Aneurysm Dissecting

Aneurysm Dissecting is an aneurysm in which an internal destructive gap occurs, which separates the individual layers of the aneurysm wall into different cavities. Thus, instead of one continuous cavity, several smaller ones appear in the wall of the aneurysm. Aneurysm Dissecting is a special pathological condition that represents pathological changes in blood vessels that cause disruption of vascular function and disruption of blood flow. This vascular disease occurs in people of any age, and it affects both men and women equally often.

This pathology causes a progressive course of the disease: an increase in the size of the aneuryse itself, the development of complications from various body systems. The development of aneurysms in humans can lead to hemorrhages, that is, to serious health consequences. Therefore, when aneurysms are detected, adequate treatment is necessary. Treatment will depend on the type of aneurym and size.

A dissecting aneurysm is a pathological formation on the walls of an artery, which is caused by their division into several membranes. Unlike a diffuse aneurysm, where the membrane remains intact, in the dissecting type there is its division into two or more layers.

The formation is usually characterized by detachment of the inner shell while maintaining the outer shell. In the intima, the inner membrane may remain around the vessel for some time. The size of such a lesion can vary from millimeters to centimeters.

In accordance with the structure of the anomaly, depending on the state of the inner shell, the following forms of pathology are formed:

aneurysms with membranes that are not separated from each other, but are thinned, the walls look like a cone directed inward; external dissecting with thinning and separation of connective tissue into layers; these are the most common pathological changes, when the outer wall cannot be distinguished from the inner one.

Isolated dissecting aneurysm can be either right or left. There may also be unilateral forms of the disease without signs of direction of blood flow in one direction or the other.

An aneurysm is a bulge in the wall of an artery. That is, a pathologically altered section of the artery, which is located above its normal location relative to the lumen and becomes thinner closer to the depletion of the lumen. The diagnosis is considered an idiom, that is, it means absolutely the entire disease or syndrome of a given arterial lesion for all patients.

Aneurysms can be congenital or acquired, carrying the same threat to the patient. Both are not the object of medical competence and definition. Acquired ones have two subgroups: traumatic and therapeutic. Traumatic ones appear as a result of damage to the walls, for example, from a blow or rupture, and therapeutic ones arise as a result of some effect on the vascular system. For example, during pregnancy, the walls of the arteries are stressed. In young women they are a consequence of hormonal changes, in men - age-related changes in the heart. This leads to weakening. The walls become thinner and there are opportunities for the formation of an aneurysm. Traumatic aneurysms occur either soon after the injury or some time after (1.5-2 weeks). The mechanism of their formation involves rupture of the vessel membrane and penetration of the contents into the lumen. During or after an injury, separation of the damaged vessel can occur - arterial bifurcation. In this case, the entire inner lining of the vessel is damaged. Its contents come out, which leads to an increase in its size. Tissues from the outside also act on this fragment of the artery, causing its formation until a certain final diameter is reached. Traumatic aneurysms account for up to 40-48% of cases. But the injury must be quite serious. Often this is an open injury. In people in road accidents. There is about a 20% chance of aneurysms appearing at the site of bruises of the skull and other bones of the vault, but no more than 5% in people without injuries to the bones of the head. It has been noticed that head injuries not only in themselves, but also head concussion always contribute to the development of this disease. The same is true for traumatic brain injuries with all the ensuing consequences.
