Carotid endarterectomy itself can cause strokes, so to be of benefit in preventing strokes over time, the risks for combined 30-day mortality and stroke risk following surgery should be < 3% for asymptomatic people and ≤ 6% for symptomatic people. [1] The carotid artery is the large vertical artery in red.
Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...
Less common symptoms are artery sounds , or ringing in the ears . [6] In asymptomatic individuals with a carotid stenosis, the risk of developing a stroke is increased above those without a stenosis. The risk of stroke is possibly related to the degree of stenosis on imaging.
Anaplastic thyroid cancer typically manifests as a rapidly enlarging neck mass. [2] Associated redness and swelling of the overlying skin sometimes occur. ATC commonly causes symptoms by compressing local structures, such as the esophagus, carotid arteries, recurrent laryngeal nerve and trachea.
Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...
The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery bypass surgery proves difficult. Livesay [3] in Texas and Nair [4] in Leeds have published the largest series in the world.
Carotid stenosis can have no symptoms, or have symptoms such as transient ischemic attacks (TIAs) or strokes. While historically endarterectomy has been the treatment for carotid stenosis , stenting is an alternative intervention for patients who are not candidates for surgery.
Carotid paraganglioma (carotid body tumor): Is the most common of the head and neck paragangliomas. It usually presents as a painless neck mass, but larger tumors may cause cranial nerve palsies, usually of the vagus nerve and hypoglossal nerve .
