Anastomosis

Anastomosis is a surgical connection between two structures. It generally means a connection created between tubular structures, such as blood vessels or the loops of the intestine . In the human body there is a large amount of anastomosis, both between arteries and between veins , usually of a small caliber.

These anastomoses allow that, when one of the vessels is disabled , the unscathed vessel can supply the occluded or ligated one and that no necrosis occurs due to lack of circulation . There are some organs where these anastomoses are rare, such as in the heart and brain , so the occlusion of one of the arteries leads to a heart attack .

When part of an intestine is surgically removed , the remaining two ends are sewn or stapled together (anastomosed). The procedure is known as an intestinal anastomosis .

Etymology

The word anastomosis is used in biology , geology, and medicine . The word is very old and comes from the Renaissance Latin anastomosis, in which it was mainly applied to the making of a hole by surgical techniques, a voice that has been taken from the Greek ἀναστόμωσις (“anastómosis”).

Examples of surgical anastomoses

Surgically, anastomoses are performed to promote the circulation of an organ , as is the case with coronary weights .

  • Arteriovenous fistula(an opening created between an artery and a vein ) for dialysis .
  • Colostomy(an opening created between the intestine and the abdomen )
  • Intestinal, in which two ends of the intestine are sutured
  • A connection between a graftand a blood vessel to create a bypass
