part of the occipital lobe. Synonym: arteria parieto-occipitalis, superior internal parietal artery. (05 Mar 2000) |
