1. communication between two tubular organs.
2. surgical, traumatic, or pathologic formation of a connection between two normally distinct structures. adj., adj anastomot´ic.
arteriovenous anastomosis
anastomosis between an artery and a vein.
Simple arteriovenous anastomosis. From Dorland's, 2000.
crucial anastomosis an arterial anastomosis in the upper part of the thigh, formed by the anastomotic branch of the sciatic artery, the internal circumflex artery, and the first perforating and transverse portions of the external circumflex artery.
end-to-end anastomosis
1. an anastomosis connecting the end of an artery and that of some other vessel, either directly or with a synthetic graft.
2. anastomosis of two sections of colon, such as with partial colectomy or when an ileostomy is closed.
end-to-side anastomosis an anastomosis connecting the end of one vessel with the side of a larger one.

2. surgical, traumatic or pathological formation of a connection between two normally distinct structures.
arteriovenous anastomosis
anastomosis between an artery and a vein.
cobra-head anastomosis
a technique used in joining grafts to blood vessels. Ends of grafts are trimmed to form an enlarged lumen.
esophageal anastomosis
uniting the free ends after complete resection of a part of the esophagus.
heterocladic anastomosis
one between branches of different arteries.
intercarotid anastomosis
a naturally occurring communication between the internal and external carotid arteries in birds. It provides a collateral pathway for blood to the brain, the counterpart of the cerebral arterial circle of Willis in mammals.
intestinal anastomosis
establishment of a communication between two formerly distinct portions of the intestine.
skin arteriovenous anastomosis
frequent natural occurrence; capable of diverting large volumes of blood to splanchnic circulation during cardiovascular stress.
tracheal anastomosis
end-to-end anastomosis of the trachea after resection of a part.
