In anatomy, the left and right common carotid arteries (carotids) (English: /kəˈrɒtɪd/ ) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries. It begins at the bifurcation of the common carotid, in the thyroid cartilage, and then enters through the carotid duct and ends up dividing into the anterior cerebral artery and the middle cerebral artery. When this obstruction is constant and untreated, strokes can occur, either from a blood clot or from the detachment of pieces of plaque. The right and left common carotid arteries run up the neck on the respective side in the carotid sheath along with the internal jugular vein and vagus nerve. The locations of the paraclinoid aneurysms were categorized into intradural (aneurysm neck and sac located above the DDR), transdural (aneurysm neck or sac were straddling the DDR), and extradural (aneurysm neck and sac located below the DDR). Within minutes, brain cells begin to die. A severe blockage could cause a stroke because it would reduce blood flow to the brain. During the procedure, surgical occlusion of the common carotid artery proximal to the arterial sheath location creates a "reversal of flow," with blood flowing away from the brain through the neuroprotection system, returning the blood via the venous system. A carotid bruit is a vascular murmur sound heard over the carotid artery area on auscultation during systole. The carotid sinus, or carotid bulb, is a widening of a carotid artery at its main branch point. Carotid arteries are located on each side of the neck and are the blood vessels that supply oxygenated blood to the head, neck and brain.

The proximal internal carotid artery and the carotid bifurcation are the locations most frequently affected by carotid atherosclerosis. The carotid artery is the large artery that delivers newly oxygenated blood from the heart to the head and neck. As it does so, it forms the internal and external carotid arteries which go on to supply the head and neck. Most often, strokes occur when a blood clot blocks a blood vessel to the brain. The internal carotid artery is born at the angle of the mandible, from the right and left common carotid arteries, which bifurcate to shape these arteries.

Carotid artery disease can be dangerous, as it impacts the blood supply to the brain and significantly increases your risk of having a stroke or a transient ischemic attack (TIA). Cervicocerebral arterial dissections (CAD) are an important cause of strokes in younger patients accounting for nearly 20% of strokes in patients under the age of 45 years. Its path places it right alongside brain regions associated with visual and sensory processing and, at its end, it splits into the two cerebral arteries. Search terms included: natural history, carotid artery disease, and stenosis, lesion size, location, prevalence, and natural history, risk factors, survival rates, medical therapy, surgical intervention, and mortality. The vertebra-basilar system supplies blood when the carotid artery cannot do so (due to a blockage, for example). Most patients who have a stroke from CAD do not have warning symptoms before the stroke occurs. Unfortunately, this surgery is not without risk. It arises from the bifurcation of the common carotid, just at the top edge of the thyroid cartilage, at the level of the fourth cervical vertebra. Spontaneous extracranial internal carotid artery dissection may originate near the level of the skull base and involves the distal portion of the cervical segment 14.
