The carotid artery is the large vertical artery in red. The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy ...
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 ...
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 ...
Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. 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 ...
The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch. At the throat it forks into the internal carotid artery and the external carotid ...
Zamboni and colleagues claimed that in MS patients diagnosed with CCSVI, the azygos and IJV veins are stenotic (abnormally narrowed) in around 90% of cases. Zamboni theorized that malformed blood vessels cause increased deposition of iron in the brain, which in turn triggers autoimmunity and degeneration of the nerve's myelin sheath.
Immediately following coronary artery or neurosurgical vascular bypass surgery, patients recover in an intensive care unit or coronary care unit for one to two days. Provided that recovery is normal and without complications, they can move to a less intensively monitored unit such as a step-down unit or a ward bed. Depending on the extent of ...
Blood flow through an artery is partially occluded by the deposition of an atherosclerotic plaque. Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues.
