Anastomosis (plural anastomoses) describes a form of network in i beg your pardon streams both branch out and also reconnect. The ax is offered in medicine, biology, and geology.

Anastomosis is the surgical link of two structures.<1> It frequently refers to connections in between blood vessels or connections between other tubular frameworks such as loops that intestine. In circulatory anastomosis, plenty of arteries normally anastomose with each other. For example: the inferior epigastric artery and also superior epigastric artery. In surgery, operation anastomosis occurs when a segment the intestine is resected and also the two continuing to be ends room sewn or stapled together (anastomosed). The procedure is described as minister anastomosis.

Pathological anastomosis outcomes from trauma or an illness and might involve veins, arteries, or intestines. These room usually described as fistulas. In the cases of veins or arteries, traumatic fistulas generally occur in between artery and vein. Traumatic minister fistulas generally occur in between two loops the intestine (enetero-enteric fistula) or intestine and also skin (enterocutaneous fistula). Portacaval anastomosis, through contrast, is one anastomosis in between a vein the the portal circulation and also a vein the the systemic circulation, which permits blood come bypass the liver in patients with portal hypertension, regularly resulting in hemorrhoids, esophageal varices, or caput medusae.


In evolution, anastomosis is a recombination of evolutionary lineage. Standard accounts of evolution lineage current themselves as the simple branching the end of types into novel forms. Under anastomosis, varieties might recombine ~ initial branching out, such together in the situation of current research which mirrors that humans and chimpanzees may have actually interbred after an early branching out.<2> A second case in i beg your pardon the idea the anastomosis finds applications is in the concept of Symbiogenesis, in which brand-new forms the life (species) room seen to arise from the formation of novel symbiotic relationships.


In geology, anastomosis is provided to describe quartz (or other) veins displaying this property, i m sorry is often related come shearing in metamorphic regions. Over there is additionally a form of stream referred to as anastomosing, which consists of a vast strath and also multiple thalwegs split by vegetated stabilized islands in ~ subparallel banks.
