Cerebral vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...
Fig. 1: Dolichoectasia of the suprasellar segment of the left internal carotid artery with compression of the optic chiasm. Most commonly affected are the vertebral and basilar arteries (Vertebral Basilar Dolichoectasia or Vertebrobasillar Dolichoectasia). The internal carotid artery may also be affected.
Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T ...
Arteriosclerosis is any hardening (and loss of elasticity) of medium or large arteries (from the Greek arteria, meaning artery, and sclerosis, meaning hardening) Atherosclerosis is a hardening of an artery specifically due to an atheromatous plaque. The term atherogenic is used for substances or processes that cause atherosclerosis.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
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 ...
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282 . The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9.
The most common cause of arterial stenosis is atherosclerosis, however other pathologies such as fibromuscular dysplasia, dissection, trauma or external compression may occur. [2] Atherosclerotic plaque can rupture, resulting in a source of emboli. These emboli can cause TIAs or strokes in the areas of the brain supplied by the affected artery.
