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

A radiograph of blood vessels taken during the (I)angiography(/I) process.

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.

1. Angiography is the termination of the arrangement of blood or lymph vessels without dissection, by capillaroscopy, fluoroscopy, or radiography.
2. Angiography is also 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.

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.

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.

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".

Known as "vasodilatation", it is a dilatation of the blood vessels: especially, the functional increase of the arteriolar lumen.

Like or resembling a blood or lymph vessel.

Tending to invade the walls of blood vessels.

Inflammation of a blood vessels of the ear. From angi- plus otos, "ear", plus -itis, "inflammation".

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.

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.

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.

Relating to, causing, or regulating constriction or dilation of blood vessels.

Inflammation of a lymphatic vessel or vessels.

Acute lymphangitis may result from spread of bacterial infection (most commonly beta-hemolytic streptococci) into the lymphatics, manifested by painful subcutaneous red streaks along the course of the vessels.
