angi-, angio-, angei-, -angium +

(Greek > Latin: [receptacle], vessel, often a blood vessel; "covered by a seed or vessel", a seed vessel; a learned borrowing from Greek meaning "vessel", "container")

angiogram
A radiogram of blood vessels, made after injection of a contrast medium and taken during angiography.
angiograph
A radiograph of blood vessels taken during angiography
angiographic
1. Radiography of vessels after the injection of a radiopaque contrast material; usually requires percutaneous insertion of a radiopaque catheter and positioning under fluoroscopic control.
2. A special kind of sphygmograph or instrument for recording on paper the movements of the pulse.
angiography
1. Determination of the arrangement of blood or lymph vessels without dissection, by capillaroscopy, fluoroscopy, or radiography.
2. The radiographic visualization of blood vessels following introduction of contrast material; used as a diagnostic aid in such conditions as stroke syndrome and myocardial infarction.
angiohemophilia
A form of hemophilia discovered by Erik von Willebrand; a genetic disorder that is inherited as an autosomal recessive trait; characterized by a deficiency of the coagulation factor and by mucosal bleeding.

An inherited bleeding disorder in which a clotting protein called von Willebrand factor is deficient or defective. Von Willebrand factor is made by cells lining the wall of blood vessels.

When vessels are damaged, platelets normally clump at the site of the injury. Von Willebrand factor acts as glue to help the platelets clump.

The Von Willebrand factor is also a carrier of clotting factor VIII, another protein that helps the blood to clot.

angiohyalinosis
Hyaline degeneration of the walls of the blood vessels.

Hyaline degenerationz, refers to a group of several degenerative processes that affect various cells and tissues, resulting in the formation of rounded masses ("droplets") or relatively broad bands of substances that are homogeneous, translucent, refractile, and moderately to deeply acidophilic; may occur in the collagen of old fibrous tissue, smooth muscle of arterioles or the uterus, and as droplets in parenchymal cells.

angiohypertonia (s) (noun), angiohypertonias (pl)
Also known as "vasospasm", the sudden decrease in the internal diameter of a blood vessel that results from contraction of smooth muscles within the wall of the vessel. An angiohypertonia causes a decrease in blood flow, but an increase in systemic vascular resistance or "vasoconstriction".
angiohypotonia (s) (noun), angiohypotonias (pl)
Known as "vasodilatation", it is a dilatation of the blood vessels: especially, the functional increase of the arteriolar lumen.
angioid
Like or resembling a blood or lymph vessel.
angioinvasive
Tending to invade the walls of blood vessels.
angioitis
Inflammation of a blood vessels of the ear. From angi- plus otos, "ear", plus -itis, "inflammation".
angiokeratoma, angioceratoma
1. A skin disease characterized by clusters of dilated blood vessels and by thickened skin, forming warty growths; especially, on the scrotum, fingers, and toes.
2. An intradermal cavernous hemangioma covered by a wartlike thickening of the horny layer of the epidermis. Also called telangiectatic wart.
angiokeratosis
1. A condition characterized by multiple angiokeratomas.
2. A discrete, pink to red telangiectasia having a tendency to undergo secondary epithelial changes, including acanthosis and hyperkeratosis. An underlying vascular abnormality is present in many cases.
angiokinesis
1. Relating to, causing, or regulating constriction or dilation of blood vessels.
2. Change in the caliber of a blood vessel; also, vasomotion or vasomotor.
angiokinetic
Relating to, causing, or regulating constriction or dilation of blood vessels.
