		It is in relation, behind, with the Longus capitis, the superior cervical ganglion of the sympathetic trunk, and the superior laryngeal nerve; laterally, with the internal jugular vein and vagus nerve, the nerve lying on a plane posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
		The artery is separated from the bony wall of the carotid canal by a prolongation of dura mater, and is surrounded by a number of small veins and by filaments of the carotid plexus, derived from the ascending branch of the superior cervical ganglion of the sympathetic trunk.
		As the artery crosses the optic nerve it is accompanied by the nasociliary nerve, and is separated from the frontal nerve by the Rectus superior and Levator palpebræ superioris.

		The two largest are the two internal carotid arteries, the left and right branches of the common carotid arteries in the neck which enter the skull, as opposed to the external carotid branches which supply the facial tissues.
		Both internal carotid arteries, within and along the floor of the cerebral vault, are interconnected via the anterior communicating artery.
		In case one of the supply arteries is occluded, the Circle of Willis provides interconnections between the internal carotid arteries and basilar artery along the floor of the cerebral vault, providing blood to tissues that would otherwise become ischemic.

		Carotid duplex is an ultrasound procedure performed to assess blood flow through the carotid artery to the brain.
		Carotid ultrasound (also called Doppler or duplex sonography) is used to determine blockage in the carotid arteries that could lead to or be causing a stroke.
		With this procedure a healthy artery in the scalp is rerouted to an area of the brain that was deprived of blood because of a blocked artery.

		The internal carotid arteries supply the majority of both cerebral hemispheres, except the occipital and medial temporal lobes, which are supplied from the posterior circulation (see Image 1).
		The internal carotid artery originates at the bifurcation of the common carotid artery at the level of the thyroid cartilage in the neck.
		The most common causes of arterial occlusion involving the major cerebral arteries are (1) emboli, most commonly arising from atherosclerotic arterial narrowing at the bifurcation of the common carotid artery, from cardiac sources, or from atheroma in the aortic arch and (2) a combination of atherosclerotic stenosis and superimposed thrombosis.

	Thoracic Cardiovascular Institute - Carotid Endarterectomy
		As the plaques enlarge, the arteries become narrow and stiff, a process called atherosclerosis or 'hardening of the arteries.' Plaque buildup is typically seen in the carotid artery at the point where it branches into the internal and external carotid arteries and in the origin, or lower part, of the internal carotid artery.
		Endarterectomy is a treatment for carotid arteries that are partially blocked by atherosclerotic plaque, and is usually only done when the amount of partial blockage is severe enough to threaten a stroke.
		The sections of the common, external, and internal carotid arteries affected by plaque buildup are separated from surrounding tissue and are clamped to temporarily stop blood from flowing through them.

	Carotid Artery (Site not responding. Last check: 2007-10-08)
		Carotid endarterectomy is an operation in which a seriously narrowed carotid artery is opened up to allow better flow of blood to the brain.
		The usual cause of this narrowing is a cholesterol deposit (atheroma) at the beginning of the internal carotid artery (white arrow).
		A detour will be put in the carotid artery in the area of blockage so that blood flows to the brain without significant interruption while the narrowed artery is being cleared out.

		The carotid arteries are the four principal arteries of the neck and head.
		They have two specialized regions: the carotid sinus, which monitors the blood pressure, and the carotid body, which monitors the oxygen content in the blood and helps regulate breathing.
		At the base of the brain, the two internal carotids and the basilar artery join to form a ring of blood vessels called the "circle of Willis." The external carotid arteries have several branches which supply the tissues of the face, scalp, mouth and jaws.

	AllRefer Health - Carotid Artery Surgery (Carotid Endarterectomy) - Surgery & Procedures
		Carotid artery surgery is a surgical procedure to remove fat and cholesterol build-up (plaque) from inside the carotid artery in the neck and restore adequate blood flow to the brain.
		Each common carotid splits into two branches, the internal branch which brings oxygen-rich blood to the brain, and the external branch, which brings blood to the face.
		When the internal carotid arteries become blocked by fat and cholesterol build-up as a result of atherosclerosis, the patient may experience symptoms, such as blurred vision, slurred speech, or weakness (all signs of stroke).

		A solid 0.47 mm diameter nylon thread was inserted into the right common carotid artery toward the ascending aorta up to 10−12 mm from the upper edge of the right sternomastoid muscle, followed by ligation with a 0.09 mm diameter nylon thread (preischemic rats) (Fig.

	Medical Aspects: Blood Supply
		The vertebral arteries and the basilar are straight arteries and therefore not as subject to blockages due to the build up of cholesterol as are the internal carotids.
		As the vertebral and basilar are somewhat wide arteries and their course is relatively straight, they are not as subject to blockages caused by the build-up of cholesterol as the internal carotids.
		Thus, the ends of the internal carotids and the basilar artery enter the Circle while the three cerebral arteries arise and exit from it.

		Blood is supplied to the brain through two pairs of large arteries: the internal carotid arteries and the vertebral arteries.
		The internal carotid arteries carry blood from the heart along the front of the neck, and the vertebral arteries carry blood from the heart along the back of the neck.
		The major risk factors for both types of stroke are atherosclerosis (the narrowing or blockage of arteries by patchy deposits of fatty material in the walls of arteries), high blood pressure, diabetes, and smoking.

		Stenting is a procedure in which a balloon-tipped catheter is inserted into an artery and advanced to the point of blockage. The balloon is inflated to open the artery. A stent is a wire mesh tube used to prop open a blocked artery.
		Historically, about 40 percent of patients with strokes caused by total blockage of the internal carotid artery suffer severe disability and 20 percent of patients die within three months of stroke, he said.
		blockages were thought to be too big to be handled surgically by carotid endarterectomy or by stenting. Carotid endarterectomy is a procedure to surgically remove plaque from the carotid artery.

		Often, ischemia in the distribution of the ophthalmic artery is transient in the setting of symptomatic internal carotid artery occlusion (ie, transient monocular blindness, occurring in approximately 25% of patients), but central retinal artery ischemia is relatively uncommon, presumably because of the efficient collateral supply.
		The intracranial arterial occlusive disease in these populations typically involves the main stem of the MCA or the ACA.
		In Caucasians, the arterial occlusive disease typically involves the extracranial carotid arteries, and lesions in the middle and anterior cerebral arteries are usually of embolic origin.
