Anastomosis

Anastomosis

(from the Greek anástomos - “restore” + – itis “recession”) - inflammatory or cicatricial narrowing of the diameter or deformation of the anastomosis due to a pathological process in the tissues or organs that form it: * thrombosis of the anastomosis * obliterating endarteritis or atherosclerosis * extensor (induction) ) trauma with vascular injury * degenerative changes in blood vessels after infection * anastomosis aneurysm (small arterioscoliosis gyrus) _Can be isolated and accompany other diseases, such as cardiovascular diseases. The narrowing of the lumen may have a slight effect on the blood supply to an organ (for example, the hand), may completely lead to its exclusion from the blood circulation, and may be complicated by the development of ischemia and gangrene [1].

In case of complete blockage of blood flow, the tissues that were supplied with blood through this anastomosis atrophy. Typically, blood circulation in these tissues continues along pre-existing collaterals (through other vessels). Due to their larger diameter, collateral vessels cannot always perform the function of a lost anastomosis (that is, dried/venous blood in the collateral branch of the artery/arterioles is formed with a large pressure gradient). This will lead to malnutrition and atrophy of the downstream distal sections, so more often than not, circulation is restored over time. Although there is a defect with maximum circulatory impairment and atrophy of life-supporting organs.
