Arterial intersystemic anastomosis

Arterial intersystem anastomosis (a. intersystemica arterialis) is an anatomical formation that connects arteries of different circulatory systems. This type of anastomosis plays an important role in regulating blood flow and maintaining metabolism in the body.

An intersystem arterial anastomosis can connect arteries of different systems, such as the arterial system and the venous system, as well as systems of different organs. For example, an anastomosis between the arteries of the heart and the arteries of the brain ensures the exchange of oxygen and nutrients between these organs.

In addition, intersystem arterial anastomosis plays an important role in maintaining pressure in the arteries of different systems. When one artery increases in diameter, the pressure in it can decrease, which can lead to decreased blood flow in another artery that is connected to the first.

To ensure normal functioning of the body, it is necessary that the intersystem arterial anastomosis function correctly. However, if this anastomosis is damaged or missing, it can lead to disruption of the blood supply to organs and tissues, as well as various diseases.

Thus, the intersystem arterial anastomosis is an important anatomical formation that ensures normal functioning of the body and maintains blood pressure.

Arterial intersystem anastomosis (AIA) is the formation of a new connection between two or more branches of the same vascular system. It represents a certain response to the development of a particular organ, which changed during the evolution of the organism for various reasons. Usually in this case, several possible options for the development of relations between the internal systems of the body are identified, and the manifestation of one or more of them led to the creation of a new connection. The organ that formed the connection began to act to improve metabolism in this area, its degree of pressure, elasticity, influx of oxygen and nutrients, etc. increased. All of these factors will ultimately lead to the successful occurrence of natural processes, improvement of functions and wider development. As for the importance of aortic anastomoses, in addition to improving blood flow, they also help reduce the load on the cardiovascular system and, if detected early, will save the patient’s life during a heart attack. AMAs are most often found in the heart and may involve anastomoses between branches of the right or left aortic arch. These artery connections can be small or large, complex or simple. They can be congenital or acquired. They are more common in men due to the anatomical features of the cardiovascular system. At the moment, there is no clear indication of the frequency of detection of a particular type of anastomosis. This can vary from 6 to 25%. The nature of the flow can be sudden - critical and latent. The formation of a critical type is characterized by a sharp deterioration in health, the course of which is aggravated if surgical measures are not taken in a timely manner. In addition, in this case the risk of death is high. The latent type is discovered by chance or during X-ray examination
