[ə‚nas·tə′mō·səs]
(medicine)
A surgical communication made between blood vessels, for example, between the portal vein and the inferior vena cava.
An opening created by surgery, trauma, or disease between two or more normally separate spaces or organs.
(science and technology)

A network of parts or branches created by the process of anastomosis.

Anastomosis

 

in animals, connections between nerves, muscles, and blood or lymphatic vessels. Anastomoses between arteries and veins, without the formation of capillary networks—that is, arteriovenous anastomoses—are of importance in regulating the blood supply of organs. In clinical practice, anastomosis is the name given to a connection between tubular organs which is artificial or has arisen as a consequence of disease. In higher plants, anastomosis is the connecting of tubular structures—for example, veins in leaves and branchings of latex vessels. In fungi, anastomosis is the connecting or concresence of two mycelium hyphae with the establishing of intercommunication between them. This occurs with an insufficiency of food and plays a role in the formation of diploid mycelium and the heterokaryon of haploid mycelium, since the cell nuclei move from one cell into another through the anastomoses.

The patients were monitored post-operatively for pulmonary (respiratory failure needing ventilatory support, atelectasis, pneumonia, pulmonary embolism, pleural effusion/hemothorax, etc.), cardiac (arrhythmias, myocardial infarction, and congestive cardiac failure), and surgical complications (wound infections, anastomotic leak, and fistula formation).

Although wound dehiscence was observed in both groups with insignificant statistics yet anastomotic leak was found to have significant correlation ruling out the jejunostomy as a cause of the dehiscence.
In event of AUR or anastomotic leakage, a14Fr or 16Fr Foley catheter was reinserted by a heath care provider or a medical nurse without cystoscopic guidance, and the patient was instructed to keep the catheter for 3-7 days to allow the VUA edema to resolve.
