2. The connection or communication between two tubular organs of normally separate parts or spaces so they intercommunicate.
3. The connection or place of connection of two or more parts of a natural branching system; for example, of blood vessels, leaf veins, stems of woody plants, or rivers.
4. The surgical union of two hollow organs: such as, blood vessels or parts of the intestine, to ensure continuity of the passageways.

An anastomosis may be naturally occurring or artificially constructed and be created during the process of embryonic development or by surgery, trauma, or pathological means.

For example, an anastomosis may connect two blood vessels (as in a naturally occurring arteriovenous anastomosis, a connection between an artery and a vein) or it may connect the healthy sections of the colon or rectum after a cancerous or otherwise diseased portion has been surgically removed.

A gastrojejunal anastomosis connects the stomach directly with the jejunum or part of the small intestine.

The term anastomosis comes from Greek. It originally referred to an opening or junction through a mouth as of one body of water with another.

Anastomosis has been in medical usage since the Greek physician Galen (129-200 A.D.) used it to describe the interconnections between blood vessels.

A separation in the rings in tree trunks; wind shake: Anemones is a condition in which the annual layers of certain trees are separated from one another, frequently attributed to the effects of strong winds bending the tree trunks, although some believe the conditions result from exposure to frost or lightning.

Fibrosis (tissue or fibers laid down at a wound site) of the walls of blood vessels.

Glial scarring about a blood vessel or a condition of multiple angiogliomas.

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.

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.

A diseased state of the vessels with the formation of multiple angiomas.

Death of blood vessels or necrosis of the walls of blood vessels.

Any disorder of the vasomotor nerves; neurosis of a blood vessel.
