Sacral arteries and their role in the blood supply to the rectum
In modern medical science, there is no consensus on the role of the middle and lateral sacral arteries in the blood supply to the rectum. Some authors believe that these vessels in the body are not sufficiently developed in order to play a significant role in blood supply. But there is also an opposite opinion. Thus, some authors believe that, despite the fact that some parameters of the sacral arteries (we are talking about severity and size) can vary significantly, they are an important, albeit backup, source of intestinal blood supply.
Recall that the sacral arteries are a very fragile bioconstruction (their size can vary from a thin, almost filamentous branch to a sufficiently thick vessel with a cross-section of 1.5 mm). Some authors even describe it as a rudimentary organ. However, to be fair, it should be noted that all such studies, including angiography, were performed on deceased people. They need to be supplemented by modern data obtained by the in vivo method.
Why is it so important to study the features of the sacral arteries and their possible functions in the blood supply to the rectum? Because today, new methods of treating various pathologies (including aneurysms), as well as endovascular treatment of pelvic cancer, will be introduced into medical practice.
To date, there is a study conducted by a team of doctors from VNMA named after N.N. Burdenko (Voronezh), which involved more than 150 patients. All of them were examined for atherosclerotic lesions of the arteries of the lower extremities. As a result, it was found that the sacral arteries can be traced in about 21% of cases, and the diameter of the vessel varies greatly. It would be difficult to assess the degree of involvement of this artery in the intestinal blood supply even with the help of modern equipment. However, the conclusions were drawn based on the assessment of the images.
The conducted studies showed that in a sample of 153 people, in only three cases well-defined sacral arteries supplied blood to the lower and middle ampullary sections of the rectum. Based on the observations, the authors concluded that the artery feeds the intestine intermittently, but theoretically it is possible. And the data revealed must be taken into account in the treatment of diseases of the rectum and pelvic organs. 1xBet No Deposit Free Bet.
