Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.
aneurysm of unspecified site (diagnosis)
Constriction, Pathologic [Disease/Finding]
The condition of an anatomical structure's being constricted beyond normal dimensions.
estenosis adquirida (anomalía morfológica)
Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.

Pathologic calcification, calcified structure
Pathologic calcification, calcified structure (morphologic abnormality)
Pathologic deposition of calcium salts in tissues. Deposits of calcium in the tissues. Calcification in the breast can be seen on a mammogram, but cannot be detected by touch. There are two types of breast calcification, macrocalcification and microcalcification. Macrocalcifications are large deposits and are usually not related to cancer. Microcalcifications are specks of calcium that may be found in an area of rapidly dividing cells. Many microcalcifications clustered together may be a sign of cancer. Having calcium deposited on or in an anatomic structure.

Plaque, Atherosclerotic [Disease/Finding]
yellowish plaques containing cholesterol, lipoid material, and lipophages formed within the intima and inner media of large and medium-sized arteries in atherosclerosis.
spasm of the blood vessels resulting in decrease in their caliber.
An idiopathic, segmental, nonatheromatous disease of the musculature of arterial walls, leading to STENOSIS of small and medium-sized arteries. There is true proliferation of SMOOTH MUSCLE CELLS and fibrous tissue. Fibromuscular dysplasia lesions are smooth stenosis and occur most often in the renal and carotid arteries. They may also occur in other peripheral arteries of the extremity.

AV - Congenital arteriovenous malformation
AVM - Congenital arteriovenous malformation
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.

disección de la arteria carótida (trastorno)
dissection of carotid artery (diagnosis)
Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.
Internal carotid artery structure (body structure)
estructura de la arteria carótida interna
estructura de la arteria carótida interna (estructura corporal)
Common carotid artery structure (body structure)
The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.
estructura de la arteria carótida común (estructura corporal)
Structure of carotid sinus (body structure)
estructura de seno carotídeo (estructura corporal)
estructura del seno carotídeo (estructura corporal)
slight dilation in the carotid artery at its bifurcation into the external and internal carotid arteries; it contains baroreceptors (pressure sensors) that when stimulated, will cause a reflex slowing of the heart, vasodilation and a fall in blood pressure.
Structure of vertebral artery (body structure)
The first branch of the SUBCLAVIAN ARTERY with distribution to muscles of the NECK; VERTEBRAE; SPINAL CORD; CEREBELLUM; and interior of the CEREBRUM.
estructura de arteria vertebral (estructura corporal)
estructura de la arteria vertebral (estructura corporal)
Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck.

Structure of brachiocephalic artery (body structure)
The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.
estructura de la arteria braquiocefálica
estructura de la arteria braquiocefálica (estructura corporal)
estructura del tronco braquiocefálico (estructura corporal)
Artery arising from the brachiocephalic trunk on the right side and from the arch of the aorta on the left side. It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.
Structure of subclavian artery (body structure)
estructura de arteria subclavia (estructura corporal)
estructura de la arteria subclavia (estructura corporal)
Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).
