An anastomosis (plural anastomoses, from gr. ἀναστόμωσις, communicating opening) is a network of streams that both branch out and reconnect, such as blood vessels or leaf veins. The term is used in medicine, biology, and geology.
Pathological anastomosis results from trauma or disease and may involve veins, arteries, or intestines. These are usually referred to as fistulas. In the cases of veins or arteries, traumatic fistulas usually occur between artery and vein. Traumatic intestinal fistulas usually occur between two loops of intestine (enetero-enteric fistula) or intestine and skin (enterocutaneous fistula). Portacaval anastomosis, by contrast, is an anastomosis between a vein of the portal circulation and a vein of the systemic circulation, which allows blood to bypass the liver in patients with portal hypertension, often resulting in hemorrhoids, esophageal varices, or caput medusae.
There is also a type of stream or river called anastomosing, which consists of a wide strath and multiple thalwegs divided by vegetated stabilized islands within subparallel banks.
